Cooling Method Of The Transformer Engineering Essay

Cooling Method Of The Transformer Engineering Essay One of the most important and ubiquitous electrical machines is the transformer. It receives power at one voltage and delivers it at another. This conversion aids the efficient long-distance transmission of electrical power form generating stations. Since power lines incur significant power losses, it is important to minimize these losses by the use of high voltages. The same power can be delivered by high-voltage circuits at a fraction of the current required for low-voltage circuits. The design of the magnetic circuit, the core of the transformer, will first be considered. The significance of the no-load behavior of the transformer is explained and of the magnetizing current which exists under all operating condition. The common form of transformer involves a ferromagnetic core in order to ensure high value of magnetic flux linkage. This is also true of the rotating machine. Although transformers are generally associated with power system applications, they also occur in many low power application including electronic circuits. Transformers effect changes of voltage with virtually no loss of power. BASIC PRINCIPLES The transformer is based on two principles: firstly, that an electric current can produce a magnetic field (electromagnetism) and secondly that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil (electromagnetic induction). Changing the current in the primary coil changes the magnetic flux that is developed. The changing magnetic flux induces a voltage in the secondary coil. An ideal transformer is shown in the adjacent figure. Current passing through the primary coil creates a magnetic field. The primary and secondary coils are wrapped around a core of very high magnetic permeability, such as iron, so that most of the magnetic flux passes through both primary and secondary coils. INDUCTION LAW The voltage induced across the secondary coil may be calculated from Faradays law of induction, which states that: Where VS is the instantaneous voltage, NS is the number of turns in the secondary coil and ÃŽÂ ¦ equals the magnetic flux through one turn of the coil. If the turns of the coil are oriented perpendicular to the magnetic field lines, the flux is the product of the magnetic field strength B and the area A through which it cuts. The area is constant, being equal to the cross-sectional area of the transformer core, whereas the magnetic field varies with time according to the excitation of the primary. Since the same magnetic flux passes through both the primary and secondary coils in an ideal transformer, the instantaneous voltage across the primary winding equals Taking the ratio of the two equations for VS and VP gives the basic equation for stepping up or stepping down the voltage ENERGY LOSSES An ideal transformer would have no energy losses, and would be 100% efficient. In practical transformers energy is dissipated in the windings, core, and surrounding structures. Larger transformers are generally more efficient, and those rated for electricity distribution usually perform better than 98%. Experimental transformers using superconducting windings achieve efficiencies of 99.85%,While the increase in efficiency is small, when applied to large heavily-loaded transformers the annual savings in energy losses are significant. A small transformer, such as a plug-in wall-wart or power adapter type used for low-power consumer electronics, may be no more than 85% efficient, with considerable loss even when not supplying any load. Though individual power loss is small, the aggregate losses from the very large number of such devices is coming under increased scrutiny. The losses vary with load current, and may be expressed as no-load or full-load loss. Winding resistance dominates load losses, whereas hysteresis and eddy currents losses contribute to over 99% of the no-load loss. The no-load loss can be significant, meaning that even an idle transformer constitutes a drain on an electrical supply, which encourages development of low-loss transformers (also see energy efficient transformer). Transformer losses are divided into losses in the windings, termed copper loss, and those in the magnetic circuit, termed iron loss. Losses in the transformer arise from: WINDING RESISTANCE Current flowing through the windings causes resistive heating of the conductors. At higher frequencies, skin effect and proximity effect create additional winding resistance and losses. HYSTERESIS LOSSES Each time the magnetic field is reversed, a small amount of energy is lost due to hysteresis within the core. For a given core material, the loss is proportional to the frequency, and is a function of the peak flux density to which it is subjected. EDDY CURRENTS Ferromagnetic materials are also good conductors, and a solid core made from such a material also constitutes a single short-circuited turn throughout its entire length. Eddy currents therefore circulate within the core in a plane normal to the flux, and are responsible for resistive heating of the core material. The eddy current loss is a complex function of the square of supply frequency and Inverse Square of the material thickness. MAGNETOSTRICTION Magnetic flux in a ferromagnetic material, such as the core, causes it to physically expand and contract slightly with each cycle of the magnetic field, an effect known as magnetostriction. This produces the buzzing sound commonly associated with transformers, and in turn causes losses due to frictional heating in susceptible cores. MECHANICAL LOSSES In addition to magnetostriction, the alternating magnetic field causes fluctuating electromagnetic forces between the primary and secondary windings. These incite vibrations within nearby metalwork, adding to the buzzing noise, and consuming a small amount of power. STRAY LOSSES Leakage inductance is by itself largely lossless, since energy supplied to its magnetic fields is returned to the supply with the next half-cycle. However, any leakage flux that intercepts nearby conductive materials such as the transformers support structure will give rise to eddy currents and be converted to heat. There are also radiative losses due to the oscillating magnetic field, but these are usually small. DOT CONVENTION It is common in transformer schematic symbols for there to be a dot at the end of each coil within a transformer, particularly for transformers with multiple windings on either or both of the primary and secondary sides. The purpose of the dots is to indicate the direction of each winding relative to the other windings in the transformer. Voltages at the dot end of each winding are in phase, while current flowing into the dot end of a primary coil will result in current flowing out of the dot end of a secondary coil. TYPE OF TRANSFORMER There are many types of transformer is there one of them is Air-cored transformer. The air-cored transformer may literally consist of two concentric coils which have nothing but air within the coils. This immediately has the advantage that the magnetizing current has exactly the same waveform as the voltage to which it is related. It has the very significant disadvantage that it is difficult to produce the necessary magnetic flux to generate the appropriate e.m.f. LEAKAGE FLUX The ideal transformer model assumes that all flux generated by the primary winding links all the turns of every winding, including itself. In practice, some flux traverses paths that take it outside the windings. Such flux is termed leakage flux, and results in leakage inductance in series with the mutually coupled transformer windings. Leakage results in energy being alternately stored in and discharged from the magnetic fields with each cycle of the power supply. It is not directly a power loss (see Stray losses below), but results in inferior voltage regulation, causing the secondary voltage to fail to be directly proportional to the primary, particularly under heavy load. Transformers are therefore normally designed to have very low leakage inductance. However, in some applications, leakage can be a desirable property, and long magnetic paths, air gaps, or magnetic bypass shunts may be deliberately introduced to a transformers design to limit the short-circuit current it will supply. Leaky transformers may be used to supply loads that exhibit negative resistance, such as electric arcs, mercury vapor lamps, and neon signs; or for safely handling loads that become periodically short-circuited such as electric arc welders. Air gaps are also used to keep a transformer from saturating, especially audio-frequency transformers in circuits that have a direct current flowing through the windings. COOLING METHOD OF TRANSFORMER Oil is used to cool the transformer. It also provide part of the electrical insulation between internal line parts, transformer oil must remain stable at high temperature for an extended period. Very large or high-power transformer may also have cooling fans, oil pumps, and even oil-to-water heat exchangers. Cooling fan is used in transformer. High temperatures will damage the winding insulation. Small transformers do not generate significant heat and are cooled by air circulation and radiation of heat. Power transformers rated up to several hundred kVA can be adequately cooled by natural convective air-cooling, sometimes assisted by fans. Power transformer rated up to a few KVA can be adequately cooled by natural convective air-cooling, sometimes assisted by fans. Some power transformers are immersed in specialized transformer oil that acts both as a cooling medium, thereby extending the lifetime of the insulation transformer. The transformer gets heated due the iron and copper losses occurring in them. It is necessary to dissipate this heat so that the temperature of the winding is kept below the value at which the insulation begins to deteriorate. The cooling of transformer is more difficult than the rotating machines because these machines create a turbulent air flow, which assists in removing the heat generated due losses. Luckily the losses in transformers are comparatively small. According to cooling system there are two types of transformer 1-> ONAN oil natural air natural 2-> ONAF oil natural air forced Oil natural by means a number of radiators with air natural flow. The radiator is fixed to the tank through individual cut-off valves, provided with a handle operate closing device in line with the radiator connector pipe position, indicate open position of the valve. LOSSES IN TRANSFORMER An ideal transformer would have no energy losses, and would therefore be 100% efficient. In practical transformers energy is dissipated in the windings, core , and surrounding structure. TRANSFORMER OIL TEST Transformer oil can give better insulation level to operate the transformer. It also is a coolant to carry the heat away from the electrical transformer windings and iron core to the cooling radiators on the side of the oil filled transformer. If there is no better insulation level, it produced short circuit in the transformer. There for transformer oil should be checked. Normally moisture and other liquids are mixed with oil, the insulation level is reduced. Normally we can see the silica gel for absorb the moisture of transformer. Also there is an equipment to check the insulation level of transformer. TRANSFORMER OIL Transformer oil, or insulating oil, is usually a highly- refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformer, some types of high voltage capacitors, fluorescent lamp ballasts, and some types of high voltage switches and circuit breakers. Its functions are to insulate, suppress corona and arcing, and to serve as a coolant. EXPLANATION The oils help cool the transformer. Because it also provides part of the electrical insulation between internal live parts, transformer oil must remain stable at high temperatures for an extended period. To improve cooling of large power transformers, the oil-filled tank may have external radiators through which the oil circulates by natural convection. Very large or high-power transformer may also have cooling fans, oil pumps, and even oil-to-water heat exchangers. Large, high voltage transformers undergo prolonged drying processes, using electrical self-heating, the application of a vacuum, or both to ensure that the transformer is completely free of water of water vapor before the cooling oil is introduced. This helps prevent corona formation and subsequent electrical breakdown under load. Oil filled transformer with a conservator tend to be equipped with Buchholz relays. These are safety devices that detect the build of gases inside the transformer and switch off the transformer. Transformer without conservators is usually equipped with sudden pressure relays, which perform a similar function as the Buchholz relay. The flash point and pour point are 140 degree c and -6 degree c respectively. The dielectric strength of new untreated oil is 12MV/m and after treatment it should be > 24MV/M. Large transformer for indoor use must either be of the dry type, that is, containing no liquid, or use a less-flammable liquid. Well into the 1970, polychlorinated biphenyls were often used as a dielectric fluid since they are not flammable. They are toxic, and under incomplete combustion, can form highly toxic products such as furan. Starting in early 1970, concern about the toxicity of PCBs have led to their banning in many countries. Today, non-toxic, stable silicone-based or fluorinated hydrocarbons are used, where the added expense of a fire-resistant liquid offsets additional building cost for a transformer vault. Combustion- resistant vegetable oil-based dielectric coolants and synthetic pentaerythritol tetra fatty acid, ester is also becoming increasingly common as alternatives to naphthenic mineral oil. Esters are non-toxic to aquatic life, readily biodegradable, and have a lower volatility and higher flash points than minerals oil. COOLING PRODUCTS Transformer oil acts as an insulating and cooling medium in transformers. The insulating oil fills up pores in fibrous insulation and also the gaps between the coil conductors and the spacing between the siding and the tank, and thus increases the dielectric strength of the insulation. A transformer in operation generates heat in the winding, and that heat is transferred to the oil. Heated oil then flows to the radiators by convection. Oil supplied from the radiators, being cooler, cools the winding. There are several important properties such as dielectric strength, flash point, viscosity, specific gravity and pour point and all of them have to be considered when qualifying oil for use in transformers. Normally mineral oil is used, but coconut oil has been shown to possess all the properties needed to function as an environmentally friendly and economic replacement to the mineral oil for this purpose. DIFFERENCE BETWEEN AIR COOLED TRANSFORMER AND OIL IMMERSED TRANSFORMER The basic difference between the air cooled transformer and oil immersed transformer is: If the heat generated in the transformer winding is capable of being swapped by the surrounding ambient air without causing any problem to the performance of the transformer then its normally reffered as Naturally Air Cooled transformer or simply air cooled transformer. However when the capacity of the transformer increases, the heat generated in the winding of the transformer is more and the ambient air normally is inadequate to cool the windings and maintain the performance of the transformer. Its because of this reason the transformer windings are submerged in an oil tank. It has been observed that the hydrogen ions present in oil help to maintain the temperature of the winding of the transformer and thus overall performance of transformer. EFFECT OF FREQUENCY The time-derivative term in Faradays Law shows that the flux in the core is the integral with respect to time of the applied voltage. Hypothetically an ideal transformer would work with direct-current excitation, with the core flux increasing linearly with time. In practice, the flux would rise to the point where magnetic saturation of the core occurs, causing a huge increase in the magnetizing current and overheating the transformer. All practical transformers must therefore operate with alternating (or pulsed) current.

Succubus Dreams CHAPTER 10

When I came home from Seth's the next day, there was another note stuck to my door reminding me about the package. I plucked it off and went inside, surprised to find Vincent there again. I'd figured his angel business would be keeping him busy elsewhere. â€Å"How's it all going?† I asked. I rummaged through my cupboards, looking for food. I'd skipped breakfast. â€Å"I mean, if you can tell me without having to kill me.† He sat at my kitchen table, leafing through newspapers. â€Å"Ah, well, still can't give you details, of course, but I can say that†¦um, well, progress isn't being made as quickly as we'd like. There's leftover lasagna in the refrigerator if you want it.† I opened the refrigerator door. Sure enough. â€Å"Wow. Did one of the angels conjure this up for you?† â€Å"Only if you consider Yasmine's cooking a type of conjuring.† I uncovered the casserole dish. It looked great. There might be magic afoot after all. I put a piece in the microwave and set the timer. Sitting down across from him, I peered at the spread out newspapers and remembered finding them left out the other day. â€Å"You sure like your news.† He grimaced. â€Å"Most of it's depressing.† Glancing at the headlines, I had to agree with him. Murder. Corruption. Theft. â€Å"You hear about the cop shooting the other day?† I asked. â€Å"That one was really depressing.† Vincent turned his attention away from a story about domestic abuse. â€Å"No, what happened?† â€Å"This cop was outside a convenience store and claims someone was inside shooting his partner. So, he ran in, gun in hand, and started shooting. He ended up killing his partner himself.† Vincent frowned. â€Å"Huh. I hadn't heard that one,† he murmured. From the distracted look in his eyes, his mind had clearly latched onto something I wasn't privy to. I gave him a sidelong glance. â€Å"That mean anything to you? Maybe to this mission from God you're on?† His easy smile returned. â€Å"You're good but not that good. You know I can't say anything.† The microwave dinged, and I retrieved my food. As I stabbed a piece of cheesy pasta, I recalled what he'd said about Yasmine's cooking. My curiosity got the better of me. As it often did. â€Å"Vince†¦Ã¢â‚¬  I began slowly, carefully keeping my eyes on my food. â€Å"I know it's none of my business†¦Ã¢â‚¬  He laughed. â€Å"I always love it when people introduce topics like that – and then go ahead and dive in anyway.† Blushing, I shut my mouth. â€Å"No, no,† he said, clearly entertained. â€Å"Go ahead. What were you going to say?† â€Å"I†¦well, nothing really. It's just, I mean, it doesn't matter to me†¦but I just sort of noticed that you and Yasmine seem, um, close.† His levity faded. I quickly looked up and met his eyes apologetically. â€Å"I'm sorry,† I blurted out. â€Å"Forget I said anything.† â€Å"No†¦it's, I don't know.† He folded up the newspaper, staring at it without really seeing it. â€Å"Yeah, I guess. I've known her for a long time, and after a while, it's easy to†¦well, she's easy to like.† â€Å"Yeah, she is.† A few pregnant moments passed. When he spoke again, I heard affection in his voice. â€Å"I first met her at this fair in Akron, of all places†¦about, oh, fifteen years ago. Not sure what she was doing there – you never do with them – but I found her walking away from a concession stand. She had this giant tower of cotton candy. I swear, it was taller than she was. And, since I could tell she was an angel, it made the situation that much more absurd.† The story made me smile too. It also shed light on why he was here with the A-Team. I could tell she was an angel. He was another gifted human, like Erik and Dante, who could sense the immortal world. â€Å"And you went and talked to her?† â€Å"I hadn't planned to, but then the cotton candy started to fall over, so I went to help her and ended up eating half of it myself.† â€Å"That's sweet,† I said. â€Å"Er, no pun intended.† It didn't matter that in the last few months, I'd fucked one guy in an office chair, used a leather whip on another, and gone down on another in the back room of a seedy club. I still loved romantic stories. â€Å"She started asking for my help after that, off and on, once she realized what I could do. It was supposed to just be that†¦nothing more than her, you know, professional cases. But after a while, we couldn't help it. We're together all the time now.† I swallowed another piece of lasagna. It was divine. Seriously. â€Å"Do any of the other angels know?† â€Å"Yeah, right. Joel barely tolerates me now†¦Ã¢â‚¬  â€Å"But obviously, you guys aren't, um, you can't be – â€Å" â€Å"No, but it doesn't matter. It doesn't have to be physical. Really, it's ironic. Angels are creatures of love. They're supposed to love everyone. They're just not supposed to love one person so much more than another.† â€Å"That's stupid,† I stated adamantly. â€Å"To you, maybe. And to me, I suppose. But to her†¦well, she devotes her entire existence to the service of a power and cause bigger than all of us. To be so in love with something – or someone else – is distracting. You can't serve two masters without eventually betraying one.† I looked down again, turning over his words. â€Å"And yet you guys still stay together. Sort of.† He shrugged. â€Å"In as much as we can. Maybe I should move on with my life, but, honestly, there's no one else I want to be with. I accept what she is. It's why I love her. I'd rather be with her in a limited capacity than none at all.† Goosebumps rose on the back of my neck. He'd just stated a variant of what Seth used to tell me all the time, back when I would continually urge him to leave me and find someone else. I'd accepted his choice by now and honestly couldn't imagine not having him in my life. But still. Sometimes I didn't entirely get how he could be okay with everything between us; hearing another person support such a choice was refreshing. As though reading my mind, Vincent gently asked, â€Å"Am I hitting too close to home? Carter mentioned a boyfriend†¦Ã¢â‚¬  â€Å"No. Yes. I don't know. He – Seth, my boyfriend – says the same thing as you. That if it can't be any other way†¦well, then this is the way he wants it.† â€Å"Exactly. And thus, life goes on.† Vincent started gathering up the newspapers. â€Å"I tell you though, I think your side and hers are both so fucked up, it's not even funny. Why the rules? Why does a succubus always have to take away someone's life when she's with them? Why can't you have the choice? And why can't Yasmine make love? Why can't she be in love?† Good question. I don't think Vincent really expected an answer, but I had to give one anyway. â€Å"Because that's the way it is. The way the system works. The way it's always worked.† â€Å"The system is fucked-up,† he said. I thought about it and nodded. â€Å"No arguments.† Smiling, he reached for his coat and slipped it on. â€Å"You're okay for a succubus.† Vincent left, off to do whatever it was one did with a posse of angels. I almost envied him because I had something to do that I wasn't looking forward to at all. It was another necessary evil. I had to get Tawny a job. After that debacle of a dance lesson, I'd told her I'd help. I might not be able to do much about my mysterious energy loss or angelic romances, but I sure as hell could do something to expedite Niphon's departure. I drove down to Seatac, a city that owes its entire existence to the Seattle-Tacoma International Airport. It's more of a shadow, really, spreading around the airport in a blanket of long-term parking lots and cheap hotels. It also has a couple of strip clubs because really, what else are out-of-town businessmen supposed to do in their downtime? It was late afternoon, so business was slow when I stepped inside Low Blow. A few bored-looking men sat scattered throughout the place, which was dingy and in need of some serious redecorating. Or, well, any decorating. A couple of the guys glanced up with interest as I walked through. Apparently, I held more appeal than the poor brunette trying her damnedest to fuck a pole in time to the dulcet sounds of Pink Floyd's â€Å"Young Lust.† I opened my mouth to speak to the bartender, but a voice behind me interrupted. â€Å"Ho†¦ly†¦shit. I don't believe it. I don't fucking believe it.† I turned and looked into the long, narrow face of Simon Chesterfield, the proud proprietor of this dive. Between his face and lanky body, he always reminded me of a weasel. His black mustache never quite seemed able to grow in completely, and he dressed in brand name clothes that were always one size too small. He was chummy with the local Hellish players, and rumor had it he was in line to be an imp, eventually selling his soul for immortality and the chance to be a diabolical salesman. â€Å"You finally come to dance for me, doll?† â€Å"You wish.† For a sleazy guy who ran a sleazy establishment, Simon actually had a legitimate appreciation for dance. I'd once seen him trying to choreograph his strippers and had been impressed by his sense of aesthetics and rhythm. His employees hadn't really caught on. Such talents were kind of wasted here, and I used to wonder why he didn't take his business to one of the more affluent suburbs where he could get a higher caliber of dancers. The reason he stayed, I'd later learned, was that this was a better venue for all sorts of other shady business he conducted. Still, Simon had a sharp eye and knew what a good dancer I was. He'd been on me for years to come work for him. â€Å"We need to talk,† I explained. â€Å"Business.† â€Å"It's what I do.† With a sweeping gesture, he pointed to a doorway beside the bar. â€Å"Let's go to my office then.† His ‘office' was barely a broom closet, but it had a stool for me to sit on. Resting my heels on a mid-level bar, I brought my knees up to my chest. It made my gray linen skirt slide up a bit. Simon watched with an interest that was more professional than personal. â€Å"Fuck, woman. You come dance for me, and I could make a killing.† He shook his head and collapsed into a rolling faux leather chair. â€Å"A succubus on my stage. Fuck.† I tilted my head to the side. â€Å"It's funny you mention that because that's kind of why I'm here.† I think my innocent tone set his alarms off. He eyed me suspiciously. â€Å"I thought you said you didn't want a job.† â€Å"Not me. We just got a new succubus, and she's looking for a gig. Didn't you hear?† â€Å"No†¦Ã¢â‚¬  He frowned. â€Å"And she wants to dance? Here?† â€Å"Yep,† I said glibly. â€Å"She can't wait to take her clothes off.† Wasn't that the truth. Simon leaned back in the chair and put his feet on the desk. Casual pose or not, he was still on guard. â€Å"What's the catch?† â€Å"Why does there have to be a catch? You should be excited about this. We're doing you a favor.† â€Å"You're offering to drop a succubus into my lap. That sounds too good to be true, so it is too good to be true.† He paused, still thinking. â€Å"And why are you here instead of her?† â€Å"I'm altruistic.† â€Å"Georgina,† he said warningly. â€Å"Okay,† I admitted. â€Å"She's kind of†¦new.† â€Å"How new?† â€Å"Really new. Still under warranty.† â€Å"There's still a catch here somewhere.† â€Å"Well†¦she's†¦Ã¢â‚¬  I spun through my mental rolodex of adjectives. â€Å"Inept.† He raised one narrow eyebrow. â€Å"Inept?† â€Å"She's still learning how to get men.† Since Simon probably wanted sexy women working for him, I figured it wasn't worth mentioning that Tawny wasn't so much learning as she was still trying to find her way to class. â€Å"And she's a, um, bad dancer.† â€Å"How bad?† â€Å"Bad.† â€Å"Can you be a little more specific on what level of bad we're dealing with?† â€Å"Remember Gigli?† â€Å"Jesus. So, why do you think I'd want to take on a shitty dancer?† â€Å"Simon,† I exclaimed. â€Å"All your dancers are shitty.† â€Å"Not all of them,† he said. â€Å"And it's not like I'm trying to get more. We have standards.† I gave him a pointed look. â€Å"Alright, alright.† He ran a hand through his gelled black hair. â€Å"What do I get in return?† Now I was the indignant one. â€Å"What do you mean? You're getting a succubus dancer. What else do you need?† â€Å"I'm getting a succubus charity case. I'm the one doing you a favor.† His eyes were shrewd. Yeah. He'd make a good imp someday. He was this close to breaking out a contract. â€Å"I want you. Dance for me two nights this week.† â€Å"No.† â€Å"One night.† â€Å"Simon, there is nothing in this world that's going to get me to dance here, not even a succubus charity case. Pick something else.† â€Å"Okay, fine.† He pondered. â€Å"You. I want you.† â€Å"Hey, I just told you – â€Å" â€Å"No, no. Not as a dancer. As in right now. On the desk.† I sighed. That kind of want. â€Å"Look, if I've gotta hire a bad succubus, I might as well fuck a good one.† â€Å"Interesting logic. Aren't you worried about your soul?† He looked at me like he couldn't believe I'd had the audacity to ask such a thing. It was similar to the look I'd given him when he said Low Blow had standards. â€Å"Noted.† I stood up. â€Å"But not this body. Pick another shape.† Simon snorted. â€Å"You think I'm interested in a pinup girl crossed with an Ann Taylor model? Fuck that. I want a sixteen-year-old version of Liza Minnelli. In a school girl's uniform.† I stared. â€Å"I have no idea what that would look like.† He started undoing his pants. â€Å"You're a smart girl. Figure it out.† Sighing again, I shape-shifted, taking on a small body with a black pixie haircut. Baby smooth skin. Green plaid skirt with matching vest. Simon grunted his approval. Turning, I rested my hands on the desk and bent over, thrusting my ass out toward him. I hoped it would be over soon. If I could just get the weasel comparison out of my head, this would probably be a lot easier. I felt his hands slide along my legs as he pushed the skirt up. Suddenly, he froze. â€Å"A thong? Are you insane, woman?† â€Å"You're a sick bastard,† I told him. The thong changed to white cotton panties. â€Å"Don't I know it.† He pushed the panties down and thrust forward. Well, I guess it was a thrust. Simon wasn't that well-endowed. I was on the verge of saying something like, â€Å"Are you there yet?† Alas, the Tawny situation was too dire. I couldn't risk Simon changing his mind about her for the sake of a joke, no matter how funny. But, whatever Simon lacked in size, he made up for in enthusiasm. He gripped my hips, nails digging into my bare flesh as he pounded away. I had to keep a fierce hold on the desk. Eventually, seeking variety, Simon flipped me over to my back. He unfastened my blouse and bra, exposing small, perky breasts that had just â€Å"blossomed into womanhood.† Eyes on them and not my face, he grabbed my legs and spread them so that my ankles practically rested on his shoulders. He returned to the task at hand, and when he finally came, I have to admit I welcomed the energy burst. It wasn't a lot – the guy practically worked for Hell already – but I needed it. Simon pulled out of me, and I sat up, mildly sated from an energy standpoint, if not a physical one. I honestly hadn't done much but lie there the whole time, but he regarded me as though we'd just gone through the entire Kama Sutra. â€Å"Definitely worth putting up with an inept succubus,† he said happily, pulling his pants back up. I wanted to say that he might want to withhold judgment until he actually met Tawny, but instead, I just smiled. I knew when to keep my control switch on.
