Desc: Science Fiction Sex Story: Chapter 1 - When Robert's coworkers play a little joke on the introverted young man and give him a shemale hooker for his birthday, nobody could anticipate the end of the world...Well, it doesn't really end, exactly, but people are definitely inconvenienced.

"Happy birthday, Bobby!"

"Uhhh..." I blinked at the young woman who'd knocked on my door, taking in her long legs, large breasts, and pretty face all at once.

"You are Robert..." she asked with a smile. "Right?"

"Yeah," I agreed, barely able to get the word out. I'd never been much for talking to any girl, but especially not the attractive ones and she was beautiful.

"Well," she widened her sky blue eyes and offered me a shrug of her slender shoulders, "I'm your birthday present."

"You are?" I could see her nipples, dark and prominent through the pink halter top she wore. The creamy tops of her breasts were exposed, the deep cleavage between them almost mesmerizing.

"I guess you work with some pretty nice guys," she half-explained. "Can I come in?"

"Uh, yeah ... Um..." I dropped my eyes, feeling somewhat foolish, and drank in her wonderfully smooth thighs.

She wore a black miniskirt and matching heels, and even from that angle, I could see the sculpted muscles of her calves. She had legs like a dancer and I suppose one could say I was a leg man. A foot man too as I admired her red painted toes. I loved open toed shoes, especially the ones with 3 or 4 inch heels and a gorgeous woman wearing them.

"I'm Shelly," she told me, tossing her thick, blonde hair from one shoulder to the other as she looked around my small apartment.

"Robert," I replied, and then winced when she giggled.

"I know," she reminded me. "What do you like?"

"Uh..." I narrowed my eyes as Shelly stood in the middle of the living room. She slipped her purse off her shoulder and dropped it on my old recliner.

"Your friends paid for two hours," she informed me. "Anything you want."

"Anything?" I swallowed hard and she nodded slowly, playing her pink tongue between her crimson lips.

"Oral ... Anal..." she suggested. "Do you want to go down on me?"

"Maybe?" I replied, not intending to make it sound so much like a question.

"Don't worry," she said, stepping close and putting her hands on my shoulders. "I've been with guys like you before, Bobby."

"L-L-Like me?" I stammered. "You have?"

"Uh-huh," she sighed, looking down as Shelly must have been several inches taller than me. Her high heels only made me feel that much smaller.

My cock began to harden as the surprisingly elegant smell of her perfume filled my nose, or maybe I'd been hard already. I couldn't seem to remember as I took a deep breath and somehow found the courage to touch her hips with my fingers. She had a very pretty face, with high cheeks and a generous mouth that seemed almost too large, but not when she smiled. Her eyes were fixed on mine and it seemed a moment of intimacy like I'd never experienced before in my life.

"You're a virgin, aren't you?" she asked, smiling at the look on my face, a mixture of shame and guilt, and surprise that she could know so much about me.

"I just never, uh ... met the right girl," I told her, offering Shelly the same old excuse I gave my mother.

"It's alright," she whispered. "I'm going to change that, Bobby. I promise."

I'd heard someplace that most prostitutes don't like to kiss their customers, but she kissed me. I closed my eyes and held my breath. When Shelly's tongue parted my lips, I surrendered completely. My hands tightened around her slim waist and I could feel her firm, upturned breasts rubbing against my chest. We were fully dressed, just standing there and making out like teenagers. Her tongue seemed to fill my mouth, light and delicate and fluttering over mine. It was the best moment of my life, all twenty-five years of it. Twenty-six, now, I reminded myself.

"Where's your bedroom?" Shelly breathed, pressing her mouth to my ear as we hugged. She rocked her hips, grinding against the now obvious erection tenting my trousers.

"That way," I answered, letting her take me by the hand like a little boy. I would have followed her anywhere.

She undressed me first, neither of us saying a word, and I'd never imagined having a goddess like Shelly on her knees, but there she was. Still fully dressed in her top, skirt, and shoes, but kneeling on the floor of my bedroom and smiling up at me as she pulled my boxers down. I'd be lying if I said she was the most beautiful woman I'd ever seen, but just then I couldn't have admitted otherwise. I thought she looked amazing and I braced myself as my penis sprang free, very nearly slapping her on the chin.

"Ohhh..." Shelly breathed. I'd been expecting her to laugh because I knew I wasn't very big down there.

Whatever her private opinion of my modest manhood, she made me forget my embarrassment. Shelly tickled my thighs with her red fingernails and kissed the tip of my penis, wetting her lips with precum before opening her mouth and taking me inside. The first blowjob of my life was truly indescribable, as I'm certain it must be for most men. The sensation of her soft, wet mouth seemed very different from anything I might have imagined. Like making love to a cloud, that's the best analogy, and I never wanted her to stop.

"Don't cum yet," she whispered, licking her lips and looking up at me after only two or three minutes of sucking.

"I'm close," I admitted with a hard swallow, feeling her blonde hair tangled around my fingers. I'd been afraid to hold her head at first, but Shelly hadn't stopped me, and there really hadn't been anything else to do with my hands.

"Lie down," she suggested. "I want to give you a massage first. You're so tense!"

She giggled and I wondered how I could be anything but tense, having been brought to the edge of orgasm like that. I thought I understood what she meant, though; I did need to calm down, but I hoped the massage wouldn't take too long. I only had Shelly for two hours and half an hour had already passed. It wasn't in me to argue with her. In fact, I probably couldn't have summoned the strength to disagree with her about anything. I didn't want to.

I laid down on my bed, on my stomach as Shelly removed her shoes and pulled her halter top over her head. Her breasts were too good to be true, and by that I mean they must have been fake, but they were flawless and breathtaking all the same. She had impossibly firm, round tits with very dark nipples pointing outward invitingly. They seemed to be begging for a kiss, but I only stared at them until she moved out of sight behind me.

The bed moved, the springs squeaking softly as Shelly got onto it a moment later. I assumed she'd taken off her skirt, perhaps even her panties, and I began lifting my head to look over my shoulder, but she stopped me.

"Shhhh ... Just relax," she said. "I'm going to make you feel good now."

"Mmmm..." I sighed in agreement as I felt her knees straddling my thighs, her calves teasing mine as she knelt above my prone form.

"You're nice and clean," she told me. "I like that in a man."

"I take a bath every ... Oh!" I gasped as she kissed my shoulder.

"You're sexy too," Shelly whispered, half-giggling and squeezing my butt cheeks with her hands. "Such a cute little ass, Bobby."

Her hands played with my butt for a moment while she continued to kiss and nibble at my shoulders and neck. I wasn't sure what to expect, but Shelly wasn't giving me any sort of traditional massage. She didn't rub my back so much as slide her hands upward and hold my shoulders down. As I mentioned, she was a tall young woman, with an athletic figure despite her large breasts. The rest of her had a naturally lean, well-toned appearance like those girls who play soccer or beach volleyball. It's a look I admired greatly and Shelly's hard, tight body covered mine easily with her knees outside my hips and swollen nipples teasing my sensitive flesh.

"Uh! Ow! Hey, uh ... Ugh?! Ouch!" I gasped as I felt something stiff, blunt, and decidedly large pressing between my cheeks and against my anus.

"Don't fight it," Shelly breathed, grabbing my wrists with both hands and jerking my arms towards the headboard.

"What ... No! Oh ... Ahhh..." I winced and jerked beneath the ... woman? She had a cock!

"Let me inside, Bobby," she cooed. "Let me fuck you nice."

I struggled to get out from under her, to escape Shelly's grasp, but it was useless. Her breasts were flattened against my back as her weight pushed me into the mattress. She didn't have a lot of fat, but muscle is heavier anyway, and the woman was very strong. She held my arms easily despite my efforts to break free of her iron grip. I kicked my legs, but that didn't help at all. Lifting my hips and trying to buck her off proved a mistake as my rectum contracted and relaxed, giving her a golden opportunity to claim my precious virginity.

"Noooo..." I groaned, feeling my eyes growing wet with tears of frustration more than pain, although it did hurt quite a lot in the beginning.

"Yeah! Nice ... and ... tight!" Shelly said, grunting the words with unabashed joy. Her pleasure at raping my reluctant asshole only made my humiliation that much more complete.

My anus had been torn open, I feared, ripped by the blunt, obscene pressure of her cock spearing into my bowels. Shelly would push with constant pressure while I clenched my ass and tried to keep her out. I couldn't keep that up, however. I had to relax eventually, if only to breathe, and after half a minute or so she gave me a sharp, hard jab of her hips and stole another inch or two of my burning ass.

By the time she'd gotten all of her cock inside me, I'd surrendered completely. I sobbed like a little girl, trembling and too weak to fight her any longer. Shelly slid her excited prick back and forth easily, fucking me at a steady, deliberate pace. Her precum must have been providing all the lubrication she needed and the sharp burning soon gave way to a dull throbbing sensation that might have felt good under other circumstances.

The slapping of Shelly's body against mine filled the room. I could feel her heavy, sperm-filled balls every time she drove the full length of her cock inside me. She held my shoulders, pulling me back as she lunged forward, but even with my arms free I was helpless and we both knew it. She fucked me like a bitch, telling me how sweet and sexy my asshole felt wrapped around her prick. Shelly even kissed me, nibbling my ears and licking my cheeks, moving faster as the minutes passed. How long she raped me, I honestly had no idea.

"Ummmm ... I'm cumming ... Ohhh..." she sighed. "Feel that? I'm cumming inside your ass, Bobby!"

I didn't say anything, but I was definitely aware of the semen flooding my bruised rectum. Shelly's cock seemed to pulse inside me, joining us so intimately in that awful moment of truth that we may as well have been a single person. I felt her ejaculation like a second heartbeat deep in my gut, the spasms receding only slowly as her cockhead caressed my prostate. That had been the only pleasure I'd found in the entire degrading experience and it meant very little. My cock wasn't erect beneath me. I felt nothing except guilt and shame, not even anger.

I'd been raped and I wept as Shelly pulled her cock slowly from my ass.

"You're a great little fuck, Bobby," Shelly said, kissing my tear stained cheek. "Look me up sometime, okay? Happy birthday!"

I kept my eyes closed as she left with a giggle. I lay there all night without moving except to curl up on my side and hug a pillow. I slept occasionally, but only fitfully and then cruel dreams assaulted my subconscious. Dreams of Shelly and her cock forcing its way inside my body. I'd wake up sweating and breathless, with my eyes wet and my ass throbbing painfully. Her cum had begun to leak from my stretched anus and it felt cool and greasy on my skin. But I didn't get up or try to clean myself, not until the alarm clock forced me to make a decision.

I had to go to work.
