The Lab Assistant (16 page)

Not too fast.
I wanted to savor this lovable young girl. She smelled sweet and musky, freshly fucked, with a sharp bleach-note of come. As my tongue touched her tender, delicate asshole her entire body tightened and shifted back against me. Her body, her asshole, begged to be tongue-fucked. Her orifice winked open for me and, as I extended my tongue, she rocked back against me. A thick drop of juice rolled onto her clit, and fell to the floor. Inside my body, a deep, dull yearning threatened. I needed to come.

"I love your tongue," she breathed, the side of her face grinding into the floor. Two of her fingers snuck back and rubbed quick, desperate circles against her clit.

I felt a strange confluence of feelings--intense arousal, pleasure, lust, but at the same time an unfamiliar yet nagging sense of infidelity.
This was okay with Sonia
, I knew. She was on the other side of this very room getting taken by a group of men, taking two of them into her rectum at the same time. This was about exploring our love, I knew. But, still, some small part of me wanted only her. This mix of emotions confused me.

Theresa pressed her ass further up toward me, my head locking between her thick, meaty cheeks, and she reached back to hold my head firm against her asshole. "Jesus Christ, Dr. Corbis. You are
so
fucking good at that! Eat my asshole, professor. Bite it, if you can. Hurt me. Make me hurt when I come."

Sonia's okay with this
, I repeated to myself, over and over, and then nuzzled deeper against Theresa's musky hole.

She bucked back against me violently, so much so that it was beginning to hurt in the back of my neck. "Fist my asshole," she begged. "Shove your hand up my ass."

What the hell am I doing?
I suddenly thought.

"God, hurt me!"

"Theresa, are you sure?" I said. I lifted my head from her sex and looked over her cheeks to Sonia. She couldn't see me; she couldn't see anyone, half a dozen men crowing around her, their cocks inside her, on her, beaten above her. It was madness, like a feeding frenzy.

"Dr. Corbis!" Theresa was insistent, desperate.

"Yes," I said, returning my attention to her.

"I want to feel like I'm being torn apart. I wanna push it. I wanna see what my asshole can take. You're making me feel so, so good. God, I want to feel like my hole is being torn open! Show me what my body can do."

"Okay," I said finally. I had no idea what to make of her. Who was this crazed woman? Where did this kind of need come from? She certainly had never betrayed any of this depravity in class.
Jesus, look at that ass!
I'd never done anything like this.

"Go slow at first," she directed, wiggling her experienced ass at me. She laughed. "And not your
actual
fist. Just put your fingers together, and then just slide it in."

I made a cone of my fingers and began to insert them into her ass. As I got to the second knuckle, she screamed and cried, fighting to force her ass onto my hand.

"Yes. Don't you stop! I can take you. Diwaine's already opened me up for you."

I squeezed my fingers and knuckles up inside her. What was driving this desire, I had no idea. As the second knuckles cleared her sphincter, I was met with a dense, heavy resistance. It was as if I'd reached the depths of her bowels, as if she could accommodate no more. I felt as though I was hurting her and I didn't like it.

"It's not going to work, Theresa."

"C'mon, Dr. Corbis," she moaned, and pushed hard against my hand. My fingers eased further, ever so slightly, into her rectum.

"We've got to work up to it." She took my hand, but it felt too much for me. She could take it, but I had to admit that I didn't think I could. This was too much.

"No," she said, her voice torn in desperation. "You just have to push slowly. I can take it. I've done it before. Just slow, constant pressure."

I could feel her sphincter dragging against my third set of knuckles, and I spat a continuous stream of saliva to lubricate her tender opening. But as much as I tried, it just didn't feel right to me. She was some sort of a sexual
fakir
, but I wasn't. Her anus was distended in a vast, sexy gape. It was all too intense for me.

I can't do this.

"Theresa, I can't do this," I said. Having eased my hand carefully out of her ass, I quickly dropped my face between her shaking ass-cheeks. She moaned and cursed. I licked around her still-open asshole and flicked my tongue as far as I could inside her. I could taste the sweaty musk of her anus.

"Dammit, I want to feel it," she cried. "I want my
ass fisted
."

"We can work up to it, I guess," I said, although I had no idea whether we could. I'd never done anything like this. For all Sonia's and my games, we had never approached something like this. I was scared that I would damage her--perforate something. The possibility seemed real despite her impassioned pleas.

She shook her head dejectedly.

"We can get some more lube. We can try to work up to it." I nuzzled my nose inside her ass while licking at her dripping, engorged cunt. "You can teach me how to do it. I'm just not ready right now."

Soon her soft sobs became pleasurable moans, and then ecstatic cries.

"Can you fist my pussy, baby?" she breathed. Her head was pressed to the floor, her eyes a bleary mess of sweat and tears and mascara. She stretched an arm underneath her body and eased apart her labia with two fingers.

I didn't answer directly, but eased first two fingers, and then three, into her wide, sloppy canal. She felt so warm and gooey to the touch! I could feel my cock straining even more than usual. It occurred to me that I could probably come simply from fingering this young girl's cunt, so intense was the tactile feeling of her sex.

I loved Sonia's vagina, but Theresa's seemed somehow more gratuitous and slutty. Her pussy was meant to be fucked, sucked, licked, and abused. It wasn't a birthing canal, it wasn't there for any other purpose. It was a cock canal. It was there to come and make come. And this young girl's appetite inspired me.

"Hurt me," Theresa pleaded.

"Why are you doing this?" I couldn't understand her. "Theresa, why do you need to hurt?"

"Please, Dr. Corbis, just do it. I'll make you come."

I turned my hand around on her sex and gently sank four fingers inside her. My thumb prodded and massaged her anus as I worked her womb, and this caused her to moan and gyrate softly under my touch. I moved beside her and reached my free hand to her head. Tenderly, I caressed her hair and the side of her face. She turned to me and licked her lips slowly. I traced my hand down her face and onto her neck and gently wrapped my fingers around her.

She moaned, "Uh huh," and I tightened my grip on her throat.

This, and my fingers punching hard into her cunt, made her shriek with pleasure. I squeezed harder, feeling my fingers constrict harder on her windpipe. A strange, contented gurgling escaped her pursed lips.

"Do you like that?" I asked. I could scarcely believe what I was doing.

"Yes," she hissed through my grasp.

I pulled my fingers out of her vagina and slapped her hard on her ass. Her weighty, doughy ass-cheeks jiggled heavily. My cock strained. Again, I struck her ass, harder this time, as hard as I could. My fingers imprinted as five large red welts on her soft skin. My fingers stung, badly. The pain lingered.

What the fuck am I doing?

But she moaned and writhed and pushed her ass toward me, arching her back, lifting herself up to spread her corpulent cheeks.

I hit her again, on the other side of her ass, and she cried out.

As the stinging slap subsided, I could hear Sonia. She was coming. She wasn't speaking, wasn't able to around the cock shoved deep down her throat, but I could hear the noises she was making. I slapped Theresa again, even harder. Quickly now, I pumped my cock with my soaking wet hand. Theresa's juices dripped onto the floor. I slathered them up with my hand and then smacked her again, several times, progressively harder, until her glorious white skin was tinged pink and blood red in places.

Theresa collapsed onto the floor with a heavy groan, her head tilted to the side to watch me. Her face contorted with pleasure, pain, and lust. She breathed hard, labored, like a wounded animal.

I stared at her blankly, as if she wasn't really there, as if I wasn't really there--somehow detached, out of body. My cock throbbed in my other hand, my heart pounded, and my ears filled with the roar of blood. I grew lightheaded. I was possessed.

She wants this
, I thought to myself. It was justification.

It was the only thing in my mind I was conscious of.

Theresa eased her ass up off the ground and pointed it toward me. "More," she pleaded. "You have to finish me."

I pressed the whole of my hand along her silken vagina, and then curled my fingers under, slipping four fingers inside her hungry sex. She was surrendering everything to me, and her passion and need had overwhelmed me. As I sank further inside her, I twisted and squeezed at her throat.

Within seconds she tripped on the cusp of a violent orgasm. I could feel her vaginal muscles pulsing and contracting against my hand, and I could detect a heavy, uneven pulse in her neck. I plunged my hand inside her at an ever-increasing rate, twisting and turning within her sopping cavern. And I squeezed, and squeezed.

And squeezed her throat.

"Oh, Coop," she whimpered, her voice little more than a gurgling, gagging cry. She shifted her weight under me and managed to extend her arm toward me. I could feel the fingers of her hand grasping my cock. Slowly, she began a series of short, heavy strokes. She had limited range of motion, but she expertly masturbated me in her hand and against her sweaty, soft body.

I became lightheaded again. An intense, visceral feeling suffused my loins. The image of this beautiful young girl laid out prone before me, my fist up her cunt and my other around her throat, drove me wild. The sensation her wet, fat skin created as she ground the head of my cock into the side of her tummy proved almost more than I could handle.

I continued pumping my hand into her womb. Finally, she collapsed flat on the floor under me, crying out, gasping, as the orgasm washed over her.

When the storm of pleasure subsided, she slowly maneuvered herself off my hand and slid out beside me. Her neck sported an inflamed series of finger-like bruises.

Oh, God.

When I saw her, I knew I'd gone too far. The marks looked like wounds. Great, red, hurtful wounds. I swallowed hard and rubbed the back of my head. What had I done?

"Amazing," she moaned. "That was the most intense orgasm I have ever had!"

I stared at her in silence. Somewhere behind us, I could hear Sonia's soft, plaintive mewing. Keeping time, in between her gasps, I could hear flesh slapping against flesh. It was distant to my ears, abstract. I was aware of it, but couldn't really process what was happening.

"Dr. Corbis," Theresa asked, "are you okay?"

"I hurt you," I said. "I mean, fuck, look at your neck, Theresa. Jesus, I was too hard. I
hurt
you."

She turned on her wet, sloppy ass-cheeks and sat up in front of me, her hands reaching out and grasping my own ass-cheeks. Without a word, she pulled me toward her, plunging my rock-hard cock into her throat. Not just into her mouth, but down into her throat. I watched her in silence, allowing her to control my body. One moment she was sitting in front of me, eyeing my cock with her bleary and mascara-run eyes. The next moment, she'd impaled herself on my cock, down so her nose banged against my pubic mound and I could feel her tongue licking the bottom of my balls. My head swam.

Guilt. Bliss. Pain. Ecstasy.

What's happening to me?

When Theresa pulled her head from my cock, a long thread of slimy saliva trailed from the top of my cock to her pursed lips. She gasped slightly, and then threw herself around my sex again. Over and over, she repeated this, growing ever more violent. Thrust after thrust, the intensity of the feeling built in my core. I was getting close.

She pulled me from her mouth, belched a choke, and then cast her throat onto my shaft again. I had lost control.

"I'm gonna come, Theresa," I moaned.

Her only acknowledgement of this was to sink my cock deep into her throat again, where she hummed and jerked her whole throat and mouth around me. As she reached over and squeezed my balls, I could no longer hold back. I blew my come into her mouth. I came with such force that the first two spasms occurred without the familiar pleasure of orgasm. It was mechanical, animal. She milked me with her mouth and tongue until the intense spasms subsided. The pleasure caught up to me, and I literally fell to my knees in front of her.

We leaned against each other, exhausted, kissing passionately. I could taste myself in her mouth, although most of my come was down her throat. I tore and gnashed at her breasts, pulled on her nipples, ground her fleshy mounds flat against her ample torso.

The girl was unstoppable. "Fist me again," she pleaded, "I'm ready for it now."

She leaned back onto the floor, her legs lifted to the side and her large, wet cunt splayed open. She tore at her breasts, pushing them together as I had done, rolling them around in her hands and against her body. I reached across her and pinched her nipples in my fingers. I pinched hard, not like before. The pressure made her wince and cry out.

"Oh, fucking God, that feels good." She licked her lips and stared at me longingly. Her nipples were hard, purple knobs. "Fist me."

I took her nipples in my hands again, squeezing each between by thumbs and index fingers. As she squirmed under the pressure, I twisted the nipples as hard as I could. They stretched and grew black-blue in my grasp. I would stretch and pinch as hard as I could in one direction, then let them loose, only to twist them as hard as I could in the other direction.

What am I doing?

I could tell it hurt her immensely, but she ground her ass into the floor, inching her yawning cunt toward me.
