Jennifer smiled down at me as she removed her coat. She was naked underneath the short black dress, apart from her garter belt and thigh-high stockings, her long legs tapering down to a pair of high heeled boots.

"Do I look good?" she asked.

I couldn't really reply intelligently as my mouth was wedged open with an O-ring. My head was locked in a box with a hole for my face to fit through, doubling as a low seat and wrapped in tight fitting clear plastic saran wrap with a mouth hole. My arms, legs and torso were bound tightly to a board beneath me.

She moved in and out of my restricted field of vision, giving me a glimpse every so often of her tan thighs, framed by the dress hovering seductively on the edge of something more.

She placed one boot on the side of the box that was my prison, affording me a clear view of her tight ass and shaven pussy. I could do nothing but stare, my cock slowly rising to an erection. She leaned over as my member engorged itself and wound a rubber band around the skin between my testicles and penis, making certain that I wouldn't be coming anytime before she allowed it.

My erection stopped growing in protest. She laughed and straddled the box, lowering her pussy so that it barely touched my captive mouth. She hovered there, letting me breathe in her moisture, touching my plastic wrapped cheeks with her buttocks in slow soft circles. She was doing this for a reason, and it worked.

Against my will, my penis steadily hardened until it was rock-hard and aching. Jennifer suddenly lifted off my face and, lifting the lid of the box, placed another sheet of plastic film over my face, before closing the lid again so that it anchored the plastic over my mouth. As I began struggling for air, she quickly moved to my hips and straddled my penis, sliding her willing cunt down my length in one movement. She began massaging my cock with her inner muscles while I sucked uselessly against the plastic, writhing in panic underneath her.

She began fucking me earnestly now, checking to make sure I hadn't passed out. Her pussy quivered and pulsed on me, hot and wet and grasping. My cock responded to her, wanting to come, but incapable of doing so. Instead it throbbed inside her as she began coming on me, juices leaking from the lips of her orgasming cunt down my rod and onto my tied-off balls. She shuddered and shook on my weakening form and then pulled the plastic away, allowing me a huge gasping breath.

It was clear to me now that this was simply a way of saying that she was in control and that my usual desires and wants were of no importance to her. I was there only to pleasure her and, if I got anything out of it, well – that was pure coincidence. My mind was filled with a red rage, furious that I was of secondary importance here.

She disengaged herself from my cock and, moving back to the box, straddled my face again, this time facing my head. Her pussy was pink and swollen from the sex with a line of moisture outlining the slightly parted lips. She brushed it against my tongue a few times and then moved forward, settling her ass on my mouth. I knew without bidding that she wanted my tongue. I carefully extended my tongue into the crevice between her cheeks and licked her anal rim. Slowly, her tight hole opened up to my tongue and I slid inside, licking the inner walls, feeling her muscle squeeze my tongue rhythmically as it went deeper. I prayed that nothing would come out of that hole. I was still recovering mentally from the last experience. The reality had turned out to be a far cry from the fantasy, disgusting, unpleasant and embarrasing. She seemed content to just let me lick her, though.

After a few minutes of this, she shifted position and pushed her pussy into the ring that wedged my mouth open. I thought she was going to wet herself on me then, but she just let me lick her, moving her hips against me and smothering me with her slowly swelling cunt. I couldn't breathe, but figured if I could make her come it would all be over. I began tonguing her as skillfully as I could, trying to coax the orgasm that I knew was there. She rewarded me with a short breath before sitting back down on me and pushing her wet pussy harder against my questing tongue.

I felt her movements quicken and knew she was about to come. I laid into her for all I was worth, flicking my tongue against her clit and shoving it inside her alternately. Her hands came down and grabbed the edge of the box, pulling herself down tighter against me, sealing herself to my mouth. The pussy above me convulsed once, fluttering on my tongue, and then began a series of shuddering contractions, her ejaculate flowing onto my tongue and down to the back of my throat.

She slowly came down from her orgasm and lifted herself from the box. She bent down and lifted the lid, rasing my head from the box to pull the plastic off and remove the O-ring.

"Don't worry," she said, "you'll be getting that back later!"

She wiped my face dry and secured several strips of duct tape over my mouth, ensuring that they were tight, then closed the lid on my head again and, releasing the elastic on my balls, left the room.

I lay there for what seemed like hours, although in reality, it was probably a few minutes. I could hear the sounds of a porno playing on the TV as Jennifer worked herself up for the next bout.

Eventually, I heard the sounds of her coming back down the passage, but this time it sounded like there was someone else with her. She walked into the room and immediately straddled me, stroking her wet pussy just above my gagged face. I could see nothing except Jennifer's thighs and pussy, but I heard someone sitting down against the wall. No words of explanation were offered, just the continual stroking of the threatening pussy that hovered above my face, like an animal waiting for the kill, her scent filling my nostrils and dulling all my other senses.

Slowly the pussy descended and covered my face, my nose sliding into her, the puckered asshole coming to rest directly above my eyes. I began to panic as her weight settled on me and her pussy rubbed back and forth against my nose. She was hot for it and her cream oozed slowly out of her pussy as her excitement grew, her ass cheeks rubbing it into my eyes and blurring my vision. The fact that there was an audience turned her on even more and heightened my embarrassment. I was desperate for breath now, bucking and snorting underneath her, but the bonds tying me securely to the board allowed no movement at all. Seeing my discomfort, she humped harder against my face, her legs gripping the edge of the box tightly as she peaked towards her cruel orgasm.

Everything began to feel warm and fuzzy as I stared up into the blurred mess that was Jennifer's ass. I felt weaker and weaker and my struggles were starting to fade. I tried weakly to mumble something like "help", but it just came out as a dim muffled noise against her asshole. Hearing this pushed her over the edge. Her ass cheeks shuddered down against me and my face was suffused with heat as her pussy muscles ballooned out against my nostrils and pumped wad after wad of her cum down into my numb face. Her hands came down around my neck and, as the pussy slid and jerked against my face, I passed out underneath her straining, tight body.

When I woke up, Jennifer had removed the tape and was busy wrapping my head again. Once my head was tightly wrapped in plastic, she forced a hole through the plastic and pushed the ring into my mouth, fastening the straps around my aching head.

She disappeared from view and I could faintly make out gasping sounds through the layers of towelling inside the box. Every now and again a soft sucking wet sound was audible followed by moans and gasps. This carried on for a few minutes. I was frantic trying to figure out what the hell was going on, but nothing was said. Suddenly there was a high keening sound followed by the sound of Jennifer saying "fuck, fuck, fuck....yeeeees!". Then there was silence. I realised she must have been using a dildo to bring herself to orgasm.

Suddenly, Jennifer's butt was back over my face. I could only make out the rough shape of her through the plastic, as she had not made holes for my eyes this time. Her pussy slowly came down towards my open mouth and I extended my tongue. As I touched her swollen cunt, I knew there was something different this time. I heard her cruel laugh just before I tasted the semen inside her. I shouted my anger, then her pussy covered my mouth, cum leaking out of her onto my now retracted tongue, slowly filling my mouth. Her wet thighs slid down either side of my face and settled down, gripping tightly against my cheeks. She slapped my chest, making it sting. "Lick me!" she commanded. She slapped me again and I slowly extended my tongue into the slippery mess, pushing up inside her, opening her fucked pussy. The come began to trickle steadily out of her and, as I pulled my tongue out for an instant, a rush of jism filled my mouth.

She lifted up and stared down between her legs at me choking down the cum, bubbles of semen forming where the ring forced my lips open. Her breathing starting to get heavy and she sat back down forcefully, ramming her pussy into my mouth, with my plastic-covered nose poking against her asshole.

I began licking her twitching pussy through the mouthful of cum, trying to give her an orgasm so she would let up. Her hands grabbed my neck to prevent me from swallowing too quickly and she began to fuck my captive face, her pussy bulging into my open mouth each time her hips thrusted. There was a tension I couldn't quite make out in her. It wasn't just the need for orgasm, there was something else. Her pussy forced its way into my mouth one final time, so deep the lips were touching my inner cheeks, then it began to spasm again in my mouth, her orgasm taking hold of her.

I didn't know that she had been holding herself for most of the day and had been on the verge of wetting herself when she walked into the room. In the midst of her throbbing wet orgasm, her bladder control failed and a hot stream suddenly sprayed out of her, rapidly filling my mouth. I was shocked and scared shitless! She knew it had been a while since my last breath. If I lost consciousness or ran out of air, I would drown... Reality cut off my thoughts and I began swallowing as fast as I could. Jennifer bucked and moaned on top of me, still having her huge orgasm and spraying urine into my captive mouth, her ass pulsing softly against my nose. As I choked down her foul-tasting piss and cum mixture, my tongue swiped involuntarily against her pussy lips, the extra stimulation making her come even harder on me. She was pumping so hard, I thought my nose would break under her spasming asshole. She released one last burst of hot piss into my mouth and pulled off briefly, pulling her ass cheeks wide open, then settling her ass against the ring in my mouth, letting go so the cheeks settled firmly against my face.

She sealed my mouth so firmly that it created a vacuum. Try as I might, I couldn't swallow the mouthful of pee. Each time I tried to swallow, my tongue pushed outwards, touching her expanding ring.

"Put it in!" she ordered.

I extended my tongue and slid it into her wide open asshole. She wriggled on my face, feeling the tongue slide deep into her ass. The hole began trembling on my tongue with a terrible intimacy, the muscles spasming uncontrollably. She lifted a little from my face, keeping my tongue inside her ass. I swallowed and snatched a breath before she sat down again, her asshole straining wide open, allowing my tongue even deeper. As my tongue explored her butt, it suddenly hit a soft mass. I tried to scream and struggled madly against my bonds, attempting uselessly to close my mouth. Jennifer sighed happily and bore down on my face, her ass expanding a little more on my tongue, then the shit came out of her, landing against the back of my throat. I pushed my tongue back against her ass, hoping to give her pleasure. As she began masturbating furiously, it opened again and another soft mass spilled into my screaming mouth, rapidly filling it until it overflowed and she had to lift from my face to finish it...
