Face down and ass up, with a 15 inch futanari cock laying in between my cheeks like an oversized hotdog in a bun. This was the situation I had found myself in after accepting a mysterious job offer to be a “research assistant”. It hadn’t been more than an hour since I was interviewed for the position, but I had accepted their request that I start immediately because of the large salary on offer. Now I was trapped inside an underground apartment with a futanari that had already forcefully claimed my throat and was intent on doing the same to my virgin asshole.
I looked over my shoulder, taking in the sight of her standing over my backside. Her massive form seemed even larger from this angle. Her hands reached forward and gripped my ass cheeks, pushing them together around her girthy shaft. “I can tell this ass is gonna feel real good…” she muttered as she removed one hand and used it to grab a bottle of lube from the nearby bedside table. “Just relax and let Big Momma take care of you” she said reassuringly as she squeezed a bit of lube onto one of her large fingers.
I gasped as I felt the cold touch of the lube on my asshole, The sensation of her massaging my puckered hole caused a shiver to run the length of my whole body, and as I started to loosen up she took advantage of this by quickly inserting her whole finger up to the second knuckle. The sudden invasion caused a sharp spike of pain and my anxiety increased, knowing that the finger was nothing in comparison to what was to come. Sheila was apparently unsatisfied with the lubrication her finger had provided, because she then took the entire bottle of lube and inserted the tip of the nozzle into my butt and squeezed, flooding my ass with the clear slippery liquid. “That’s better!” she exclaimed before giving my asscheek an affectionate slap. “Prolly bout as good as it’s gonna get”
Finally, she decided it was time and lined up the head of her behemoth cock with my hole. As she gently pressed the tip against me she placed a hand on my back and pushed down, forcing me to arch my back görükle escort even more. My ass rose higher, while my tight and bloated belly pressed down into the soft sheets beneath me. I looked back over my shoulder, and observed her gargantuan form towering over me. Her breasts and belly jiggled slightly as she moved herself into position, causing my erection to twitch. This reminded me of how turned on I was and helped to calm my nerves as Sheila’s python approached my backdoor.
When the tip of her cock finally made contact with my puckered hole it seemed near impossible to think that it would ever fit inside, and yet her insistent pushing slowly started to yield results. I relaxed as much as I possibly could, and grit my teeth as I slowly stretched open. Sheila moved her hands from my hips to my shoulders, and began to push more forcefully as her patience grew short. “Just a little further darlin’, I almost got my head inside” she muttered before giving a short thrust with her hips, sinking the last inch of her glans inside of me. I felt my sphincter snap down around the shaft of her cock as it slid past the final ridge, and I breathed out a sigh of relief. The pain was still intense but I could already feel my body responding to the pressure being exerted on my prostate, and I knew that from here it would only get better.
Twenty minutes went by, each one feeling like an eternity as she sank the rest of her giant cock inside of me. Each vein felt like a mountain as it passed inside, and each twitch of her erection sent vibrations through my entire midsection. Once fully sheathed, she paused her movements. “You’ve got one of the best asses I’ve ever had, that’s something to be mighty proud of” she said to me, giving my ass a light slap to punctuate her statement. Surprisingly, I found myself swelling with a sense of accomplishment at her praise. While my treatment had been rough, I couldn’t deny that I was warming up to the current situation. Her heavy balls pressed against the back of my thighs and her plump belly bursa eskort rested on top of my butt providing an oddly comforting feeling, and while the pain of her gargantuan member inside of me was still very much present it was accompanied by a feeling of fullness that was very satisfying. I tried to respond to her earlier comment, but all that came out of my mouth was a muffled groan of pleasure and some drool.
Sheila didn’t wait long after that to continue her demolition of my virgin butt, only making a quick adjustment to her position before starting to thrust. She leaned over me and wrapped her arms under my stomach, allowing her heavy breasts to envelope my upper torso, and then started to slowly pull out her length. Once about half of it had exited my body, she slowly reversed direction and sheathed herself in me once again. This process repeated, each time increasing in speed until the thunderclaps of her hips connecting with my cheeks echoed through the room. The impact of her thrusts launched me forward, but with her arms locked around my midsection there was no escape from the ongoing brutalization of my intestines. I was trapped under her plush body, with no choice but to weather the storm.
Pleasure and pain assaulted my mind, each feeling so intense that I found my eyes rolling into the back of my head as my consciousness failed me. I repeatedly passed in and out, sometimes finding myself in completely different positions upon waking. I couldn’t tell how long this went on for, but when I finally awoke for the last time I was lying on my back staring up at Sheila. Her breasts swung wildly as she pistoned back and forth, beads of sweat rolling down to the tips of her fat nipples. Suddenly, she threw back her head and released a long groan. “Here it comes baby, get ready!” she cried, grabbing her titties and crushing them to her chest as she hilted into me one last time. I glanced downward, now fully alert as I anticipated her orgasm.
When it arrived a moment later, it did not disappoint. There was a bursa escort huge pulse inside my gut as her cock swelled, and then a sound like a faucet being opened heralded the first gush of semen. My already bloated belly visibly expanded outward as the first jet of cum forced my skin to stretch in order to contain its volume. The second squirt continued this, and it wasn’t until the third blast of jizz that my stomach finally reached its limit. Having nowhere left to go, the remaining cum forced its way through the tight seal of my asshole against her shaft, and coated the area between us in thick layers of sticky cream. My own erection joined hers in unloading its contents, shooting upwards to make small splatters against the bottom swell of Sheila’s chubby belly. Once the last rope of semen had been unloaded from both of our testicles, her eyes slowly slid shut from exhaustion and she folded down to smother me once again with her lush and curvy body. My head found a space in between her massive cleavage and as I luxuriated in the feeling of her cock softening inside of my ass my own eyes closed and I fell peacefully asleep.
The Next Morning:
My eyes fluttered open to the dim light of the lamp on the bedside table and a number of strange sensations coming from different parts of my body. The first one I noticed was the powerful tingling sensation in my chest and thighs. Upon glancing down I noticed that my nipples were both very hard and visibly more puffy than they had ever looked before. Further down my thighs also seemed subtly different, pressing together in a way that suggested more thickness than my normally skinny figure possessed. “That’s odd” I thought to myself, but I quickly dismissed this issue and turned my attention to the poking sensation that was still present in my asshole even after a night of sleep. Clearly Sheila had adjusted positions at some point in the night but had reinserted her cock, only something didn’t feel quite right. I turned my head around to investigate and was immediately greeted by a shocking sight: instead of the thick black beauty I had been with last night, there was an entirely different woman currently penetrating my butt!
“Oh good, you’re finally awake! I really need this morning wood taken care of!” were the last words I heard before I was once again fucked by a futanari.
