That's odd.
The day had started just like any other day, but as I was walking to class, I heard a dull sound followed by a loud squeal just to the right of me. Having taught at the university for several years, I knew better than to pay attention to any unexpected noises on campus. However, this sound was different. It sounded like a dull, muffled pop that was loud in volume yet muted in tone. It certainly didn't sound like anything I had heard before, on campus or otherwise. In fact, it didn't sound like anything should sound like on Earth. I should know -- physics is my specialty.
The next odd thing I noticed was a neatly typed term paper flapping on the ground about in the light breeze. It was doubly strange because of the name on it... Venus is one of my best students. She is tall, tanned and slender... a real beauty with an hourglass figure to match. I have no doubt a huge number of guys have been chasing her shapely tail but she always seemed to be focused on her studies and not very interested in socializing.
She is always careful with her assignments, so finding one page of her paper flapping about was disconcerting, to say the least. My eyes turned to the direction from which it came, and I saw more papers flying towards me.
My curiosity piqued, I stepped off the brick path and waded into the bushes, following the trail of paper. What stopped me in my tracks was a bundle of clothes on the grass. They were clearly a woman's clothes, lying in such as way as to leave no doubt that their owner was now naked from the waist down. The waistband of the short skirt lay in a circle, within which I could see the gusset of the sheer white panties.
Now, I'm no pervert but the way I found the clothes set me thinking: it looked to me like she had stepped out of her underwear and skirt very suddenly... I could even make out the indentation her labia made on the gusset (it looked like she had really plump lower lips around a deep genital cleft). As I looked, the white cotton panties sagged onto the grass beneath, the beguiling shape disappearing before my very eyes. I hesitated, wondering if I should pick them up for a closer look, but was distracted by a sound further in the bushes. It sounded like a woman, squeaking while branches snapped and leaves rustled.
Cautiously, I made my way deeper into the brush. I was rewarded with the strangest sight I had seen in my life. Up to that point, at least. There was Venus, suspended in mid-air, her long hair and blouse in disarray. Of her lower half, I can only say I had a very odd view of it, since she seemed to be embedded in shimmering wall of some sort and her ass was facing me in a huge mirror image that was just behind her.
I should say that it was her naked ass I was gazing at, and in spite of the strange scene, I have to admit I began to get aroused. Her ass was white and round, the deep cleft of her hairless pussy peeking out from underneath the luscious globes. The mirror image was so large it felt as if I was just a couple of feet away from her quivering flesh. It hung in mid-air, a strange and sexy ass without the top half of an obviously curvaceous body. "Prof... I... what's happening?" she looked at me for answers. For once, I had no scientific answer to give her. I had heard rumours of such dimensional shifts occurring at random locations before, but they had always remained unproven fancies of weak and susceptible minds to me. Until now, that is.
Apparently, such shifts had happened with greater frequency in recent weeks, and a colleague even mentioned to me just the other day the theory that the Bermuda Triangle had shifted and a number of people had disappeared and remained unaccounted for because of such shifts. I made short work of his theory, of course... parapsychology is not even worth thinking about.
Now, it appeared I was confronted with proof of such dimensional shifts. My lovely student was stuck in one, and by some fortune (good or bad, it was difficult to tell), she was the first person to have been caught between the dimensions. I opened my mouth and closed it again, unsure of what to say to her.
I shut up also because I noticed that something was happening to her butt. Because it was an image enlarged and reflected from a perspective directly behind her rear end, I had to say I had a front row seat to the drama that was to follow.
Something was parting the globes of her ass. It was doing it slowly, almost like a lover would have done, and exposing the tiny pink ring of her anus. I have no doubt she could feel what was going on at her ass from the look on her face.
"Oh! I... uh... can you... umm..." she stuttered as her backside was lovingly spread by an entity I could not see. This was most unlike the confident Venus I was familiar with. Venus was a girl who didn't hesitate, either in answering or asking a question. "Please... umm... OH!"
I had the guilty pleasure of seeing her mouth mirror the 'O' formed by her anus as it was pried open by a cylindrical object. It was possibly conical in shape because her asshole appeared to be yawning wider with each second that passed.
"What's happening?" I asked, trying to hide my own arousal from the distressed girl while pretending that I was not a witness to her sodomy. "I... uh... nothing. It... feels... cold back there," she lied, perhaps too embarrassed to tell me the truth, that her ass was being deeply probed by some unknown entity. I watched as her back orifice stretched even wider, so much so I could look directly into it and see the pink walls of her rectum rippling in tandem with the motion of the invisible intruder. I wondered if she was telling the truth, that the thing penetrating her was cold.
"Can... you... umm... help... me?" she urged through gritted teeth. The experience of being fucked in the ass was probably a new one for her, and she was doing her best to maintain a calm tone. Venus was certainly a cool customer, not given to panic in the most difficult situations in class. Apparently, she was able to retain her composure even while she was being forcibly sodomized by something she could only feel.
"Sure, here, let me pull you out..." I grabbed her lower arms and pulled. Her flesh was smooth and soft... and suddenly goose-pimpled.
"Ooooh!" she exclaimed, and I could immediately see why. Something was pushing at her pussy, flattening her lips while spreading them apart and revealing the moist pink flesh in between. It looked like something was... licking at her privates, because of the movement of her labia -- it was pulsing, the fat lips opening and closing with alarming regularity. Her privates began gleaming with the juices flowing from deep inside, and I could see one droplet glistening on the end of her now erect clitoris. From the flush on her face and her panting, I knew she could feel it too.
Venus gamely tried to look calm even though I could feel her pulse racing. Good girl! The last thing I needed was hysterics. I tried harder to pull her out and away from whatever it was that was attacking her, and was successful only for a few moments. Whatever it was that was holding her in place seemed to react to the force of my pulling and the shimmering wall suddenly surged towards me before retreating. I was jerked forward by the sheer force of its reaction, noting that her blouse and bra had dropped to the floor between us in the meantime, leaving just her head and bare shoulders sticking out of that damned wall. She knew that I'd seen her bra and blouse drop and blushed a deeper red.
I pretended not to notice. "I'm sorry, I don't seem to be helping," I said. "Maybe I should go and get somebody..."
"No! Please don't leave Prof..." I could see her eyes getting wet. Poor Venus was getting scared even as she was being incredibly aroused. The droplet had fallen from her twitching clit, only to be replaced by a much larger one. I watched it tremble and drip as she shivered, perhaps in fear, or perhaps in excitement. The flow of lubricant from her reddening slit seemed to be increasing. Just beyond that, I saw her naked breasts heaving as she gasped and panted.
"But it doesn't look like I can do anything!" I protested, releasing my hold on her arms. She responded by grabbing me, her fingers digging deep into my upper arms. She was shuddering by now, perhaps in anticipation of what she knew would happen next.
I admit I was fascinated by the sight before me: her asshole opening ever wider while the gentle lapping at her vulva ceased, quickly replaced by something that seemed to be probing into her genital cleft.
"Oh! Oh! I... It's... It's going..." she gasped as the probe moved ever closer to her helpless vagina. "It's going innnnn!" she squealed as I watched her orifice open like a blooming flower. It didn't look like anything she couldn't handle, at least not at the beginning, but given the way her asshole was being stretched so, I wasn't sure the same thing wouldn't happen to her pussy too. A tear leaked from the corner of her right eye.
That was the moment when I made the decision. Whether it was a good or poor decision is still open to debate, I suppose, but I rationalized it thus: since pulling wasn't helping, perhaps pushing would. I had no idea how it would turn out, and reasoned that the dimensional shift could either push her out in response to the force I was exerting (which would mean I would have a very naked Venus in my hands afterwards), or it could swallow us both. Either way, I had to try... Poor Venus was clearly in distress at being double penetrated by some unknown entity behind her.
Her eyes widened and she screamed as I pushed her back onto the thing probing her ass and pussy. I had one last exciting look at her plump vulva bulging, the lips opening even wider as more of the thing pushed into her. Then everything seemed to shift in a kaleidoscope of colour which quickly swirled into a deep dark pink drainhole.
I found myself holding on to a very naked Venus in a cavern of some sort while some strange plant-like organism plundered her ass. The mirror had disappeared, so all I could see were her heaving breasts, her pink nipples hard and moving in quick tandem to her breathing. Of her ravished ass, I could only see the thick greenish vine reaching up from the ground to somewhere between her ass cheeks.
Apparently, there is a slight time lag between the dimensions, because one of the first things I noticed after I realized I was similarly naked was that there was a rather large knob-like extension reaching out for her pussy. Perhaps the earlier sensation of being raped by the huge knob was still on her mind as she gasped and stood still, unaware that in this alternate reality, she was yet to be penetrated. The thing was getting very close to her snug cleft.
"Hey! Venus! Snap out of it!" I yelled at her and pulled her towards me, and away from the thing aimed at her pussy. Thankfully, the creature aiming to plant itself into her did not seem to offer much resistance.
The matter of its 'anchor' in her ass (we worked out its purpose later) was another matter. That I was able to pull her away so easily also meant that it was highly likely that it would break off while it was still inside her, and there was no way I could tell what the effect of leaving that alien object deep in her ass would be.
Poor Venus was still a little out of it, so I took the course of action I thought was best. I pushed her onto her hands and knees, spread her lovely ass with my hands and began to slowly pull the object out with my right hand while my left held her cheeks apart. The funky smell of her asshole filled my nostrils as I drew it out, marveling at the size of it. I couldn't believe that the tiny bud of her anus had managed to stretch to swallow such a huge object into her butt. It was not streaked with brown, and in fact looked spotted with pores, which I suspected was used to absorb whatever it could from her body. It wasn't too particular about absorbing shit, apparently.
