Legs secured in stirrups, ultrasound probe pressed against my lower stomach, a thin tube of endo camera in my pussy sitting positioned just right to give a perfect view of my cervix. And a half dozen researchers in the room standing by my legs, ready to take notes on every little thing that may happen. I heard them talking among themselves this morning. They waited months for this moment.
"We can begin. Release the specimen."
Something cold and wet glides between my sensitive folds - the speculum they used for the initial examination was removed for the experiment itself, but the sensation of being stretched quickly comes back when something slimy swirls around my hole and easily slips inside.
I don't see between my legs through the sheet that was put over them but the ultrasound image and the endo camera feed on the screen let me know exactly what is happening. This "specimen", a living, moving mass is making its way through my pussy, expanding and contracting on its way deeper. I gasp from the stretching sensation and the skin of my stomach mirrors its movements, bulging under the probe the researcher is pressing down on a little too hard.
"We have a visual."
A dark, rippling mass fills the screen, leaving the cervix visible just barely enough, but from the overwhelming pressure alone I know exactly what's going to happen. The tentacle changes shape into a pointed, needle-like tip and without any warning strikes the entrance of my uterus. I cry out and feel my eyes burn.
"Secretion of analgesic pre-seminal fluids. Hormonal and physical stimulation of the test subject began."
The excrutiating pain and pressure of having my cervix stretched quickly dissolves into feeling of pleasant warmth. The tentacle inside me starts moving again, slowly and rythmically filling my pussy and womb with whatever aphrodisiac it produces to make its victim all relaxed and docile. Mere seconds later my entire body is tingling in hot static and when more tendrils start lapping at my clit now covered in the creature's fluids, my legs cramp and I let out the most obscene moan I would be ashamed of in any other situation.
"Orgasm confirmed," the ultrasound tech presses down even harder in attempt to keep my pelvis in place, but the only thing I feel is my pussy and the entire lower half contracting in synch with the frantic ECG monitor I am hooked up to.
"Cervix dilation?"
"Sufficient. Egg deposition begins. Readjust the camera."
My vision is blurry and mind pleasantly unfocused from whatever hormones the creature pumped my system full of, but I'm aware enough to give the screen a passing look. The tentacle is semi-translucent now, buried and anchored long past my cervix, somewhere in my womb. And as the translucent tentacle starts filling with round, marble-like objects, I understand why the experiment called for the subject to be mid-cycle and not on any birth control. I breathe heavily as I watch the creature's eggs slip past my numb cervix, one by one.
All researchers' eyes are glued the screen as they watch the creature breed in real time. This is it, this is the moment they put endless hours of preparations into. A conception of something new, something out of this world. They needed to make sure it will work. And that every moment of it will be recorded and catalogued, so it can be repeated again.
I won't be leaving the research facility for quite some time.
