It ends

You lost the sense of time. Sometimes you feel so aroused that you wants to cum but you can't. Sometimes you feel your ass, dick, balls, throat hurt but you can do nothing with it.

Without any notice you feel that your urethra is rhythmically stretched from inside. Soon after it you see some bulges moving inside the tentacle that is inserted to your mouth. These bulges move closer and closer to you and start moving inside. You feel that they stretch your throat, making you a bit uncomfortable.

You also see the larger bulges in the ropes that fuck your ass. These bulges stretch your ass a lot, hurting a bit.

Now you finally realize that all tentacles are pumping you! You feel your bowels filled with something. You feel strange and suddenly the bright green mucus flows out of your mouth. With a corner of eye you see that the same is happening with your ass - there is a lot of mucus under you. You wonder that you don't feel it - it seems that your ass has lost its sensitivity.

A minute later you feel the movement in your bowels and see the tentacles are moving out. The tentacles that holding your body also loosened and you slowly do down on your knees and hands. Finally, they move out of all your holes and release you. Green mucus leaked from your mouth. You finally can taste it. Surprisingly, it's not disgusting, it taste even better than sperm (you were very curious of it and tasted your own sperm. About a twenty times.). For a moment you feel urge to puke but then you fall down in green mucus and fall to sleep.

...

You wake up in your room in Facility. There are several cables connected to you but nurse quickly removes them.

"Good morning, Mr. Doe! How do you feel?" asks she with gentle voice.

"Oh, not bad as I would expected." answer you. You try to sit on the bed and you realize that you are naked. "Could you please give me a clothes?"

"There is no need of clothes right now. You will be observed by doctors now."

Really, the door is opened and a half-dozen of people enter room, two men and four women.

"Good morning, John!" says Dr. Banson.

The other doctors move the bed-sheet from you and you see your penis. There is a tube going from it.

Melinda quickly disconnect it. "You don't need it anymore." The doctors start touching your belly, your penis, your balls. You feel a bit uncomfortable to be treated like this with the presence of nice women.

"Stage 2, yes...mating... developing ... evolution... diet..." the doctors are completely ignoring your feelings. They say you to turn over. You do so and they start touching your ass.

After this examination they gave you a robe and take to the conference room. You feel that your ass and cock is hurting a bit. You see the diagrams on the screens, you even notice picture with your own face with thick rope in your mouth.

"The first mating was successful, Mr. Doe" says Sarah. "We should wait for complete evolving for one week. You have time to decide whether you want be **** during spawning or not."

"What? Do you mean that this thing is inside me?" ask you.

"Thing? There are dozen eggs in you. One in your bladder, three in your stomach and eight in your guts!" answer Sarah, happily smiling.

"Oh, fuck! Sorry ladies, I don't mean it."

"It's OK, it's normal reaction for our subjects. We will observe you carefully to avoid any complications. Do you have any special needs?"
