Although he managed to enter the enemy’s secret base as a spy, he was accidentally arrested during an operation. After being tortured and forced to confess, the male spy was taken into a pitch-black room where he screamed loudly into the darkness.
“You have no more valuable information to offer, and now you are nothing more than experimental material for us.”
I don’t know what part of the room the voices were talking from.
“Experimental materials?”
“Yes, that’s not what you infiltrated our base for. Now let’s make you the test bed for our secret weapon.”
A door in the corner of the room was opened at the same time as the voice speaking with a sarcastic tone died away.
“Puff, puff, puff,” accompanied by a sound that seemed to be something oily dragging on the ground, the guy was getting closer to me.
“Let me introduce you. The one that’s coming toward you right now is what we call Experimental Lifeform 8.”
It could be vaguely seen in the darkness, as if it were a giant octopus-like creature with many tentacles.
“The original form of that thing was a creature with interesting reproductive abilities. Originally it was hermaphroditic and could form fertilized eggs on its own. But because it doesn’t possess the organs to nurture a fertilized egg, they have to put their fertilized egg into the womb of another creature and grow inside that creature. Even more interestingly, if the creature at its disposal does not possess a uterus for the occasion, it will remodel that creature’s body, forcing a uterus to form inside that creature’s body.
“There’s no way such a creature exists in this world.” I countered.
“It exists, what you have in front of you. And we have even modified the creature so that it can be used on people. But it’s well just a theory, no experiments have been done. You’re in luck.”
“Hard, is it ……”
Indeed when this mission was accepted it was mentioned that the enemy was now working on biological weapons. Thinking about this, the male spy was horrified at what was about to happen.
“It looks like you understand what’s going to happen. Then please enjoy yourself.”
As soon as the words left his mouth, the tentacles wrapped around the male spy’s body.
“Woo.”
The tentacles were larger than the man’s body and very sensitive. In an instant, the man was wrapped in the tentacles. He struggled strongly, but the tentacles were very strong and full of elasticity. The man couldn’t even move. The tentacles flipped all over the man’s body. At the same time, from the tip of the tentacle, a mucous membrane-like object was continuously secreted, and it could be felt that the mucous membrane was penetrating all over the body.
“Oooh, ah.”
The muscles touched by the mucous membrane began to spasm intensely.
“Start with the physical changes.”
The tentacles that wrapped around the whole body gradually concentrated towards the femur, and finally gathered on the penis and began to move irregularly. The sensation of the penis being wrapped around the smooth tentacles was a sensation that had never been felt until now. Normally, one should have felt pleasure by now. But the man’s penis had the opposite reaction to that──it gradually shrunk!
“No, it can’t be ……”
“It seems like it’s surprised. A man’s genitals are useless to it. So like this, the male genitals are removed to make it a female organ.”
As soon as the words left his mouth, the man’s penis had completely disappeared. At the same time, the chest hair on his chest. The leg hairs on his feet had also fallen off. Then the tentacles began to wrap around his chest. Then the tips of the tentacles began to ooze out transparent liquid, and before long, the man’s chest was coated in liquid.
“In, in.”
The man felt the clear liquid seep into his chest. Not only did he feel it, but from the looks of it, the man’s chest gradually swelled out, and in the end, his chest had risen to a size that could not be covered by two palms. The tentacles once again swam towards the man’s femur once more.
“No. Don’t come in.”
There was no longer a penis between the strands, and the tentacle kept pushing its way into the man’s interior. It could be felt expanding inside as it entered wetly.
“Ah.”
Just like the chest just now, it could be felt that the tips of the tentacles were secreting mucus. Those mucus gathered inside the body and finally seemed to form something.
“It seems that the transformation of the body is complete.”
Now, this body that used to be a man could no longer see any male features. Any way you look at it, it looks like the body of a woman in her 20s.
“Then since the body has become a woman, it should now be able to assist it in accomplishing reproduction.”
“No kidding.”
The male spy who was now a woman fought back desperately. Trying to break free of the tentacles.
“Hmph, it’s true that just like other creatures, humans can’t accept the fact of becoming female.”
“Nonsense, rightfully so.”
“The implantation of the fertilized egg might not go well with a fidget like you’re doing oh. But they originally knew that this would happen, and they naturally have a way to cope with it. You don’t have to waste your efforts.”
Just as he was about to say something, the mouth of the male spy who had turned into a woman was gagged by a tentacle.
“Woo, woo.”
Liquid was forced into his mouth. Immediately, I felt heat begin to rise in my body.
“It’s one of the winks. After you drink it, you won’t think about anything other than reproduction.”
It’s like he said. My body was getting hotter and hotter and I couldn’t think of anything else but making love. That’s the feeling I experienced when I was still in a man’s body, but my body reacts completely differently now than it did then. The penis that used to get bigger when my sex drive was high was gone. Instead, there was a heat deep inside my body, as if I wanted something. It wasn’t just between the femurs, the breasts wrapped in the tentacles were also constantly burning and rising, and their size was already much larger than it had been just a moment ago. The nipple at the front of it, as if it was being pulled by transparent strings, was rising and hardening.
“I want it, I want it ……”
The woman spread her legs herself and pushed her waist forward.
“Aha.”
The tentacles had re-approached the femur. With the sound of “Puff, Puff”, the tentacle was pumping back and forth between the woman’s femurs.
“Good, so cozy.”
This experience was the first of its kind. It was the first time that I felt pleasure from having something inserted into my body. Unlike a man’s penis, the tentacle was able to change its shape freely, and it clung to the female genitals. The opening of the uterus, the walls of the vagina, and the clitoris, both large and small, were intensely stimulated.
“Ha. Ha. ……”
Not only the shape, but its movement was something that a human penis could not simulate. It flipped inside me, expanding and shrinking one moment, and all the nerves inside the genitals were stimulated by it in various ways. Gradually something not unlike the slime of the tentacle flowed out of the woman’s vaginal opening. The movement of that voracious tentacle was not limited to the vaginal opening.
“Ah, there’s …….”
A tentacle made its way to my chrysalis court, the slime-covered tentacle ignoring the resistance of my anus and going in whole hog. The tentacle tumbled inside me as it stimulated the sensitive entrance. It stimulated my genitals from different angles through the thin walls of flesh inside my anus.
“More, I want more ……”
As if in answer, several tentacles reached for the woman’s breasts. Originally, I thought it would wrap around the rising breasts, but who knew that the tips of the thin tentacles were inserted into the nipples. The breasts, which were already C-cups, had risen two full circles. And it wasn’t just that.
“Ah, so cozy.”
The chest area was again covered with mucus, and the breasts absorbed this mucus and changed further.
“Z.”
Breast milk overflowed from my breasts at the same time the tentacle was pulled out of the nipple. For a tentacle that treats its partner as a reproductive prop, doing this kind of thing is all instinctive.
Breasts, vagina, anus, all parts of my body were being stimulated as I gradually approached the overwhelming peak of a woman’s faculties. If it was a man, it would be fine to cum several times, but now I could only passively accept the tentacle’s alms. My moans gradually rose to a high pitch, and the tentacle’s movements between my strands slowed down. But the ones inside me were moving more intensely. My entire body, covered in erogenous zones, suffered unprecedented stimulation. The tentacles in my mouth tightened around my tongue. The tentacles around my breasts were firmly wrapped around my breasts. The tentacles on my nipples were attracting my milk with full force. The tentacles inside the anus were doing intense pistoning movements. The tentacles inside the vagina were constantly expanding. Finally the tip of the tentacle that entered the uterus ejected a large amount of fertilized eggs.
” ah …… ！！！！！！”
The woman finally reaches the top and passes out.
