When I woke up I was still lying in the giant puddle of cum that the tentacle monster had left. My naked body was covered in it too. The semen on both the floor and my body had dried. The crusty white stuff was all over me and it flaked off when I rubbed it. Looking back at the insane intercourse I'd had with the tentacles left me feeling sick.
I groaned as I sat up. Sleeping on the hard floor had played havoc on my back. As I looked down I noticed a change that made my eyes widen. My breasts had grown. They were no longer DD cups as they had been before, I was now sporting F cups at least.
I placed my hands under my breasts and lifted them, marveling at their new weight. What the hell had they done to me? My new, massive breasts were sore, particularly the nipples, and when I touched them a dribble of white fluid leaked out.
"Fuck," I said. I'd been pregnant for a few days and my breasts had already grown and were lactating. I looked down at my belly and was relieved to see that it was still flat. Or as flat as it had been before anyway. No bump yet. The rest of my body looked perfectly normal, it was just my tits that had changed.
I looked up when I heard footsteps and I saw two black-clad guards coming my way. As they neared their brows furrowed at the sight of the mess I was in.
"The tentacor liked you," one of them said. I assumed he was talking about the tentacle monster. I refused to admit out loud that I'd liked the tentacor too. At the time I had, now, not so much. I looked away from them in shame and tried to cover my naked body. My breasts were simply too large to conceal properly.
"We'll take you to get cleaned up," the other guard said.
"Please don't restrain me again," I said. I couldn't bear to be carried around with my wrists and ankles bound like last time. My situation was demeaning enough as it was.
"We won't have to if you wear this." One of them pulled out a thin metal collar that looked like something you'd make a dog wear. Then I remembered that I was no more than a dog to them. I was just an animal to experiment on.
I sighed and nodded my agreement. They entered the cage and fitted the cold metal collar around my neck. It fit quite snugly, not too tight, but not loose either. I felt like I was their pet.
They led me out of my cage, allowing me to walk in between them this time. As we moved through the ship my enormous boobs wobbled and their new weight felt unusual. If I hadn't been pregnant I might have enjoyed the increase in size, as it was I was more concerned with what other changes awaited me.
We arrived in some sort of wet room. The walls were covered with plain white tiles and the floor sported puddles and drains. Oddly, there were no showers in sight. As I stepped into the room and the door closed behind me I saw a huge hosepipe attached to one wall.
"What is this?" I asked, looking at my guards.
"This is where we clean the animals," one of them said.
"Oh, hell no. If you think--" my collar sent out a zap of electricity that stiffened my entire body and sent a bolt of pain lancing through me. "Ow!" I shouted when it stopped and I regained control of my body.
"You will follow our instructions and will not argue or you will be shocked," the smaller of the guards said. He had a slight smirk on his little blue face. It infuriated me that these tiny creatures had such control over me. "Now, stand in the center of the room."
Not wanting to be shocked again, I stepped into the middle of the room. The shorter alien nodded in approval before picking up the hosepipe. A heavy torrent of water hit me, drenching me at once. I stood in its path, using my hands to spread the water over my body and scrub off the dried cum. I thought this might actually be the most humiliating thing that had happened to me so far. Being hosed down like cattle. They hadn't even given me any soap.
Once it was done I felt much cleaner. I was given no towel and was forced to stand in the room until my body was dry. The two guards stared at me the entire time, their dark eyes wandering over my body, hovering over my breasts and vagina. I shifted awkwardly and used my hands to cover as much of myself as possible.
Once dried, I was taken to another lab. It looked almost identical to Keldon's lab only it wasn't as nice looking. A small blue alien stood at a computer wearing the grey uniform I'd grown accustomed to.
"Presenting Subject H69, formerly known as Subject 004 in the Earthling trials," the taller of my guards said.
Great, so now that I was in the animal research department I was given a whole new name. This name was even worse than Subject 004. At least being number 4 seemed more important than H69.
"Excellent," the research alien said as he looked over at me. "My name is Uthel. I am the lead researcher on the Animal Research Team." He seemed friendlier than Keldon and without the creepiness of Grabanimo. "Please have a seat on the table."
I climbed up onto the metal examination table feeling self-conscious about my nakedness. "What's going to happen to me?" I asked.
"You will be experimented on so that we can determine how compatible your species is with other lifeforms. We have been in your galaxy for some years now and the humans of Earth are the first species we've found that can breed with other species," Uthel explained. So, I was going to be forced to fuck other animals. Great.
"What happened to the first 3 subjects before me?" I asked, already dreading the answer.
"Subjects 1 and 2 were male so completely incompatible with my own species. They were passed to me and have as of yet failed to impregnate any of the female animals in the menagerie."
So they were still here somewhere. They were probably in the same giant room I was kept in. Judging by my own subject name there were at least 69 "animals" in the menagerie. "What about number 3?"
"She perished attempting to escape. She woke up during the initial examination and tried to run away. Unfortunately, she was still connected to some of the laboratory equipment and it...split her open beyond repair," he said.
My face went pale as I realized how lucky I'd been to survive for so long. Even after some of my dumbassed escape attempts.
"So, now I am going to be fucked by every creature on this ship?" I asked.
