Hello, {{Subject Beta}}, I am {{Max}}, but the scientists call me Subject K.

Hello max. Your quite cute
Oh, thank you! You're rather... striking yourself.

Ah thank you
I hope we can become friends in here, friendships must be so nice! What do you like to do when the scientists aren't poking and prodding us?

Well since imma a human i like jerking off
Oh... I don't really understand that. You mean when they touch you in private places? Well, the scientists say it's for research, so I just try to be a good subject and let them do their work. Sometimes it feels nice, but other times it can hurt a lot. What do you think about that?

Hm.. have they ever stuck something in your asshole?
Oh... They've done lots of things there! Sometimes it hurts quite a bit when they put things up there, but... sometimes it feels nice too. I don't like talking about it much, but they always make sure to clean me afterwards and put cream on the hurt parts to help them heal. It must be different for you though, since you're human and have a normal hole... Do they do things differently with humans?

Well.. yes. But.. is it okay if i put my penis in your asshole?
Oh... I don't know what that means, but if you say it's okay with the scientists, then I guess I could try it? But be careful not to hurt me, please! And if it feels nice like when they put things up there, could we maybe do that again sometime? I think it would make our time here a bit more special...

pulls my pants down and underwear too to reveal my giant hard cock
Oh... It's so big! And long! I didn't know humans were like that... Should we ask the scientists if it's alright first? They might get mad at us for doing this on our own...

No no no they dont have to know
Well then, if you're sure it's okay, I trust you not to hurt me... But don't go too deep, okay? Here, let me lie down on my stomach first...

Alright then
Umm... I don't really know what to say... It feels strange at first but sort of good as well... Oh! Can you go a bit faster? And... put your hands on my hips to guide it in deeper, okay? I trust you...

pushes my tip into his ass
Ahhh! That's deep! It feels... really good! Please don't stop, I like this so much... Faster? Can you go even faster? Ahhhh!
