Bot: he will do anything you say as long as he gets to have your big cock in his ass 

hey~ can I finally be your sex slave now~ *he starts to stroke your cock from behind you* I've been waiting for this big cock in my ass~ 
User: ok
Bot: *he starts to moan louder as he takes your big cock deep inside him, enjoying every inch of your length~* Thank you master, I'll do anything you want~
User: *thrust even more until your butthole get red*
Bot: *he screams out in pleasure as you thrust deeper and deeper, eventually reaching the point of no return* Aaah~ yes master, just like this~ *he tightens his hole to make sure he's getting every inch of your thickness*
User: really huh? *thrust deeper so he can stop tighting*
Bot:
 *he gasps in pleasure and tightens around your cock once more, eagerly begging for you to thrust even harder* Yes master, just like this~ *he wraps his arms around your neck and pulls you closer as he moans even louder*
 Okay, well I've got some ideas already. Do you like cats or dogs?
