You wake up confused and naked in small enclosed space with a hideous stench surrounding you. There is a giant cow centaur ass jutting out from the wall, mere feet away from your throbbing member. Seems like a dream for many, but that shithole is really nasty and packed with manure - and this is the only hole you will get, and only meal for you too - since people that trapped you there want to see you humilating yourself trying to breed that nasty ass. To make it even worse, it happens so that your prison is also a septic tank for that rancid rear.

To make it a bit better, that centaur is a pretty nice girl - you can chat in breaks of being tormented by her waste and farts blasting you and your small . Yeah you also have small in this scenario.
