lil excerpt of Genji with horse (centaur) Zenyatta:

It isn’t easy to suck Zenyatta off; his cock is too fat to stuff into his mouth and let him throat fuck him, but Genji nonetheless is always eager to try. He drools liberally, getting everything wet and slick as he sucks at the tip and moves away with wet, messy pops as Zenyatta tries to stand still but ultimately has to dance around a bit, his small hoofs coming close to hitting Genji every now and then but never touching him.
