Fuck! Where am I and who's in my asshole?

I somehow have no idea how I got here but if I'm already in such an SM basement then I can let it rip right away, but I wonder who's in the back of my asshole, because my rosette feels mega filled! His thick cock pushed in and out again and again and fucked my round gorgeous ass to the extreme! I don't have a clue what's going on here but I think it's really cool! It totally turns me on to be anally penetrated by some stranger's cock until I come!
