Its when a gay space cowboy inserts his dick into another man(or female with strap on into female). Preferably the buttsex is done in space or a space setting ( rockets painted on walls with semen). Lasers are involved as well shooting every as cum squirts in your anal.
When two big burly black men get in a fighting ring together and end up having sex and licking each others cum out of their assholes and then they pick the biggest one out of the crowd and gangrape them
