Bumming 

Gay sex

Matt sucked and wanked lee's big cock. Then Lee sucked Matt's dick , fingered and licked him until Lee put a condom on and got ready to fuck him.
"Ah, oh yeah " shouted Matt as he was getting bummed up the arse by Lee. Lee's balls smacked against Matt's arse. " Harder,Harder " Matt screamed as he wanked his dick.
Lee whipped off his used condom and wanked his cock until he shot his cum all over Matt's body. Then Matt shot his juicy load over Lee.
They laid on the floor covered in cum. They both love bumming now.

Ooh! What happens? Do you alway bum him or do you bum each other. I don't know much about bumming, sorry I mean qu.., sorry, er, gay people and stuff. Well you know, we girls always say gay men are wasted. Is that offensive? Could I really suck your cock and you wouldn't get a hard on

wall bumming 

Standing in a corridor (at school/work etc) with your back against a wall and using your bum to push yourself away from the wall, and using it to cushion your return to the wall. Can be used to pass the time while waiting for a class to begin/person to arrive. Is closely related to bum walling.
