see thats where you're wrong.
i've come to the realization that i was about to let one rip in a otherwise calm pool with other people in it before..... simply start swimming or say "i gotta go get something" and start swimming to the side of the pool.
splashes will cover up the fart. works like a charm.
in all seriousness though, either bj or reverse cowgirl
public places or events like funerals and weddings and what not aren't always that bad cause theres others to blame it on/you can act dumb. when it's just the two of you... theres no getting off the hook haha
