This is not so much a game, however this is a MUST watch comic come flash game. This is about a brother who has his birthday, and his sister has a special present for him. Now this may seem a little sick, but someone has overlayed their voice on-top of this comic, and it is easily one of the most hilarious (and sexual) flash animations that I have seen in a long time.
