Sims 2 Wank!
At a lovely Sims 2 site I like to frequent (http://www.modthesims2.com), they have variously things such as some of the first hacked Sims 2 objects, and tons of really neat mods (Twins every time, Abduction every time, etc.)

In the forums, on the Beta Testers board, jtravers88 posts that they have created a Mod that will let Teens WooHoo (Sim name for sex) with other teens, as well as adults and elders. Only problem is that they can't figure out part of the coding and the mod allows children to WooHoo as well. Nevermind that adults and children would be kissing thin air, thanks to height differences (adults tend to make out with teens on their foreheads, teehee), it starts a rather nice little wank about child molestation, lack of morals and how Temporary is the only one with religion on the board.
