FP and the alternatives question

[Missynissy]

So aside from fourplay, I'm largely curious as to what kind of sex mods can be used. I've done a bit of looking and haven't really seem to find anything close to Fourplay but i'm also wondering if there is no alternative to fourplay how you get the animations to line up properly, as they had never been aligned properly for me. I'd also be interested in hearing what kind of adult mods every one here uses

Fourplay is really obsolete. Use AAF instead.
