sex organs throb on orgasm
in old versions of the game the vagina and balls would "pulse" or "throb" during an orgasm. This no longer seems to be in the game and would be a nice little detail to come back during the games polishing stage.

i definitely agree on the genital throbbing, that's hot. Especially if he makes it so that the more they've been built up and the harder the orgasm is, the harder their genitals throb and jump.
Pussies puffing up and reddening with arousal could be a nice touch too
