When you put your willy under a bbw's double chin and pork her until you jizzy jazz.
Chin sex:
Guy: Hey you fine fluffy thang, I find your chin chinsatiable, mind if my dong rides your neck all night long?

Sexy bbw: mmmmm yes daddy, do yo thang, I'll just be laying here eating bon bons and tweaking my nippular area.
