Rubbing on LetMeJizz
Two bodies grinding with clothes still half on is the usual starting point, a slow dry hump that builds long before anything comes out. Sometimes it is a cock sliding against her ass or thighs, sometimes fingers working a clit through soaked fabric. The friction itself is the event, the teasing stretched out instead of rushed toward penetration.
