Veteran “Fuck-Happy Teacher” Momoka Ogawa takes adult student role-play performer Runa Yamagishi through a pussy-to-mouth sex lesson. She demonstrates with a dildo, then brings in an assistant to alternate between sucking a real cock and riding it, mixing bodily fluids into a white, slippery foam. Momoka even demonstrates creampie P-to-M sex. Inspired and thoroughly aroused, Runa joins her for a threesome and tries the same routine herself, displaying an eagerness for cock unlike anything seen from her before.
