[Umino Sachi] Gakkou...

A buxom, bespectacled principal finds herself cornered by a scheming schoolgirl named Kazuki and her eager friend, who moan about wanting her cock-feeling pussy stuffed thicker while pushing a marital affair into a steamy threesome. The nervous motherly figure with a heavy, hairy body and trembling huge breasts ultimately surrenders, letting the girls pry her puss open and fill every hole until she's a drenched, desperate mess begging to be finished.
