The girls' eyes widen as they take in the size of the man's throbbing cock, their previous fumblings with boys forgotten. He teaches them to worship it, to take it deep into their throats, to feel it stretch their tight pussies. They moan, their bodies betraying them, as they ride him, their hips moving in instinctual rhythm. The man's grunts of pleasure spur them on, their inhibitions falling away like petals from a wilting flower. The room echoes with their cries of ecstasy as they experience their first orgasms, their bodies convulsing with pleasure.
