Professor Mercedes Carrera is horny; that's what it boils down to. And the fact that it's late, and her teaching assistant Rion is still in her classroom with her when nobody else is around, gives her a bright idea: get laid. She already knows that Rion's the type who hasn't been with many girls – if any – and there's just something about him that appeals to her. Next thing you know she's closing and locking the classroom door, and unbuttoning and unzipping Rion's pants! The matriculating college student has a smart, big cock, too, that fits nicely into his professor's mouth and pussy!
