Ava and Natalie, bored with books, invite a third for some hands-on learning. Ava's round tits press against Natalie's as they French kiss, their hands exploring each other's bodies. Their guest joins in, his massive cock stretching their eager mouths. The teens trade places, Natalie's ass cheeks slapping against Ava's as she takes a pounding from behind. Ava's pussy clenches around a throbbing cock, her moans muffled by Natalie's thigh. The room fills with the wet sounds of pleasure, until all three collapse, panting and covered in sweat and cum, their "studying" complete.
