Two innocent teens, virgin but curious, find themselves in a taboo threesome with a well-endowed lover. As they explore each other's bodies, the teens tentatively touch, lick, and stroke their new partner's thick, throbbing cock. The experienced lover guides them, teaching them to take it deep, one in her mouth, the other riding him reverse cowgirl. The teens moan, their tight pussies spasming as they're filled and stretched for the first time.
