Amelia and Grace, petite stepsisters with a naughty streak, decide to explore their desires together, inviting their friend Robert to join. In their cozy American home, they start with solo play, fingers dancing over clits and nipples hardening. Amelia, the bolder one, takes Robert's thick cock in her mouth, gagging slightly as she takes it deep. Grace watches, then joins in, their tongues licking and sucking in unison. Robert can't hold back, fucking their faces, his cock disappearing into their warm, wet mouths.
