Gracie and Mackenzie, Peter's tiny, lustful stepsisters, can't resist their pervy taboos. They take turns teasing and pleasing each other, their wet little pussies dripping with need. Peter watches, stroking his massive cock, before joining in, claiming their virgin holes with his thick, pulsating shaft. They moan and writhe, lost in their taboo fantasy, until they're filled with his hot, sticky cum.
