Shy 18-year-olds Emma and Alex, cousins visiting for the summer, find themselves alone and horny. Emma, with her natural, perfect tits and hairy pussy, starts fingering herself in the bedroom, her moans echoing. Alex, hearing her, approaches and finds her in the act. Instead of leaving, he joins in, his thick cock stiffening. They tentatively stroke each other, Emma's small hand wrapping around his shaft, Alex gently rubbing her clit. They explore each other's bodies, coming together in missionary, Emma's legs wrapped around Alex's waist as they cum together, their first mutual masturbation session ending in sticky, satisfied smiles.
