Luna and her friend, clad in lacy lingerie, start their afternoon of confessions and caresses. But their intimacy is disrupted when Luna's boyfriend, hidden behind a book, reveals himself. Dropping his pants, he joins them, his hard cock sliding between Luna's friend's legs, making her gasp. Luna watches, jealous, then hungry, as her boyfriend kisses her friend deeply, his hands squeezing Luna's breasts from behind. The room echoes with their moans as they transition into a frenzied, unplanned threesome, bodies glistening with sweat and desire.
