Macy Marx, the petite teen, misses the innocent cuddles with her sibling. But now, she's grown, her body ripe with desire. She tiptoes into his room, clad in a tiny nightie, her small tits pressing against the fabric. He's awake, his eyes roving over her curves. She climbs onto his bed, snuggling close. But this isn't the cuddles of old. Her hand finds his cock, hardening beneath his boxers. She strokes it, feeling it grow. He groans, his hands cupping her tiny tits, thumbs brushing her stiff nipples. She straddles him, grinding her pussy against his hard-on, her nightie riding up, revealing her bare, wet slit. They're no longer just siblings. They're horny, fuck-crazed teens, exploring their forbidden family fantasy.
