Best friends since childhood, two curious teens sneak into their stepbrother's room during a sleepover, drawn by his late-night moans. They find him stroking his thick cock under the sheets, and curiosity turns to lust as they join him, stripping off their pajamas. The stepbrother's eyes widen at the sight of his sisters' tight, young bodies, their perky tits and smooth skin driving him wild. The friends take turns sucking his dick, their inexperience making them eager to learn. The stepbrother returns the favor, fingering their wet pussies until they're dripping. In a heated frenzy, they take turns riding his cock, their moans filling the room as they explore their newfound desires.
