Under the pool's shimmering surface, a young, lithe beauty floats, her pert breasts breaking the water as her stepbrother, armed with a bottle of tanning oil, approaches. He massages her skin, his hands lingering on her curves. She arches into his touch, her breath hitching as he slips a hand between her legs. "I'll be late," she whispers, but her body betrays her, grinding against his fingers. He lifts her onto the pool's edge, spreading her legs wide. With a wicked grin, he dives in, his tongue exploring her folds. She whimpers, then pushes him away, taking his throbbing cock into her mouth. He groans, then flips her over, fucking her pussy from behind, their bodies slick with oil and desire.
