Heavy tits spill from her top as she leans in close, wrapping both hands around the stepson cock in the dim bathroom light, stroking firm and fast while her lips hover near the tip. Fingers dig into his shaft with steady pulls, building him up until precum glistens on her knuckles, her built curves pressed against the sink edge for leverage. She shifts lower, letting those full breasts brush his thighs as the pace quickens, veins bulging under her grip while he tenses hard. Kneeling now with knees on tile, she milks every drop onto her chest, cum dripping down her cleavage in thick ropes as she squeezes the base one last time.
