Blonde stepmom with perky tits strains against white blouse. Fingers wrap tight around stepsons rigid cock, pumping base to tip. Skin slaps softly at first, building rhythm. She leans in, mouth opens, sucks head with loud popping suction. Throat bulges as she takes more, gagging wetly, saliva dripping down shaft. Couch cushions shift under her knees. Heavy breaths mix with throaty moans. Blouse rides up, exposing soft curves bouncing lightly. She grips thighs for leverage, bobs faster, cheeks hollowing with vacuum pull. Precum beads, she licks it clean with swirling tongue. Stepson groans low, hips bucking into her face. Spit strings stretch from lips to cockhead. Tits heave with every deep bob. Room fills with slick glucking sounds, her eager hums vibrating the length.
