Tired from the day, Ardientes69's stepson sprawls out on the couch, his gaze wandering over to his stepmom's ample ass as she bends over cleaning. Unnoticed, he begins to stroke his hardening cock, his breath hitching as he pictures her thickness surrounding him. As his pleasure builds, he can't help but let out a soft groan, drawing her attention. She turns, feigning anger, but her eyes betray her, lingering on his tented shorts. Wordlessly, she approaches, straddling him and grinding her ass against his cock. He groans louder, his hands gripping her hips as he thrusts up, fucking her through their clothes. With a final, guttural moan, he cums, his hot seed coating her big ass.
