Peeked through the half-open door and froze: your stepmom in that tight tank top bent over the couch, ass up for a younger guy with no shame. Thick thighs shaking as he grinds deep into her pussy from behind. Then she turns around—no panties left—and straddles him right there on the cushions. Tits bouncing while he lifts her by the waist, fucking her like she’s been waiting all day.
