Peeked through the door just in time to see her stepmom’s ass flexing on the couch, yellow bikini strings barely holding on. Cock buried so far back she’s grinding against his hips like she owns him. Switches mid-thrust, straddles him raw—tits bouncing—and slams down harder than before. No lube needed for those heavy folds; sounds wetter every time he pulls out and slaps back in. Her legs start shaking when he pins them open wide, fingers digging into her inner thighs as if daring him to cum inside her again. The last shot? Both of them collapsed together, panting—her still wearing nothing but those soaked yellow strings.
