In the dimly lit living room, the amateur wife tentatively explores her friend's body, tracing his muscles and feeling his growing erection. He returns the favor, cupping her breasts and teasing her nipples through her thin shirt. She moans softly, her pussy growing wetter by the second. He pulls out his cock, thick and veiny, and she eagerly takes it in her mouth, sucking and licking until he's rock hard. Then, she straddles him, impaling herself on his cock, her pussy stretching to accommodate his size as she bounces up and down, fucking him hard and fast.
