Wife takes a bath, husband stays downstairs with old friend. Brings up friend's flirty advances on wife. Boldly offers: she's naked upstairs, face down, ready for anal pounding. Friend hesitates but seizes chance, with husband watching closely. He mounts her fresh, soft body, penetrates and stretches her ass inch by inch. Turns into hard, deep thrusting; her genuine moans echo. He blasts cum into her white butt. The intense scene realizes everyone's hidden cuckold anal desire. Explicit, depraved fulfillment.
