New MM-ban project! A friendly couple on a double date that was called out to in the city takes on the challenge of "Boyfriend Swap! Open-Air Stripping Tsu○ster"! They cooperate with their friends to clear the missions, but the missions gradually escalate, and they are on the verge of exploding in front of their best friend's girlfriend's divine I-cup breasts and fair, big ass! Furthermore, in a close-contact pose covered in slippery lotion that makes an erection inevitable, a slippery insertion into the JD's pussy happens! ? The sense of immorality makes them more sensitive, and they cheat on each other by having sex while looking at their beloved lover in front of them! Swapping creampie!
