Lured by the high prize money, they agreed to take on the swapping mission, exchanging boyfriends and moving one to the next room → game start with a single sliding door in between! ... At first, the four of them were shaken by the erotic mission written on the flip, but gradually their sexual desire rose and they kissed, licked, and sucked while trying to hold back their voices → and then they had sex! Both friends were fucked raw, and the excitement did not stop, leading to continuous creampies... With that momentum, they opened the door and started a four-way orgy! Repeating swapping, they entwined with each other, fucking and creampieing each other, creating a super erotic space filled with lust...
