Daisuke, a son, finds a dirty bodysuit in his mother Reina's closet. Reina appears and says, "Since you found it... you have no choice but to wear it," and the bodysuit contest begins! Even though he is fully clothed, the nipples, belly button, and pussy lines are clearly visible through the fabric... Daisuke swallows his saliva at the accentuated lines of his body, and Reina gets on all fours to show off the tight costume that clings to his plump body!
