(Haa... How can I rub my mother's breasts?) Yusuke was troubled by his mother Mikuru's big breasts. Even though he's just doing housework, the boing boing shaking breasts in front of him can't stop his libido. (I really want to rub it!) Yuusuke gives up trying to put up with it and comes up with a strategy. Yuusuke tricks Mikuru into closing his eyes by deceiving him as a surprise gift and restrains Mikuru.
