His father, unable to see Toru in his second wave, asks his friend's wife, Yui, to be his tutor. However, Toru is distracted by Yui, a beautiful woman with glasses, and cannot concentrate on her studies. Yui, who can't stand her, makes her touch her breasts with the promise of studying with her, but Toru's gestures gradually escalate and she ends up being cummed. In addition, Toru sticks out his cock, which has turned into a gingin, in front of Yui.
