Yuta returns home for the first time in a while and learns that his childhood friend Suzu has gotten her first boyfriend. Although Yuta hasn't known them as the opposite sex since their school days, he feels a little complicated. Suzu approaches Yuta and asks him to be her blowjob practice partner. Yuta refuses at first, but says, ``There's no way I'm going to do it with a real thing!'' and Yuta lets Suzu practice giving a blowjob using a dildo. Suzu practices hard for her first boyfriend. However, out of jealousy, Yuta lies to Suzu and tells Suzu that his intense deep throating is normal.
