The protagonist, who was on weekends off, went to his best friend's house to hang out. His sister, "Unpai," was also home, so the three of them played games together online. The protagonist, still a virgin, couldn't help but stare at Unpai, who was wearing very revealing loungewear. They floated over, but the game quickly went awry, yet everyone still had a lot of fun!
It was late at night, and the guy's best friend had fallen asleep on the sofa. Unpai approached him and noticed he had an erection! She tentatively reached out and grabbed it! The guy didn't resist at all; after all, what virgin could resist a busty, beautiful older sister? Unpai took advantage of him, pulling down his pants and riding him hard! So this is what a woman's vagina feels like...?
The male protagonist, overly excited and suffering from premature ejaculation, was completely unable to satisfy the insatiable Unpai! So, during his vacation, Unpai relentlessly trained him to ejaculate inside her! She was determined to teach this virgin boy what the adult world was like, and to train him to be familiar with a woman's body so he would never ejaculate prematurely again… However, after three days of continuous training, the male protagonist did ejaculate again and again, accumulating 30 ejaculations inside her!
