Rin is dating Wataru, a speed skater. Daikoku, who lives in the opposite room, can see everything in Rin's room through the window. Because she didn't think she would be peeked at, Rin often changed her clothes, and even had sex with her boyfriend right by the window! Each time, Daikoku peeked at Rin and masturbated. Until one day, Daikoku deliberately waited for Rin to go to the garbage to get the condom containing the sperm that she was going to throw away. While talking, Daikoku inadvertently reveals that she is peeping on Rin, causing her to run away in fear. Knowing that he couldn't hide it anymore, Daikoku immediately turned his card upside down. He used sex photos of Rin and her boyfriend to intimidate her. Daikoku first asks Rin to look at her nipples, then gives him a lick, and then forces her to suck his cock! Daikoku's request is getting more and more outrageous, but Rin has no choice but to obey him, and he even manages to force her to fuck him! I don't know if I haven't tried it, but once I tried it, Rin found out that Daikoku's cock and her boyfriend's cock are very different! Her boyfriend just clicked a few beats and ejaculated, while Daikoku could make her orgasm for the first time, even orgasm countless times! Since then, Rin can't forget the image of Daikoku's cock, voluntarily offering her pussy to him, begging him to satisfy her lewd pussy...
