FSDSS-136 — My Girlfriend's Sister, Sora Shiina, Is So Sensitive That She Seduces Me With Her High-Class Lingerie And Premature Ejaculation

Wanting to become a grown-up woman... Her sister is too dangerous but too sexy, but if she starts seducing you from a distance in high-end lingerie, can you say no??? It's impossible, right? So why not just go crazy and screw her like crazy without getting caught? Her sister is sensitive and has a premature ejaculation problem, so she climaxes over and over again in a short amount of time, so be careful not to cum too much in this reverse NTR!!!
