A girl comes over to my apartment, which is only a 1-minute walk from university, and asks if she can stay tonight. Because I'm weak-willed and harmless, the girl who is relaxed and carefree as if she were at her own house doesn't see me as a man. Of course, I'm too cowardly to reach out, so I secretly watch AV at night and jerk off... However, the girl who was supposed to be sleeping saw my figure! There's AV on the screen, and a hard-on in front of my eyes! A girl who was super excited by such a stimulating erotic visual suddenly did a no-hand blowjob! Furthermore, it developed further...!
