Sakutaro, who had a complex about the size of his penis, bought a supplement online that said it would make his dick bigger and increase his ejaculation volume tenfold.
However, although the size increased, I found myself unable to ejaculate.
Even after having sex with my girlfriend for half a day, I don’t feel like ejaculating at all…I was absent from school for that reason, but my classmate and childhood friend Mizuki brought me some prints.
As expected, meeting him while he’s erect could ruin our friendship, so I urge him to go home, but he ends up being half-forced…
