GVH-685 [Uncensored Leaked] Two innocent girls (my sister and her friend) who have just started to become interested in sex volunteered to watch me masturbate, and out of sheer curiosity, they grabbed my dick in their mouths the moment I ejaculated. Konatsu Kashiwagi/Rina Masako

Nanao, a dull office worker, is jacking off to a porn magazine he took from his teenage sister Rina when Rina spots him and asks him to "show me your dick, stroking it!" Even though she's his sister, it's embarrassing for him to jerk off and ejaculate, but Rina reflexively takes his dick in her mouth and swallows it! Later, his friend Konatsu comes over and swallows the cum from his jerk-off dick! In the end, Nanao is used as a toy by these innocent girls who are curious about sex, and is forced to participate in their naughty learning... #Team Leader P
