My Little Sister Is the Best Fap Material

Miyu, my own sister, catches me masturbating to my favorite "sister" erotic game! She's always cool, straightforward, and a bit salty, but for some reason, she ends up helping me masturbate...! I began to cum on my little sister's skin and have her touch it! After a lot of skinship, now I can't bust a nut unless I'm thinking of her!

Genichiro Kazami's popular Web novel about little sisters is now available as a comic book by Hayate Asakura, a moe illustrator!
