Shizuna-chan & I

Going from a high school promise to date him in 4 years, to it cutting to him with his pants down and her giving him a handjob.
Shizuna-chan doesn't screw around lol.

Shizuna: "Want me to kill the lights?" ⁽⁽ૢ(⁎❝ົཽω❝ົཽ⁎)✧
Shuu: "NO!" （┛〃°　Д°）┛

Definitely worth the wait! Sexy Onee-san ending!

You know you read too many hentai stories when you had the same two scenarios in mind:
1. He has sex with his sister because she used the chance of him being sad from the rejection
2. Shizu is into femdom and secretly held him horny for four years

Maybe I have a problem who knows…

Worth that 4 years

Seems that even Hanafuda-sensei is capable of creating a story featuring a Sexy Onee-san FMC. And credit goes to MC for holding out for four years as he did (odds are, many others would have given up long ago).

Conclusion : "Well Isn't That Cute? ... BUT IT'S RIGHT!"
