DD ~Doko ni demo Isou na Hatsukoi no Osananajimi wa Do M de Seidorei Ganbou no Aru Hentai Musume Datta orz~

When your childhood friend decides to be your sex sl*ve, the two of you push pleasure to its agonizing limits! She's a virgin, but she's used her dildo on her ass so much by herself that it's just as good, too.
You're definitely going to enjoy your time together!
