[Sebire (Sebire)] Muchisugi Gal no Bitch-ka Keikaku

Need translation here

Aaah! Cute! Nanaka, the girl, became a gyaru when she enter high school, but she doesn't change much inside. One day, she came to her childhood friend Ginya to teach her to be slut, because her gyaru friends has been talking about it and she can't follow their conversation. He does wonder what kind of friend she's been hanging out with, but also see a chance to have fun. After they got more used to it, Nanaka said her gyaru friend plan to introduce their sex buddy to Nanaka. That's when Ginya stops her, saying he doesn't want to give her to other man. Hasn't read the extra stories, but seems like they never be officially girlfriend/boyfriend yet, but they do enjoy the sex and plan on continuing their relationship. Flashback to few years ago, Nanaka asks Ginya about his type, and he answered he like lewd and experienced woman (probably without thinking too much about it).

Good shit here.
