Riria Aizono changed her looks to that of a Gyaru since she wanted to fit in with the popular girls and boys, her Big Bro (unnamed) is a gloomy loner who at least had his little stepsister make him some company sometimes but now she hangs out with the popular crowd. One day when Riria brings another boy home to flirt Big Bro tries to make casual contact with his little sepsis but she shrugs him off. Big Bro goes to his room to furiously fap... then he overhears something coming out of Riria's room, shit, he is frustrated about his sister apparently getting some while he has no one.

However, it wasn't Riria getting funky with a guy, it was she pushing him off, Big Bro comes out to see Riria's fling left the room disgruntled, bro gets in her room to see Riria despondent, crying about it, Big Bro hears her out, saying she got too scared of the guy being too pushy, cutting him off so he got pissed and dumped her then and there; tough stuff, Big Bro just tells Riria not to bring randos to their house and getting in the way of his fapping, which makes Riria notice her Big Bro has an erection; Riria immediately forces herself on her brother, despite his protests but she says dildos don't have rights, Riria says she will use Big Bro to get some experience so she won't be left behind by her girl friends.

Big Bro was reluctant but his reservations soon fade away, he says gyarus aren't his type but Riria is seriously changing his mind, so Big Bro reverts the situation forcing himself on Riria, that's what she gets for making fun of him for being a virgin, well now he is about to lose it, and so Riria loses hers too, she berates Big Bro for being a loser who had to resort to doing his little stepsister but she isn't truly pushing him off... then mom comes by to check on what all the racket was all about, Big Bro hides and Riria tells mom everything is ok, mom says she shouldn't be making too much noise when bringing boys over, have some tact please.

The siblings resume their activities, Big Bro notices Riria isn't refusing him as much anynore... once they finish Riria mocks Big Bro once more but now says he will be her dummy practice so she grow mor experienced at sex, so she won't get cold feet whenever she gets a new cool boyfriend and he wants to do her.

However, Riria has settled into being a tsundere lil sis; Big Bro tries to seek her in her sleep, she pushes him off, to then come to his room and use him when thinking he is asleep. In the extra pages seen from Big Bro's point of view Riria has been teasing him more and more, accusing him of devouring her with his eyes, when in truth Riria is the one forcing herself on him, making excuses so she won't admit wanting to be with him; they go out but Big Bro asked why isn't she with her friends, the ones she threw him off to hang around once she became a gyaru... shut up! Riria says she will hang out with Big Bro, shamelessly going commando to force a reaction out of him, naturally Riria "punishes" Big Bro for reacting the way she hoped he would... Riria is suspiciously not the finding a new guy like she said she would, looks like Big Bro has a long time ahead as a dummy practice, THE END
