It all starts when the girl sees her younger brother masturbating while holding some of her underwear. She tells him that she likes him as well and from there her brother just keeps having her do more and more sexual things while he takes pictures on his phone. He also eventually invites his friends over, too. The girl only does everything for the sake of her brother, and you get her thought process while she unwantingly does things to her brother and her brother's friends (by the way, it's not a turn on to here a girl complaining that the guy's penis smells horrible before she gives him a blowjob while you see the green stink lines coming off). The art is really simple as all of the guys are eye-less and hardly move at all, and the backgrounds are very boring. A lot of the girl's movement is also repetitive and the "camera" stays in the same place sometimes for over half a minute. There is also not a single musical note played during the entire thing until the end credits and the only sound at all is whatever the girl makes while blowing the guys or her talking.
There's not much appealing about this OVA. I skipped over the second half of the episode because none of it appealed to me, and I recommend you just avoid this hentai entirely.
