Okay, now we're back in the middle of the action again. This time it's Hiroyuki's sister, Mami, who's having sex with Hiroyuki. They're having sex on the eve of the new year, but they can't because they're not with their parents. Okay, so this isn't the first time they've had sex on New Year's Eve, but this is the first year that they haven't had sex since they were little kids. We're guessing that's because their parents aren't around to watch them have sex. The two girls are having sex anyway, because they want to have sex before the year's over. But they don't want their parents to see it. They want to do it because they have sex all the time, but their parents won't be around to witness it. The girls are all, "You're desperate, you're trying to squeeze my semen out right now" . And then they slap each other, and then they run off to get their "pants on" , which is a fancy way of saying "I'm not ready for sex right now, but I'm sure I'll be ready for it in the future." The girls finally decide that they'll just have sex as soon as the year is over.
