Yumizuki and Souichi are about to have sex for the first time. They're both so excited that they're about to do something they've always wanted to do, which is to get into a sexual relationship. They start off by talking about how awesome it is to be in love, and how they both want to do the same thing. They both feel like they can't wait to do it, and so they start to do what they'd always dreamed of doing: they'll just do it together, and it'll be so much fun that they won't even notice that it's sexy. They finally get to the part where they'm supposed to slap each other, and they both do it.
