A summer sleepover in an old folk house. Fireworks, watermelon, splashing around in the water... There are lots of fun things to do, but the summer weather will make you feel free in both body and Kokoro! A couple of friends have sex while out shopping, and they get so excited that they mess up their yukatas and start having sex even though they know their friend is on the other side of the sliding door. What's more, they're noticed and moaning right next to them. It's a summer memory full of all sorts of things.
