It's a hot day, and the air conditioner is broken. Yup, it's time for another steamy sex scene. This time, we're talking about a guy named "yukemotsu" who's been having sex with his "hot sweaty childhood friend" . Yep, that's right, the guy's back in the hot tub. He's super-excited to be having sex again, and he's even more excited when he realizes that his classmates are probably already watching him and his friend having sex. He starts to worry about what his classmates will think of him, and how they'll react if they saw them having sex in a public place like this. Oh, and by the way, this is the first time we've ever seen a guy so excited about sex.
