One night at a hot spring inn where we stayed for a club training camp. The members who couldn't sleep gathered together and started drinking in their rooms... Although the members are usually serious, the presence of one slutty girl among them turned the party into a super high-tension one! The alcohol kept flowing, and before we knew it, everyone was spending it all on themselves! With the super serious girls, we played some naughty games that we wouldn't normally think we could play, but thanks to the alcohol and the slutty girl, our guards were down and we had a blast! In the end, everyone got along and had a big orgy!
