There's a part-time job where you just stay in a closed room for 100,000 yen! An erotic incident occurs between a strange man and woman in a room with the heating and heaters turned up to the max! (What should I do?! It's too hot, not just stuffy but I'm getting restless? I've got a stain on my private parts? Will my naughtiness be exposed?) Due to the abnormal heat, they gradually start to undress, and the sexually aroused man and woman, both half-naked, since no one is watching, end up having sex.
