During summer vacation, my sister brought her friend home, but there was an accident where the room's air conditioner broke and it turned into a greenhouse state! The wind from the electric fan was not at all cool, and I was sweating profusely, so I took off my jacket, lifted my skirt, and flashed my panties and nipples all over the place! I was so nervous that I got a full erection... Of course, my sister's friends found out, but they seemed to want to vent their frustration, so they pressured me to have sex with them, and I ended up cumming inside them multiple times, even with my sister!
