"I don't always get an erection, so why are you getting an erection today?" In my room in the middle of summer, when there is no air conditioning, I take off my uniform and cool down in my underwear from my childhood friend and female friend who find out that my erection is gone, and I'm sweating threesome

I have a girl I've been a childhood friend since I was little. We've been dating for so long, so there's no such thing as a man and a woman's shyness! On a hot summer day, my childhood friend took her female friend and took off her uniform as usual, saying, "Please let me cool off a bit," and forcibly pulled her female friend's uniform off, saying, "Because I'm used to seeing her," and forcibly pulled her away! As expected, I am not resistant to underwear from girls other than my childhood friend, so I am fully erect! I thought they'd be turned on, but the two girls were also fully open, and before they knew it, they had a threesome, sweating and sweating!
