Exposed in front of my sisters friend

[JustHere10]

When I was growing up my houses AC broke and my family was on the poorer side. With that they couldn't fix the AC so we just had a bunch of fans everywhere. As you can imagine in the summer time July/August it gets extremely hot in the house. Because of that I had a habit of either walking around the house in shorts and shirtless but occasionally just in boxers and shirtless also. Honestly didn't think much of it at the time. So when I was 14 I walked out of my community bathroom in my boxers and my sister and her friend were standing right outside her room. My sister screamed and her friend just had her hand on her mouth trying to suppress her giggling. I was mortified as my boxers left super little to the imagination and ran to my room.
