Shirtless confidence

So one time I visited a frat house and asked if it was ok to take my shirt off cuz I know it’s a pretty frat thing to do. They said yes so I did. They said you could even go naked around the house if you wanted to! Then the second time I visited I just went for it (taking my shirt off) because they had already said yes before, and they didn’t say anything at all and just continued on with the sandpapering we were doing. Then a few minutes later, because they said it was ok, I went in the bathroom, striped naked, then came out and showed up fully naked in front of the 2 guys I was with. It was the best and most freeing feeling ever!
