Only one topless

[running_man]

Have you ever been topless among friends or other people with all other people (or most of them) being dressed "normally"? My question is addressed to males and females although I know it's not exactly the same in this case.

I remember a situation, many years ago when redecorating/painting a friend's apartment with a mixed group of people. Some of the men (including me) took off their shirts for painting (just for practical reasons) but later when we had finished and having some drinks I "forgot" to redress. As it was summer and warm it was easy to explain for me but secretly I enjoyed the situation so much (especially because there were also women in the group). And once I had decided to stay topless there was kind of "no way back" for me and so I stayed like this for 2 hours or so.

I also recall school trips (not as a child but in higher classes) when some of us tried to "impress" girls by being topless when they came into our dorm rooms to hang around with us. Sometimes we also challenged/dared us to take off our shirts in front of them. But in these situations I have never been the only one topless.
