Learning to swim

I was at my aunt's place during vacations .I wanted to learn swiming from my female cousin who insisted I learn swimming in the nude.Wehad a private pool at aunt'place.I was told by my cusin she would start teaching next morni but I was nervous.My cousin was *****s older to me.On the fateful day she got all ready by first getting into a bikini and from topless to stark nude.So was my aunt.It was my turn until I also removed all my clothes but kept my hands in front of my penis.As a punishment I was told to raise my hands above my head and stand for 15 minutes.ThereafterI was made to do some Pushups along with pullups.
After all this,my lessons started.Nowadays,I am so used to skindipping that I always s2im in the nude.
