내 체육관 싱글에서 무엇을 입는가

Anyone who looks closely enoiugh when I am working out in my singlet will quickly mnotice I wewear nothing underneath except a shiny metal cockring, whjich is visible through the material. Here I am strwetching and dancing in one of my singlets. And, because nobody is around, I strip off for a bit of naked stretching.
