Sissygasm in a negative chastity belt

I, a beautiful sissy in red stockings, have locked myself in a negative chastity device. The feeling is so hot that I almost come alone. But I kept dildoing my beautiful big black cock in my hole until I had an internal sissygasm. The feeling of cumming inside is just awesome. The feeling when removing the chastity belt and the juice slowly flowing out is crazy. I love cumming like this.
