Erotic gymnastics for calm music

At the gymnastics class, a young girl lacked a thrill and she decided to undress slowly, which she had never done before. I turned on calm music, caught the rhythm and began to do exercises, smoothly moving from one position to another. I unbuttoned and threw back the bra. She took off her pants and only a mask on her face remained out of clothes, which gave the gymnast of eroticism.
