Having fun with strange women's shoes is a really cool thing. Rub his cock on it - put it in your shoes, which is difficult with ballerinas, and rub the first drops of precum into the footbed. Also feel the sole of the shoe on the glans and stimulate the scrotum with gentle blows. My penis gets hotter and stiffer and I have to jerk him off until he squirts his sperm into my shoe. It's a shame that no one can wear it now.
