Heart Sound Breath play Masturbation In this video that is a custom, you can find an interesting experiment and breathing game. We use a special machine to exclusively record the heartbeat, the breath play with the bag on the head progresses from 3 to 8 minutes, and the heartbeat also speeds up and slows down, but in this experiment the heart speeds up more with excitement and masturbation, at the end when the air is exhausted inside the bag, the model takes out the remaining air with her hands, and at the end her playmate closes the hole in her neck more until she tries to reach orgasm. Thanks for your order Model. Alice Manson Fuckedfetish
