Sewing a Submissive

Description: I've been on a sadistic streak lately, and tonight's session is no exception. after teasing you mercilessly and getting you rock-hard, i pull out a new machine to test what you can endure. what if i used a sewing machine on the tip of your erection? could you take it? would you enjoy it more than you can admit? the metal slides against your hot manhood, ready to test your physical and mental limits, but you take it, you take several sessions before you collapse into bliss.
