I would have gave up after the first cum. I'd love to have one of those indeed. Some evenings I cum a couple to three times and that would be perfect for me especially if it was one that was mechanical and didn't have to hold it. That would have me cum at least 3 to 4 times easily. I think my cock would get addicted very quick with that.i don't cum a lot like that but if I used that after so long my cock would probably get to that point especially now that I'm practicing relaxing the muscle of my cock the whole time I masturbate during each masturbating session.
I love seeing a cock being masturbated. If I were there and lucky enough to I'd masturbate the shaft of her cock bare handed and watch her hips trembling and wiggling with blissful enjoyment while sitting in between her legs with her arms bound above her head and masturbate the shaft of her cock through at least ¹4 to 15 cums
I have never seen one of those devices before and I don't think I could deal with it. It made Kitty give up at least two loads and I don't have that much to give.
