Glove with Spikes for Teasing During Orgasm Denial

Merry Christmas and good evening everyone:hi: I wasn’t quite sure where to place this question or what exactly to title it… But since my wife would actually use it on me as a form of “torture” to tease me during times when I’m denied orgasm, the chastity section seemed like a good fit. What I need is a glove with “spikes” positioned on the outside of the palm and fingers. After waiting in chastity for a while, my wife will unlock the cage and use this glove to stroke me. I don’t want anything that causes bleeding or damages the skin; it just needs to be uncomfortable. Her rule is that if I can endure the “pain” until I cum, I earn my release. But if I tell her to stop because the pain gets too much, she’ll deduct that I haven’t waited long enough and put the cage back on:twisted: Ahhh, the sexual frustration:twisted::twisted: I’ve seen this style of glove online; they call it the Vampire Glove. However, before tax and shipping, it costs around $100. I’m wondering if anyone has found something similar at a hardware store or elsewhere? I haven’t tried it myself yet, but recently I wondered if perhaps taking a high-quality surgical glove, dipping it in some “safe” glue, and then rolling it in rice grains might work? :)
