Masturbating with a Durex Play Delight vibrating bullet. It's a very small vibrator, but easy to hide and gives a very powerful vibration. ---- It's great for stimulating nerves just under the skin, on the testicles, and around the anus. Not long or wide enough to do much inside. Need to build up courage to buy a longer and wider vibrator! ---- Powerful vibration feels great when it's inserted, and the shape means it's great to hammer in and out.
