I've been experimenting with which what things I like to use to restrict My arms and make My hand veins pop. In this particular go at it, I decide to use elastic. It works so well! You can really stretch it tight around your forearm and when you wiggle your fingers, the veins are instant and HUGE! I focus on one hand at a time and don't alternate back and forth. I do get to both hands though, don't worry. Once the veins are at their best, I decide to run My tongue across them, because who wouldn't? They are too damn sexy not too! Look at how they pop!
