Want More Stamina?
Show me, ok? I want you to start teasing yourself.
While you're stroking, let your hands take on a mind of their own. Pretend a goddess of teasing reached down deep into your mind and possessed your arms, hands, and fingers, using your own hands against you no matter how hard you might try to fight it. Your own hands feeling like someone else's, but knowing your body like no one else ever could, driving you crazy, not in the ways you like most, but the ways that are most effective, the ways that are guaranteed to get you whimpering, your hips shamelessly thrusting for more and thrusting to get away at the same time.
After one or two minutes, we'll continue. Just feel those hands making you more and more desperate for a while and concentrate on it.
