My partner and I practise cum denial. We like to get as close to cumming then stop to feel the ache. Because we are denied so much we need to tell the other when to stop the stimulation. I like it so the moment she pulls her hands away I can feel some liquid cum ooze up my cock. If we time it right it will pool at the tip of my cock without the muscle clenching and it will stop the spurt.. Amazingly hot and achy. Her denial seems more physical more moaning and shaking humping up as I stop it….
