Chastity unlock, edged, ruined, denied with lidocaine numbing gel

My chastity sub has his cock unlocked from his chastity cage and I use my fleshlight and hands to edge him to a ruined orgasm which I promptly stop by squeezing the base of his shaft. Then I put on my latex gloves and plenty of lidocaine numbing gel without him knowing and give him a frustrating handjob that never comes to anything. He didn't know that his cock was getting less sensitive the more I stroked it, he doesn't get to cum that easily.
