His nipples were now directly connected to his cock, and touching them was essentially stroking him. Licking them? Well I could only guess based on his deep, delicious, addicting moans, that licking them was basically like sucking him off. Slowly, gently, sucking him to the mind shattering edge of endless, orgasmic bliss! You have no idea how hard it was not to reach down and start gently stroking his upper shaft when it started!! BUT, I did it! I made him cum by just his nipples, AND kept up the nipple overstimulation until every drop was on his tummy and dripping down his side! When he was “done” that’s when the obvious hit me… He’s not “done” until I untie him and say he’s done! And I wasn’t done until I stroked another toe curling orgasm out of his helpless body!
