His dick has been shrinking since we started dating and that needs to change. I tied him up and told him that his dick had to grow to a specific size before he was allowed to cum. He was feeling extra sensitive and was extra whimpery today. I even teased him about cuckolding which he absolutely hates. Near the end he was writhing around in his restraints and he was so naughty, he came without permission after being edged only 10 or 11 times, so of course he had to receive a little bit of post orgasm punishment.
