This evening my cucky got another training session. To make it a bit more humiliating for him, I've decided that he will be naked. On his knees, kissing my legs, he couldn't hide his erection. I really liked to see how he reacts when I dom him. The more dominant I was, the harder his cock became, and it was fun to watch him being so vulnerable, while keeping my clothes on. When I made him suck a cock of my imaginary lover (dildo), he couldn't help himself and started wanking. My thrusts became even more aggressive, which he liked, and I rewarded him with a precum on my lover's cock. He's a good cock sucker, and it will be so much fun to suck a real cock together with him! The whole idea for this evening was to train him to be in a supporter role. I was having sex with my "lover", and he knew that I was going to cum with him. My cucky had to be near, focus on my pleasure, kiss me (and suck my lover), and under no circumstances cum himself. And he did a great job! For me, it was an intense orgasm, knowing that my husband was near, he was aroused, and, at the same time, focused only on me. Sacrificing his orgasm (and even ability to have sex with me) - all for me and my pleasure! As a reward, I've allowed him to lick my freshly fucked (and orgasmed) pussy after another "man". However, he had to wear a chastity cage to make it more submissive and humiliating for him. The mental aspect of cuckolding is very powerful, and my cuckold was very close to cumming from it. But I felt generous that evening and decided to give him a ruined orgasm. He was leaking a lot of precum (which he ate), and the amount of cum was impressive, too! The final mandatory step of his training was to eat all the cum. And he did it without hesitation. What a good little cucky I have!
