My pet begs me to let him cum, but I deny his orgasm

It’s been awhile since I’ve been really cruel to my pet. One of my favourite ways to torment him is with orgasm denial. After two days of locking him in chastity, I teased his cock till he was oozing and ready to cum. But, I didn’t let him explode. Even though he was begging me to let him cum – I decided to deny him of a huge, relieving orgasm and let his frustration continue into the week.
