A pet-name given to a male partner, also known as a male-sub or sub-slut, by a male or female dom. Depending on the relationship or quality of sex, a "good boy" can be meant as a title of endearment used to help guide the male-sub through foreplay or sexual activity. As the dominatrix teases the male-sub more and more overtime, the term "good boy" can associate itself with sexual pleasure and rewarding behaviour, much like a relationship between pet and master.

Keep in mind that a "good boy" can be referred to as such in any sexual relationship, whether it be rough/BDSM/Masochistic/Mommydom/
Rape-roleplay, or gentle-fuck fetish-based, and can even be used for reverse roles where the male-partner is the dom and the female partner is the fem-sub.
"Alright, baby, flex your boy-pussy for me and get ready for momma to ravage you like the man-slut you are. That's it, such a good boy!"

"I'm the good boy in the relationship. Whether it's a rough-fuck or a cuddle-session, I'm a man-slut for acknowledgement."

A boy too good for this world, too precious and pure. He deserves a pat on the back and for people to ruffle his hair and give him gifts of adoration.
"Kaminari good boy," she said as she ruffled the hero's hair gingerly.

"Dude. Have you read the new chapter of DGM? Allen is such a good boy!" The guy went on enthusiastically.
