Bull or Boyfriend

Cammie is a married woman, but that doesn't stop Oliver from hooking up with her. Perhaps because she's married is what entices him. He learns that she wants him to be her bull since her cuckold husband wears a chastity cage and is unable to satsify her. Oliver is fine with all that. But when he learns more and more about Cammie's relationship with her husband, he starts to wonder what he's gotten himself into.  This is a 50, 000 word erotic novella that contains explicit sex and sexual descriptions.
It focuses on enforced male chastity, explicit sex, a femme domme-submissive male cuckolding relationship, group sex, sexual domination, lesbian sex, gay sex, complicated sexual relationships, and other sexually explicit themes and language that not all members of the public will enjoy. All characters are 18 or older. Originally published in five parts as Caged Meat. Excerpt: In the hotel room she had him get down on his knees in front of her.
Cammie liked being in charge when it came to sex.  "Good boy."  He smiled up at her. On the app fifteen years didn't seem to be that much of a difference, but Cammie carried herself completely differently than any woman Oliver's age ever had. They were playing a game and he liked it. Cammie stepped back and untied the strings keeping her dress closed. It wasn't a fancy dress, but something she could wear to work or on a date.
She liked that it was easy to put on.and take off.  She loved Oliver's reaction when she opened up the dress, exposing herself to him. His face lit up like he was a little boy on Christmas morning seeing a pile of presents all for him.
