Dulcie McKynan's life is about to change forever.

She's married to a handsome, ginger, millennial man who works in finance and likes to cuddle. She has a healthy sex life. She has a child and a dog. And she's always enjoyed a few "bull" fantasies.

So when her adoring husband, Miles, pleads with her to make all his dirty cuckold daydreams come true—and sleep with a seasoned "bull"—she reluctantly agrees.

Everyone's allowed a sexual fantasy, right? It's all supposed to be fun.

But now Dulcie has a serious crush.

She can't stop thinking about her "bull." He's the most beautiful man she's ever seen. He makes her feel sexy and dirty. She can't rest until she has sex with him again.

Little does she know… her husband is at home, falling apart.

Their marriage will never be the same.
