She is shocked but curious

Kelly was shocked at what Amy had just said. Frank was short, fat, smelly, and the exact opposite of what most girls would find attractive; yet Amy was all over him. A girl she honestly had thought was too good for her son given just how beautiful she is. On top of that she never would have guessed her son was that depraved.

Kelly: “wow I guess I never would’ve imagined you and my son were soooooo… experimental.”

Amy: “well Frank is good at putting people in their place hehe”

Frank smirked: “If you are curious about it we could give you a demonstration. How about you hide in that closet and I call him out?”

Kelly was surprised at his response. She couldn’t help but be curious

“Hmmmmm alright I am interested…. He was always a bit unruly”

“Oh you won’t have to worry about that. Betas like him just need an alpha to make them realize how the world works”
