That’s what cuckolds do

“Promise me you won’t tell Martin.”

“Tell him what?”

“About this.”

“He already knows. I told him six months ago that you and me were getting it on.”

“Oh he’s never said. No wonder he’s been acting strange.”

“Strange? I what way?”

“Telling me that he loves me all the time. Helping me to dress when I am meeting you.”

“That’s not strange Darlin! That’s what cuckolds do.”
