Karen's words erase your feelings of guilt.

You stay silent for a while, digesting her words. She had a good point. Sarah was amazingly hot and all yours for the next few days, no strings attached. You had fantasized about fucking her ever since you and Karen decided to open up; no sense in hiding your attraction to her from Karen. Especially after how hard Karen had cum watching you two fuck. You wonder how turned on you’d be when it was Karen’s turn with Jakob.

“You’re right babe,” you tell her. “I’ve wanted Sarah for a long time, no use in hiding it. I guess I still can’t believe how lucky I am to have you as well.”

“Umm that’s a good boy. Don’t worry about hurting me; you saw how much I loved you two fucking.”

“Oh yeah, you’re such a dirty little slut.” You squeeze her breast and whisper,” When Jakob comes tomorrow I want to be a slut just like you.”
