Cum at same time as Sara

I'm so turned on that I can already feel the cum building in balls. Before I can stop myself I let out a little grunt and cum in spurts all over my belly. I'm afraid for a second that I was too loud and Sara will have heard me, but I quickly realize that Sara is cumming too with a cute little grunt and a squeal.

I lay quietly in the bed next to my sleeping wife, afraid to even breath for fear that Sara will realize what I was doing. In the quiet I hear Sara's breathing go from the fast and heavy post-orgasmic pant, to a barely audible breath of wind. I begin to get drowsy from the quiet and my own post-orgasmic bliss. Slowly she raises the phone back up to her ear. She begins to whisper again, but now much quieter I can barely make out what she's saying. As I drift off to sleep I think, or imagine, that Sara says "they watched... Liked... Tomorrow will be fun."
