massaging my sister in law

My wife & myself went over to my wifes sisters. We helped her clean up around the house. At the end of the day we all got cleaned up and had dinner. After dinner Sherry(sisterinlaw) was having back pain, she poured us all a glass of wine to unwind and she asked me If I would mind giving her a massage, I asked my wife if she mined (since my occupation is a massage therapist) Kerry said she didn’t mind so I started massaging her, my wife Kerry was sitting on the couch watching TV. Sherry began to finally relax, I jokingly said I was not use to giving a massage with clothes on. My wife had agreed to that! Kerry went to the bathroom and got a towel for sherry. I suggested that she lie on the bed where she would be more comfortable. Sherry got up and went into the bedroom and To my suprise Sherry was lying on her stomach on the bed with a towel covering only her buttocks. I massaged Sherry for about half an hour she said it felt great, thanked me then STOOD UP letting the towel drop to the floor. I had just enough time before she turned around to catch a glimps of her nude breasts (which are about a D cup, alot smaller than my wifes) as she went into the bathroom to take a shower a wash the massage oil off of her body. My wife still turns me on with her natural red hair that flows past her wist line & her little red patch between her legs & lets not forget about those DD breasts of hers!!
My wife said that was a nice thing to do for Sherry and asked me if I would give her my special massage.
Now I began massaging my wife.
