My sister-in-law is a masseuse and she massages my balls.
Today, I asked my sister-in-law for a massage. She's a professional masseuse and gives the best massages. I've always been attracted to my sister-in-law, but out of respect for my wife, I've always managed to control myself. But today was a difficult day for me, and I simply couldn't control myself. I really wanted to touch her breasts, because she touched my back and very close to my buttocks with her miraculously soft hands. My crotch reacted immediately, and I got an erection I couldn't hide, but then I saw her hands touching my balls. Obviously, she wanted some action too, so we had great sex.
