Shower w*** next to sister in law
A few years ago we went to my wife's cousin's wedding. We started in a luxe camping place with tee pees and bell tents. I woke up in the morning with a stinking hang over and headed over to the showers to freshen up with my wife. My sister in law was there too. We all jumped into separate cubicles and my wife and her sister were chatting away about the night before. I took off my clothes and turned on the shower, feeling quite h**** that I was naked just inches away from my sister in law who was showing in the cubicle next to me. I started to w*** myself off. I didn't want it to be obvious to I tried to join in the conversation too. Within a few minutes I came in my hand...thinking about my naked sister in law next to me. I felt dirty and amazing all at the same time.
