Caught by Sister-in-law

My wife's sister lives with us. She is single and living with us to help out with the house payment while she saves at the same time.

I stayed home alone one Saturday while my wife went shopping with her friend. An hour into my solitude, my wife called to remind me about the laundry. So I went into the laundry room to get the clothes out of the dryer. I immediately noticed my sister-in-law's laundry basket filled with her clothes. A couple of her panties were on top of the pile. So I got interested in examining them closely. I picked them up of course. I got excited and got an erection.

Without thinking twice, I pulled down my shorts and wrapped my erection with her panties, then started stroking. A couple of minutes into it, the slight opened laundry room door swung wide open. My sister-in-law walked in on me with my pants down. She apologized quickly and backed out. But just as she did, she looked and saw that I had her panties wrapped around my penis. I returned everything back to her hamper, pulled my pants up, and walked out of the house.

I was so embarrassed and scared at the same time. Thinking she would tell my wife. So I hung around the yard for a while before deciding to head back in. When I got in the house the washer was running. Minutes later she came down from her room and I met up with her in the kitchen. I knew I had to apologize to her and no one was saying anything. My guts took over and flat out said, 'I'm sorry.' she responded with, 'I'm fine, don't worry about it. There's nothing to it.' I was relieved but still scared. So I asked, 'are you going to tell.' 'god nooh' she said. So we watched movies the rest of the day until my wife came home. She never stopped putting her hamper in the laundry room.
