This happened about 20 years ago. My wife (Amy) & I went to the Outer Banks of North Carolina to visit her older sister and her husband. They had a beautiful 4 bedroom condo right by the ocean. My S-I-L (Laura) was just 2 years older than me. She had dark black hair (full Italian), and a huge rack. She also was a heavy drinker and would just about say or do anything you can think of. My brother in law (Bob) was also a heavy drinker. But he usually just passed out by the end of the night.
It's about a 9 1/2 hour drive from Pittsburgh to the Outer Banks. So usually I will wear pantyhose with a little support under my jeans to help stimulate my legs while I drive. I always love the feel of the nylon against my skin & cock. My wife is aware of my wearing, but not completely in touch with my full admiration of tights & pantyhose. There are even times I have gone out to gay clubs in short shorts and/or mini skirts, with high heels with a friend of mine. But that is another story to come later.
We arrived at Laura & Bob's condo around 4:00 pm on Saturday afternoon. Of course they were well into the day of beer & wine. After we unpacked the car, we settled down to join them for drinks. Since Amy & I haven't had much to eat during the drive, I wanted to go out and get some food. Bob & Laura were tipsy, so I offered to drive us to the restaurant. I have a great sense of humor, and Laura always liked being around me to better the mood. She was especially happy & having fun that night. I think it's because we finally arrived, in addition, her and Bob were have martial issues. So to talk to other people was a nice change of pace.
We ended up at a nice seafood restaurant. Laura was sitting to my left, Amy to the right & Bob was across from me at the table. Throughout the dinner, Laura was obnoxiously laughing at all of my comments. The whole time gulping down wine after wine. Each time she started giggling, she would slap her right hand against either my arm or leg. I thought nothing of this other than her big personality showing. The beer and wine was flowing the whole night. We left the restaurant around 10:00 to head back to the condo.
When we got in, Bob & Laura were totally smashed, and Amy was tired from the drive. I stayed up to catch up on some sports on ESPN. I figured since everyone went to bed, I would just throw some athletic shorts on and relax in front of the tv. I didn't even consider taking off my pantyhose, thinking I would just sleep in them & change in the morning.
