A while back I read a story about a brother and sister traveling together. The sister had to pee but had to hold it until she finally boarded he plane and when she finally was able to pee, the release of the pressure and the feeling of that she got highly aroused. A similar thing happened to my sister yesterday.
My sister 52(F) athletic build and looked like a 30 year old and myself 51(M) live about 75 miles apart and had to travel to a family wedding this weekend. My wife couldn't go because her mom had to have emergency surgery on the opposite side of the county and my brother in law couldn't go because he was sent out of the US for work. With the cost of the fancy hotel and flight costs my wife suggested that my sister and I just share a room so save money. Where adults and siblings so what could go wrong!
My family has always been close, huggers you may call it. Sis and I were going to meet at the airport and be on the same flight. The flight was close to boarding and sis was no where in site and wasn't replying to messages or calls. Finally she came rushing in and told me that an accident on the highway delayed her and she had to pee really bad once we get on the plane. We get seated, the pressure was staring to hurt her so once she could unbuckle and move she went to the restroom. She finally came back to her seat, sat down letting out a big sigh and just quietly whispered so no one else could hear said "omg I had to go bad, that was the best feeling finally relieving myself. I almost think I had an orgasm in there while peeing". I just kind of chucked not really knowing how to react to that statement and let it go.
Sis laid back and fell asleep, a little bit later she shifted, adjusted the arm rest out of the way and laid her head on my shoulder. A few minutes later she shifted again and was more of a cuddle position one had holding by arm and the other on my thigh. I laughed to myself and thought maybe she did have an orgasm earlier. Then erotic thoughts started going through my mind, wondering how she sounds when she cums and so forth. With her one hand just inches from my dick the other hand holding my arm, her strawberry scented hair against my neck I developed a chubby and hoped it wouldn't develop into a full erection. Tried to get my off of the situation while at the same time enjoying what was happening. Well I got a full erection and it started twitching.
After maybe 30 minutes into sis's nap she shifted slightly again, this time her hand almost touched my erect twitching dick. I could feel a little precum run down my thigh and thought oh no I don't want a wet spot. I need this to stop, but wasn't sure how to end it. If she wakes up my erection will be obvious. I felt a squeeze and a rub on my thigh and it suddenly stopped. A few seconds later she shifted and move off of me and toward the other side of her seat. It was a relief to have her move but made me horny. She once in a while would move her hand to the inside of her thigh and kind of make a motion like she was adjusting her pant leg and was acting a little restless. Soon they announced they would soon start the decent.
Sis woke up at this point and we just chit chatted the rest of the flight. We got settled in our room, refreshed up and went to the hotel bar to meet family, eat supper and go to rehearsal.
