My sister Rachel was getting married. We were all so excited for the wedding. Since I needed a tux anyway, I decided to go with them to get her wedding gown. While I was getting fitted for my tux, I saw my sister walk out in the most beautiful white gown. It was a full length strapless gown with lace around her breasts. There was also lace around the bottom. There was sequence along a floral design on the side. On her head, she had on a tiara that was just perfect for her. When I saw her fully dressed, I got immediately hard thinking how I wanted her to be mine.
We left the shop and returned home. When we got home, I immediately went to my room a closed the door. Or so I thought I closed it. I undid my pants and took out my hard 8 inch cock and stroked it rapidly while thinking about my sister in that wedding dress. It did not take long for me to ejaculate and I squirted cum towards my bed. When I finished, that was when I turned and saw my sister peeking in. Rachel immediately turned away. Instead of following her, I just sat there. My own sister just watched me as I jerked off.
I sat there for a few more minutes and cleaned up the room. As I was walking to the bathroom, I heard a noise coming from my sister's room. I noticed that her door was opened a crack so I looked in and she was on her bed. I also noticed she didn't have pants on. Rachel was playing with herself using a dildo and I can hear her moaning with pleasure. She was really jamming that dildo into her. Suddenly, she arched her back and I could tell she had an orgasm and her breathing started to level out. I wasn't sure if she saw me but I continued on to the bathroom to do my business.
Now I'm not going to lie, my sister is a looker. She is 5'6 blonde hair and gorgeous blue eyes. Her breasts are perfect at 34B and she curves perfectly at the waist. I have constantly fantasized about her but I never truly acted on it. I have seen her play with herself and we've seen one another naked but we never took it further though I've always wanted to!
Two days after the incident, it was time to go to our destination. Since we lived on an island, there were two methods to travel by; air or boat. My sister was a boater but I was a pilot. On this day, since our father was deceased, I asked my sister if she would fly with me instead of taking a boat. She accepted the invitation and we loaded her suitcase with mine into the car and drove off to the airport.
When we got to the airport, the plane was already sitting outside the hanger. We parked the car, got the bags out, and loaded the plane. I did my usual full preflight inspection and climbed into the cockpit with Rachel next to me. I started the engine and we taxied towards the runway. After getting clearance for takeoff, I revved up the engine and we lifted off towards our destination. It is normally a short flight but we were going a bit further north than normal. There were many islands beneath us but it was a breathtaking view. Rachel was looking around at the scenery below.
"This view is wonderful David." She said.
"Yes it is Rachel. This is why I prefer flying than to taking the boat."
"I can see that."
I can tell there was something on her mind but I did not have the guts to ask. Part of me didn't want to know the answer to the question that was on my mind. That was when she asked:
"David? Where you watching me the other night?"
I couldn't believe she actually asked that. Luckily the plane was on autopilot or we might've lost altitude. I looked at her and sighed. "Yes, Rachel, I was watching you the other night just like I believe you watched me just prior to me watching you."
"Yea I was." Rachel replied. "I couldn't help it. I heard you grunting and I just couldn't stop watching you. When you came..."
"You had to relieve yourself."
"Yea!"
