I woke up to a zipper being undone. I figured Clara had returned and was coming into the tent. I was facing her side, but I didn’t stir. I very slig...tly opened my eyes to see her come in, trying to find her way to her sleeping bag without waking me up. Clara glanced over at me to check that I was asleep. I barely had my eyes open, to the point that she couldn’t tell. She made sure I was sleeping one last time, and then removed her t-shirt and pants. She pulled out a night gown and put it on. The next time we checked their house while they were away we had another look in the biscuit tin and there had been several additions. There were pictures of mum in her one piece swimsuit with the top pulled down, in just her bikini bottoms, in only stocking and suspenders, standing in woods with nothing on, on naturist beaches and in public places with the front of her dress open. Looking at the locations we could see they had photographed in our house again and in my sister’s. In both she was. The movie was a bore and Phil and Janice didn't add to my mood. Phil wanted me to "get to know" his sister. She was just like he was; loud and clowning around. She looked just like Phil too; skinny with red hair and freckles. She even wore jeans and the same leather jacket as he did but she had a sexy ass and cute little tittie bumps in her t-shirt. Phil kept trying to make her talk to me but the way that she ignored me let me know that she wasn't interested.We stopped at a fast food place on. We then look each other in the eye and the look both ways says "I am about to fuck you". Immediately my dick gets a little hard and I squeeze her thigh and rub it a little. After about 10 seconds she comes to and moves my hand. I look at her and say don't fight it then go back to looking out my window. We get to the hotel and as we get off the elevator she turns to go to her room 3 door to the left of the elevator while my room is across the hall and 4 doors right of the hotel.HR- I enjoyed.
