She was still living at home and had just finished school that day. she decided to go out celebrating with her friend and to start off the summer on a...drunken night. I sat at home that night as I was house sitting while my parents were out, it came to about 12 midnight and I got a call from them saying that they wouldnt be home. so I locked up the house and headed to bed and immediatly fell asleep. I got woken up by my sister unlockin the door and stubling in, I looked at my bedside clock and. John was sitting on a low stool in the bathroom and she bent over to wash his chest. The blouse she was wearing, without a bra, opened and she was showing a lot of tit, a lot.John saw the open blouse and thought Oh man does that look good she has a nice set of tits that’s for sure and no bra, man is she asking for me to touch them. She stood up and walked to the shower where she bent over to rinse out the towel, and she had on a pair of her daughter cut off jeans which were very short. John. Now we will come to story….When I reach 19 my father wants to join for family business and I don’t want to join bz this point I’m loving the life I have and I don’t want to be like my father and brother.

I’m always horny and there is a days that I fucked her 10 to 15 times for day.Even she and me went for two. Then she kissed my cheek and walked away. The small audience was too busy talking and watching the jazz band to notice what Alex was doing. I gave her suggestion some very serious thought. Enjoying the lounge's ambiance, my thoughts wandered to Alex in the pool. She came over and told me she was heading up to the pool in five minutes. She told me to give her fifteen minutes before coming up."Mr. Preston, I will understand if you decide not to." Alex kissed my cheek then turned and walked.
