If anything decided to go tits up, I hoped to catch it in system and not in jump. When I completed systems check, I left Sam in control and inspected ...he upper deck, looking for anything out of place or loose. In the hold, I made sure all lockers and cabinets were still locked and closed. I went down to the lower deck and continued my inspection, again making sure things were secured.When I got back to the bridge to do a status check, only Katherine was there and she was looking at the display. Black body and black pantyhose with ballet flats at the feet while I was doing a bit the voyeur in general for all the girls during the dance lesson :-P and anyway I noticed the beautiful body of my sister and then the tight and well fleshy hips between the bottom of the black body and the beginning of the pantyhose and so when it was been the exercises they had to be done by the whole group together, I immediately got behind my sister and so, when it was necessary to do an exercise, for all. I said, “Hi you must be Frank, I’m John. We shook hand and he introduced me the blond k**, who was about 5’ 7” and thin, telling me this is Alex. Frank continued, “Alex will be doing the gutters for you as I have an estimate a few blocks from here and have to run an errand.” I guess I gave him a puzzled look and Frank said, “Oh Alex only looks like he is still in high school, he’s 19 and a great worker.” I was quite surprised and still had a hard time believing he was 19 but reached out my hand. Ten I told her that no one will see now you can show. She told hmmmm and opened her top 3 buttons and shown me her boobs inside her bra. I put my hands over them and pressed them and then she removed my hand and told me to drive. I asked her when next and she asked what? I told her shower? She understood what I wanted now and she told me she will let me know and I told her tomorrow I want and then drove my car and picked her son and reached home.Next day at morning after her son went to school.
