“Oh, gross, you two. Stop it! I thought if I gave you three hours alone you’d be done that by the time I got back here. Ick!” And then she start...d to giggle.Jess disengaged from me, and stood to go over and hug her sister. I followed suit.“So, good afternoon?” Kate asked her sister.“Incredible afternoon,” Jess replied. Kate raised her eyebrows and left it at that. I was sure they would talk about it later. And I wasn’t sure I wanted to know what Jess told Kate.It was now time to get working on. I kept backing it up and watching it over and over. His cock was wonderful. There was one shot of my sister jacking him off and his cum flying out that just made me so wet every time I watched it and I watched it over and over and over.There was also a section of my sister sucking his cock. Oh, it was so hot. At the end, she pulled off him and he jacked his cock covering her face with his cum, then she licked the last few drops off. This was my thirteen-year old sister. And I'd only had my. I had roughlyfifteen minutes to be prepared for her. I opened the first of the fourdrawers of lingerie and girlie things that I had been instructed toacquire over the last year. I pulled out the full body, fishnetbodystocking and then stepped back and began to undress.My male persona was systematically pulled off as I removed my tie, mywhite long sleeve shirt and my trousers. I do, of course, wear pantieson a daily basis, per Mistress Purr's instructions. My work panties arealways to be full. It was. We found the whole experience relaxing and it was fantastic to swim ‘au naturel’ and get that all over tan. So each year on holidays in France we would seek out the naturist beaches where we could properly relax. On one such occasion I was reading a book while soaking up the sun and Joe was as usual in and out of the sea. He had been gone for a while and looking up I could see he was about 50 yards away talking to another couple. When he got back I asked him ‘what was that all about?’.
