Incest roadblock aside, things have run so smoothly with my sister for so long, I haven’t really had to work.I could have tried to change her percep...ion of me. But I didn’t know what kind of ripple effect that would have - maybe if I wasn’t ‘innocent’ (by her warped definition of the word) she suddenly wouldn’t feel comfortable with anything we were doing.Maybe it would change stuff that we’d already done.Maybe it would break her.Besides which, I’d learned from Mom - don’t try to change these. "My God that is pervy - are you sure?" Paula questioned in astonishment.The whole room fell silent, I think we all realised that Simon fantasised about his sister and Paula getting it on."I've seen worse." Kerry blurted out. "In fact I can think of much dirtier things we could do for them." She said brazenly playing up to it.Simon fast forwarded to a lesbian scene."OK then, give us a show." He said, looking straight at Paula, daring her to back out.She gulped as she grabbed the back of Kerry's. She said he has a van that has a bed in it and we spent our entire lunch hour in it. She said after supper if you want dessert I'll take my pantyhose off and you can suck my pussy. I said I'd like that. I ate in a hurry and put my dish in the dishwasher then I sat and watched Andrea eat. She turned sideways in her chair and let her robe fall open showing me her nylon covered legs all the way to her crotch. I called her a tease. She said well it worked on Doug . After she finished eating I. It was a difficult task. We sat and then she said ” how are you planning to seduce me here?” I told her to wait and watch. Our waiter came up with our order and then I made sure that no one was looking at us and then just put my arm around her waist and was touching my bare foot to hers.Then I whispered in her ear ”I so want to lick your toes”. I could already feel her heart racing. Then I slid my hand a little above n brushed her side boobs above her dress and slid my hand back down to her ass.
