I hissed to Sam that her slip was showing and she made a quick adjustment to get it out of sight. As I turned away the door opened and we were invited... in.We started the presentation and I sat down on a chair at the front. I was careful to smooth down my black dress. It was knee length and rode up a bit as I sat down. I made sure I kept my knees closed up since I knew that we were being videoed and I may be in the shot.Sam started her part and after a couple of minutes I was aware that her slip. This continued over a few days until we arrived and the miserable mother told us her daughter wasn’t home, as she’s away for a few days, but that we could still go up to her room and play so we did, wasn’t long until Liam walked into the room and asked if he could join us.We started playing monopoly but it wasn’t long until he said it was boring and a k**s game, he asked us to play truth or dare, me and my sister were a little unsure, but he quickly said he would start.Started out innocently. He took a long breath, and tickled my neck a little as he exhaled. ‘I forgot how good you smell…very sexy.’ He put his arm around me underneath the coat and drew me closer to his side. ‘How soft your skin is.’ He said as he brushed my back up and down and started to lightly kiss my neck as he continued breathing heavy, obviously liking the sight down my top. I moaned as I felt tingles from his soft lips on my neck coarse through my body. He was wearing khakis and that soft gray sweater of his. "John? John, I need to talk to you; you've got it all wrong. Nothing happened between Robert and me. John, can you hear me? I know you're in there. Speak to me, John, please. Let's talk this over, please. You're making a terrible mistake," Sally called through the post box.I opened the door, but before she could say anything further I stuffed her handbag in her hand and then slammed it closed again. I'd already removed her credit cards and house keys from it.I watched as Sally went and talked.
