I hung there, exposed to them for their own sexual purposes. They held on to the straps and either fucked my pussy, mouth or ass as they pleased. Phil...ip always seemed to be the first one to take me in a new fashion and David and Logan took time out to move and adjust the cameras, often holding them for close ups or changing their batteries.One of the guys grabbed some nipple clamps and asked to put them on me. I nodded my head and it didn’t hurt too bad. They were tight, but my nipples were. We took our showers and headed back towards our bedroom.Steph stopped me and gave me a "shhhh" and pointed towards where Lexie and Terece were sleeping. They weren't sleeping. They were both locked in an embrace kissing while rubbing each other's pussy. What a way to start the morning. We walked, quietly towards them but they heard us and stopped. Lexie looked at us smiling and said they were feeling a bit horny and couldn't stop themselves. Steph told them to keep going, if they didn't. This sent Sophie wild and she was wriggling as Emma and I sucked, her breathing increased 10-fold and her body started to shake and spasm as she reached orgasm, “OH FUCK YESSSSS!” she cried out as she regained her breath.As we pulled up Emma looked at me, “You must do that to each tittie Uncle Bill, she will soon see the results” she said softly as her bestie recovered, I looked down and saw her panties were showing signs of wetness, Mmm I couldn’t wait for what was next.Emma idolised her. What have I gotten into here?” I asked myself. I was starting to get more than a little scared. I thought of her saying, “ Fook me, fook me hard, as if your life depended on it. It does, ye know.” I took the dress and the coins and hurried home. To be more accurate, I ran home like a bat out of hell. When I got there I made a cup of coffee and examined the coins. They were black with age, but they were definitely old Scottish coins. For a while in High school I collected coins and read up on.
