It felt weird worrying about being seen like that bysomeone I'd spent years sharing a room with. As I sat back down on mybed and started pulling a mus...ty smelling, but still wearable, poloshirt over my head, I heard soft steps slowly climbing the carpetedstairs.The first thing I noticed when I could see past the collar of my shirtwas his hair. It wasn't the first time I'd seen him in a ponytailbefore, but seeing it higher on his head made him look a littledifferent. He froze when our eyes met. Only Mark wasn't in his bed. I looked at Mary Beth and noticed she was wearing the same clothes that Mark wore last night. "Where's Mark?" I asked her."I am Mark, Ken, I woke up looking like her." She insisted."Look, Mary Beth," I said, "We ran this joke into the ground last night. It's too damn early to screw with people. You and Mark go somewhere and play your jokes on someone else. I'm going back to bed." I climbed back into my bed and pulled my covers over my head. It lasted maybe thirty. She pulled up the skirt revealing her lovely long legs and knickers and started pressing her fingers into her pussy frantically rubbing herself then let out a long groan as her head lolled back. Her mouth was open gasping for breath, her hand worked fast and in seconds she started to cum, her head thrashing from side to side and gasping for breath she groaned loudly. “Oh my God,” she whispered as everyone watching started talking about what was going on, all trying to see past each other as. MrsC did her best to take the knickers off without causing a scene but without success so she suggested a toilet break again I asked her if she was enjoying this and if she was ok to tease and play more, I received a long kiss and a yes and gracefully off she went twisted crooked knickers halfway down her back side, now it's my time to talk with Tony, he stood up to allow MrsC to pass him I moved into her seat to talk quietly to him, I asked if he was ok for time and if he was enjoying it so.
