.. a knock at the door interrupted them.Both snapped out of their embrace, looking quickly at the door, wondering who it could be. Karly saw in Rose's... eyes that she was pissed off by the interruption. Raising a fist and shaking it at the door, she growled to herself, Oh, fuck off, Layla. I was about to have Karly all to myself!Karly blushed, "Don't be mad. I was happy just to kiss you for a few moments. You have been on my mind since this morning. I guess we gave in to our, um... urges,. She looked up at him. “I have one other thing to tell you about me which may help you decide, one way or another. Mr. Sheffield, I am a masochist.”“What do you mean, masochist? You like being hurt?”“Let me tell you my history. I was raised in a rural family that was strict. As such, and being the mischievous person I am, I received a lot of spankings when I misbehaved. Mostly, it was my Mom that spanked me, but when I turned 12, my Father did the honors. When Daddy spanked me, it was different.. Robbie's cock must be inside her because he was now thrusting in and out of her and she was meeting every movement with those of her own, they are obviously greatly enjoying their first fuck. So was I and I realized just how much I was when I put my second finger up inside as I watched my son and his girlfriend."Oh, Robbie, this is so good, it just feels wonderful. I knew I'd love it when I finally had your beautiful, sexy cock inside my pussy. I just love us fucking. I've been waiting so. I..I couldn’t sleep….” She spluttered out as the orgasm shook thru her. A small finger was pushed into her tight arse up to the knuckle and started to wriggle. “What have I told you slut? How are you to address me?” the voice snapped. “I..I.. Im sorry Miss Sarah.. please not that…It hurts so much…arrrggghh…” she cried. “That’s better, now little one its time to get ready for the day. I am going to let you down and pull your new friend out of your disgusting little cunt. We will go the bathroom.
