‘Come on, you can do better than that!’ Erica barked, reaching both arms around behind the man mounting her and grabbing him by the backside. She ...ulled him deep into her with a deep moan, stretching out her sphincter in the process. As he began to withdraw in preparation for a second thrust, Erica dropped her weight down onto the sitting gentleman’s prick as hard as she could, then extracted herself far enough to pull the second man back inwards by his haunches. She continued this sawing. "We all had a little too much fun at that party. We got into the wine and…" "What, you all had sex with each other?" I said facetiously but angrily. "Yup." Dan shrugged. "But like I said, I had to the good sense to tell the guys to aim elsewhere before they went to…" "How could you" I was incensed. "Your own girl!" "Well I didn't do anything with her" he said, "We weren't even in the same room." I wasn't sure if I should feel relief at that. "So you didn't participate." I said, feeling maybe. As we got to into our make-out session, I whispered to her, “So how is this going to go?” I expected that, as before, we would do some “bare tit” next.She said, “I want you to go down on me first.” I hadn't expected that, and she must have sensed my hesitation. “Go ahead, it will be fine, no one can see. And, you'll find about those cute panties.”I got down on my knees and she spread her legs. The light from the screen illuminated what I needed to see. Her sheer white panties were of a generous. I was glad to see it was the ruler, it would hurt but it wasn’t too bad.I counted out the strokes as he gave them to me. Smack, “one”, smack, “two” until I had counted six. He walked to put the ruler away and I started to get up, thankful it was over and that it wasn’t as bad as I had expected.“We are done yet young lady, get back into position while I get the strap”My bottom already stung from the ruler, and now I was about to get the strap. I heard it whish through the air just before it hit.
