"This one's going to be very special, Doctor," the hard woman muttered.Paying little attention to his assistant, Dr. Greeley continued, "You must unde...stand, Mr. Merrick, that each of our young ladies must undergo a thorough examination before she is placed into the pool. It only makes sense when you stop to think about it."Jack continued to stare at the scene in the exam chair as he answered haltingly, "Well, yeah, Doc, but I wanted to..." He was too embarrassed to complete his. Over the next couple of weeks, the three of us became very good friends and we dated as a threesome most often. We soon perfected our technique of having our sexual playtime together. and we all three of us had a wonderful time.We attracted a bit of attention with me dating twins together. I had two male companions which made a few of my friends curious. We all became quite good at having our sex together and they organised everything to suit themselves which was more than comfortable with me.. "How would you like to try his ass now?" Jane asked, and I was snapped out of my reverie.To my displeasure, Nina withdrew.Jane did the same, and Ifelt Nina's cock at my entrance.I wondered for a moment how stupid I must look to her, as she nestled the dildo between my ass cheeks, by myexposed ass-hole.Not exactly manly, I thought to myself.But all such thoughts were forgotten as she entered me.The invading phallus stretched mealmost to the point of pain as it slid in.It was noticeably larger. I tie her arms at the wrists, throw the rope over a branch and pull it down until her arms are above her head. I keep pulling until she is standing on tip-toe, then I tie the rope off on the tree trunk. Next, I tie another rope to her left ankle, then pull that rope over the branch as well. She is now almost in a split, with one leg up and in the air, the other supporting her weight on her toes.Her body is already very red from the nettles, but I plan to add some nice welts to it. I will also.
