Practically you need not concentrate.” This was like a green signal for me.Meanwhile, theory written exams were completed and then we started prepar...ng for practical examinations. Now I asked her,” Shall I concentrate now practically.” And showed her practical anatomy book and laughed. She also laughed and said,” ok concentrate.. concentrate only on the book.” By saying this she opened the book and turned the pages and her pen fell down. Suddenly both of us bent down to take the pen and both. Each girl was told to wear a sexy set of underwear or a sexy piece of lingerie. My sisters and I had arranged the furniture so that they were all facing the TV/fireplace, but arranged them so that there was a big open space in the middle. After everyone we were expecting arrived, we locked the doors and called everyone’s attention. I thanked everyone for coming and explained to them that pizza was on the way and we would be able to eat after our first activity was over. I asked everyone. Stuck a finger in and pulled it out trailing a long sticky line of cum. Holy fuck! she said. Then I saw the hunger take over her face when she looked up at the guys again. No more blowjobs guys. I want you all to fuck me. Nobody moved. They all looked at me. Now! screamed Lisa. All the guys jumped. Steve was the first one to run to her aid. He helped her off the table, got her on her hands and knees and started fucking her. Billy ran around to the front of her and stuck his dick in her mouth.. It would turn me on very much if you fucked this dick. Why don't you just suck it first? Tease it?" Okay..." I crouched down a bit and wrapped my mouth around the black cock. It was much thicker than Tyler's and I liked the way it felt in my mouth. I sucked on it for a bit and I could hear the moans of the man it was attached to on the other side of the thin wall. I looked up at Tyler for reassurance and saw he was stroking his cock, which was rock hard. He was turned on and this pleased me..
