My head continued to throb and pulsate as I looked to see a flow of cum seep from the cracks that had broken from her lips wrapped around the length o... my shaft. She was unable to take much more as some spilled free. It began to dribble down my shaft, towards my hairy ball sack. The head of my cock felt like it was swimming in water, due to the amount of cum I'd flushed out and her own saliva concocting a new mixture inside her mouth.Amy's head rose up, allowing my cock to plop free as it. I was pretty sure, and would have it confirmed the next day, that Jon and Lindsey were also having sex downstairs. The next day, we all laughed and joked about the previous evenings exploits but very little else was said. I was pleased and surprised there was real awkwardness. Lindsey and Jon had fucked and seemed flirtatious with each other, so me and Cara were more pleased with the notion that they might become a couple. One thing I wasn’t aware of at the time though and didn’t give any. “Hey guys, Charlotte said she couldn’t sleep. Do you want to play a game Charlotte?” I asked her. She looked at me and shrugged. “It’s a fun game! You know how you like fun games!”She copied my smile, “Okay! Yes! I like fun games!” She clapped her hands together, she was so excited.The guys were all watching now, interested in the game too. “Okay Charlotte! Pick one of your friends!”“Pick my friends?” She asked.“Yes, pick one of your friends here.” The guys got into it, putting their hands up,. All she said was “You will, just not right now. I want to have some fun with you first” as she winked at me again and her head just engulfed my cock and slowly slide down my shaft.I felt the back of her throat and her gagging a little, and I saw that she had only taken about ¾ of it. I was impressed and loving the feeling of it, so much that I almost exploded in her mouth. I guess she knew I was about to because she pulled my cock out of her mouth and told me “you’re really horny aren’t you?.
