In my head I wanted this to last all day, but in reality, I knew I would only last minutes being this turned on. I knew she was athletic but she was t...rning into an animal. She pulled off me spun around and sucked me deep into her mouth. Her head and hand were working my cock like a pornstar. I lay flat on the bed before she climbed on to me and rode me."This is fucking amazing John, FUCK ME!" she shouted.I wasn't in control., she was riding me and I had no control over how that pussy was. As I noticed this the feeling of being the odd one out left me with a feeling of despair, at any moment I would be ordered out to leave them to indulge in that sacred act, but there was hope, as they edged closer and closer, choosing to ignore me, no one was asking me to go, so I felt their excitement, I was caught up in their need, and my eying my brothers crotch did not trigger alarm bells, no nature was encouraging me as a female, and in my need, his penis became a separate organ, an organ. I whistled, making Melissa aware that I was awake. She turned around and gave me a peck on the lips. "Good morning sleepyhead. Now remember to drink lots of water, so you can pee all over me. I am going to pee on you too. It's gonna be so hot." All day at catering college I drank water, and had to cheat once or twice and use the toilet. By the time it was time go home I was almost bursting. When I got to Melissa's house I was let in by her mom but still had to wait for Melissa to arrive home.. I could only laugh and say “Yeah, I did.”I moved to lean against the railing because my legs were still shaky and getting mini spasms, and I could feel how damp and slick my swimmers were now, but then I could also start to feel the tail end of my orgasmic twitches syncing with the rhythm of the vibrator again and the pleasure level out, not dying off. I closed my eyes and let out a long, quiet “Ohhh…” and then suddenly I could sense that transition, almost like a pivot or click, when the tail.
