He closed his mouth, swallowed and opened it again to show it was all gone. He moved back slightly and the second surprise of the day got me. His cock...had swollen up over five times the size it had been. It had been three inches. Now it was at least twelve inches or more. It was so wide it would not all fit in the hole. He pushed it partway in and I greedily sucked till it shot an absolutely huge load of cum all over my face and into my mouth. Such a huge load of cum, I had never seen. It ran. We were about half way through the lesson when “sir” sat down at his desk after giving us the work to do, now was my chance, I slid forward on my seat and slowly opened my legs, the cool air reached my wet pussy as my silky thighs opened, damn! He was not looking! I tried to do the work but I was not thinking about maths, I just wanted sex!! I felt like walking to the front dropping to my knees and sucking him off right there but that would have meant being expelled from school, I had to think. I went to her house; she welcomed me and gave me some snacks and cold drink. And told that the system is not working properly. We talked for some time. Even at this stage I never had any bad intensions in my mind. She was telling she was missing her husband (uncle) very much. She loved uncle very much and uncle also loved her very much. Then I went to the computer and was checking for the problem. Soon I repaired as I am good at computers it was a small hardware problem. I switched on the. I slid it down his long cock and it fitted very tightly. I spat on it to add to the lubrication and now I was ready. I took off my shirt, undid my belt, pulled off my jeans, then my boxers and chucked them all on the floor beside us. Clive looked hungrily at my fully naked body and I stood over him facing towards him. Not wanting to mess around I lowered myself onto his cock as if sitting on his lap, it penetrated slowly and I grunted in pretend pain as it was halfway in to get him even more.
