Ken offerred to teach Kelly and I to drive, in return for sexual favours. We both agreed to his terms and went for our first lesson. Kelly had learned to drive a few years ago, but had failled her test a couple of times. Carl had also failed his test twice, and he said he would come with us sometimes.

Our first lesson was about a week later. Ken asked Kelly to go first, so he could see what she knew, then it was my turn. I had driven a car before and so knew the basics. At the end of the lesson Ken told us we had done well and suggested that I would probably need about 20-25 lessons, and Kelly would need about 15. We parked the car and went to Ken's study. Ken told us to strip off, then he did the same. Just lloking at his huge cock harden got me really hard. He sat down and told us he wanted us to take turns in sucking him. Kelly took about half of his cock into her mouth and started to suck him, he was really wet and I could see that kelly was having to swallow almost all of the time. I was wanking while I was watching them. Then he asked me to suck him. I took as much of his cock into my mouth as I could, and started to suck him. Kelly was wanking me as I sucked him, and I knew I was going to cum quite quickly. Ken told me to let him know when I was going to cum as he wanted me to cum into his mouth.

After a few minutes I told him I was going to cum, he asked kelly to suck him, while he finished me off by sucking me. I stood up and he took my cock into his mouth. He sucked me really hard, and in a few minutes I could feel my cum pumping into his mouth, and could see he was swallowing it all. I then got back on my knees and took his cock into my mouth. I felt it start to throb and he took it out of my mouth, and started to wank. He told us to open our mouths and then he started to spray our faces with his hot cum, a lot of it went into our mouths. He actually produced too much cum for one person to swallow, so it was better this way.

We had lessons once or twice a week for the next 18 weeks, some of the time Carl was there with us, and he always emptied his cum into his uncles mouth, sometimes at the same time as me, and he also got sprayed by Ken.

After about 20 weeks Ken told us we were ready to sit our tests, so we managed to get them all booked on my 17th birthday.

I woke on my 17th birthday, I was very nervous, but having Kelly next to me was reassuring. We had been sleeping in the same bed for almost 6 months now, and had managed to keep it secret from Katie. We went down to the test centre, where we met Ken and Carl. My test was at 10.00. I Passed. Kelly had her test at 11.00, she Passed. We now just had to wait until 13.00 for Carl. By now he was a bag of nerves, but we told him he would be fine. We went to a nearby cafe while we were waiting. Carl and I went to the toilet where I sucked him off, trying to keep his mind off the upcoming test. It had been a few weeks since I had sucked him, and it was good to have a "normal" sized cock in my mouth. After he had cum, he told me he wanted to suck me. He sat on the toilet and sucked me until he had a mouthful of my cum. He swallowed it all, then we went back to join Kelly and Ken.

We went back to the test centre. Carl drove off on his test and when he returned he did not look too happy, but it turned out he too had passed. As we were driving home, he had told us how he had almost crashed as he burped and gou a load of my cum back into his mouth. When we got back, the 4 of us went to the study, Ken got his cock out and started to wank over our faces. He quickly shot his cum over us, he told us he had been so horny all day, that he thought he has going to burst.

Ken suggested that we all go out for a meal to celebrate us passing our tests, so Kelly and I went home to get ready to go out, telling Ken that we would be back at about 7pm.

As we were leaving Ken handed me a set of car keys, and told me I had the use of this car whenever I needed it, so we drove home to tell Mum and Katie the news...
