Recognised by the biology teacher - then there were sex less

It's been a long time, but as luck would have it, I bumped into my old biology teacher. He recognised me straight away and could still remember that I almost failed sex education. But a lot of time has passed since then and I was able to convince him very quickly that I had learnt a lot. I flirted around a bit because I thought he was horny back then and he apparently thought I was too. So we found ourselves in my bed again and I was able to convince him live what a bastard I had become. But I would never have thought that he was such a horny fucker. He banged me mercilessly in various positions. I have to say that 69 with his fat cock was more than hot and he licked me completely dry. It was really hot and I had several orgasms with him. So he wasn't just good in theory, he was a much better teacher in practice!
