Driving Lessons.

This bit of fun took place during my years as a driving instructor.
I'd been teaching this young lass for a while and we got on well, and I learnt that her boyfriend lived over the water in Liverpool and was a train driver.
By this time we'd had sex several times, ( that started because she said I had lovely hands !! ) and she mentioned she was going over to see him after her lesson, so I offered to drive her there, she'd drive the main roads and I'd drive the motorway bit.
We got onto the M53 and headed for the tunnel 10 miles up the way, I mentioned it was a perfect chance for a blowjob, she didn't bat an eyelid, pulled down my zip, pulled out my dick and started sucking.
Have you ever had an orgasm at 60 MPH, you should try it sometime.
She swallowed my load about half a mile from the entrance, just enough time to put my dick away.
I was a gentleman and paid the tunnel fees. LOL.
