When I pulled my top off, She smiled and said, ‘Well done, you did really well today,’ and then patted me on the back, where my bra strap ...as. ‘Oh, your bra has come undone,’ She said, and I think she undid it, and then put it back again. She turned me around and cupped my breasts in the bra and said, ‘Yeah, that’s a good fit.’ She looked at her watch and explained she needed to lock up soon and said it’d be quicker if she helped me get changed. I didn’t know what to do,. He’d talk, and at some point in the conversation point my way as his driver. I’d nod in acknowledgement. No doubt, more than one driver had his eye on my ride.

She was sorting out my armguards; a short set of straps that would go around my biceps and buckle into the safety harness. The idea was to keep your arms inside the car as it flipped mercilessly down the track. She had her mouth sucking the juices of her pussy off my dick and bobbing up and down until I would finish. The change of tempo from her nice rhythmic fuck to her “crazy for come” sucking blow job jolted me into a different groove. I have always found it strange how the same tempo, no matter what changes in positions, seems to be the key to the steady march to an orgasm. Her mouth being in the full horny state was bottoming out right from the start where normally a few minutes of sucking are. That was a nice squirt you shot on your mother. Or the one you managed to shoot way over your sister's head. How long do you think it was anyway? A new record for you?
