Ok, we'd been drinking. Of course we had, how else would this have gone from a silly game to something much more serious?

I bet my girlfriend that she wouldn't act the tart at the local pub. I wanted her to wear her shortest skirt, go bra-less in her tightest top, and generally mess with the heads of any male who happened to be in the lounge bar. If she pissed off wives and partners then that was all to the good. When we got home, I'd spank her for being such a dirty slut. She went for it. Her tits and hard nipples were highly visible and sent some regulars into cardiac territory, and caused a good few marital rows.

It got a bit out of hand when she returned from the ladies without her knickers. Think Basic Instinct in slow motion.

She was horny as hell when we got home and we postponed the spanking in favour of a good fucking session.

Then things escalated.

A couple of days later I challenged her to a no holes barred fuck fest, one where I came into her mouth, pussy and arse. I let her choose the order. She agreed, but only if I spanked her too. No contest. Mouth, spanking, pussy, then arse if you're interested (and I'm sure you are). We called this the Trinity.

When you add her giving me a hand job all over her face and tits to the Trinity you get the Slam.

What's the Grand Slam then? She is sitting opposite me in the pub, drink casually spilled down her front so that her tightest T-shirt is now sticking to her lovely tits. She keeps flashing her pussy to the couple opposite. I can see the wife's nipples standing proud so I reckon it's his lucky night. She's told me the order of events for later. The hand job is to be followed by a tit job as long as I coat her face. I just hope I've got enough ammunition.

Did I mention how much I adore my girlfriend?
