Make the anus the most sensitive part of a woman's body

Your rock hard cock is quivering and ready to be thrusted into your girlfriend's ass, and it does take some self-restraint to take up the pen once more and add yet another rule to the book, but you think of it as the final touch to the situation, the cherry on the cake, so to speak:

Old Rule: Many times more sensitive than the famous "G-spot", women have a mysterious "A-spot" in their anus, which, if stimulated, is guaranteed to produce very powerful and intense orgasms.

As soon as you put down the pen, you see Christina shiver, her face expressing a mixture of arousal and anxiety.

"Babe...", she whispers, her eyes wide open, "Uhm, maybe, we should not, I mean, can we maybe go somewhere else for this?"

You let your hands roam freely around her ass, and can't resist to play a bit with the end of the butt plug protruding from her anus. Christina moans and shivers again. "Why?", you ask her.

"Uhm, it's just, you know, I just said I've never done anal before, and that's true, please, believe me, but I did... you know... I have already, like, pleasured myself there, and... and... it's, like, like... I am REALLY sensitive there. I am not sure I can control myself, if you...", she bites her lips. "Oh gosh, Babe, but I want you so much!"

You place a kiss on her neck. "Sorry, Christina, but even if I wanted to - you do remember the rule, right? You got me hard, and, as you said: rules are rules."

She nods, shivering again in anticipation, arousal and a hint of embarrassement. "Rules are rules", she repeats in a hushed, whispering voice. You grin, because she obviously has no idea how true that is.

"Well, then", you say, and pull the butt plug out. As the device leaves her asshole with a soft plop, a deep moan escapes Christina's lips. It seems as if this simple motion has already stimulated the A-spot. You look at the gaping, inviting hole, push her panties aside just enough to lube your cock on her by now complely soaked pussy and then slide into her ass with a swift and conquering motion.

"O-ho FUCK!", exclaims Christina loudly, and makes almost every head in the room turn towards the two of you. It just needs two or three thrusts of you, and your girlfriend's moaning has turned into shivering cries of excitement and arousal. You feel her hands clawing into your body, her own body already out of her control, as she sighs and screams and squeaks. "OHMYFUCKINGODONTSTOPDONTSTOP....", she shouts, as you push your hard shaft again and again deep into her anus. There are a few shouts from other tables, some jeers and whistles - people seem to enjoy the show.

"Oh, oh, oh my God, I'm cumming, Babe", squeaks Christina, her voice sounding already hoarse. You blink in surprise, as it can't be more than two minutes or so since you started. Maybe you have exaggerated a bit with this last rule? Then again, it is fun, isn't it? So you thrust and thrust again, enjoying Christina's tight hole squeezing around your rock hard shaft, as you feel your petite girlfriend being seized and overpowered by an immensely strong anal orgasm, impaled on your dick and stimulated at her most sensitive spot. She is completely out of control, wailing and screaming and shivering. You're not sure you have ever seen the like - and most certainly not from anal sex.

As her orgasm slowly, very slowly, fades away, and Christina slumps on your still very hard and very erect dick, you are fully aware that she still hasn't fulfilled the "new rule" you had written into the book ("make him cum"). But you wonder again if you should not spice the situation up with yet another little rule...
