I drip baby oil over my wife’s ass cheeks and message them before dripping a teardrop on her until now, forbidden hole giving it a light rub with my thumb. For years I have been asking Victoria for anal but all I have managed is a bit of ass play and even that wasn’t well received.

I would like to say that this is a little Christmas present, that the season to be jolly had thawed my frozen, frigid wife but sadly, that isn’t the case. She has no choice but to unwrap her ass to me because I have discovered that she has been fucking her sister’s husband Jack.

Put it this way, if her sister Georgina found out about their secret fucking trysts, Victoria’s life wouldn’t be worth living. Let me think about what characters these two cunts would portray if we were getting in the Christmas spirit: The two ugly sisters in the Cinderella pantomime.

They are not ugly to look at, I will give them that but inside they are as horrid as a wizened, nasty little elf. All twisted and broken and ridiculously competitive with each other. If Georgina uncovered Victoria’s little secret, she would tell their father, and my slut of a wife could kiss goodbye to her vast monthly allowance and would probably be written out of his will.

There is no love lost between Georgina and Victoria at the best of times so any chance to fuck her sister metaphorically up the ass would be a dream come true for Georgina. So, to get fucked up the ass for real by me to bargain my silence is the most preferable option for Victoria. So here she is, my wife offering a very reluctant Christmas present.

I want to just push right in and teach her a lesson but to be honest, I want to prolong this experience as long as I can and revel in the fact that this is pure torture for Victoria. I feel a kind of snap on my cock as I enter, not a snap that you can hear but I don’t know how else to describe it and her ass clamps tightly over my cock which is now like an iron rod encased in velvet.

I ignore her muffled cries of pain, or it could be ones of pleasure. For all I know Jack could have been doing this for months at his leisure. Thinking of my wife doing this with that smarmy cunt fills me with a sexual anger I didn’t even know I possessed so now I can’t be bothered taking this slow and sparing Victoria of any pain, plus time is of the essence.

I pump her hard until I shoot my load inside her and I hope it stings as much as her betrayal has stung me. Slowly I pull out and reach over to the bedside table and pull out a tissue from a box decorated with snow and stars, the usual Christmas nonsense and wipe the end of my cock. I toss it in the basket at the side of the bed.

Victoria lies down on her front, her face still in the pillow. Eventually she turns and looks at me and with a quiet satisfaction I see that her mascara has created two streaked lines down the side of each of her eyes.

‘Are we quits now, Alistair?’ she says between gritted teeth, not a glimmer of remorse or apology in sight.

I give her a wry smile and then right on cue the sound of someone banging on the front door resounds around the house.

I slip on the terrible Christmas pyjamas Victoria has bought me with a smug, self-satisfied ease and mess about arranging my cock. Once I have straightened myself up I smile.

‘That will be your sister. Do you want to let her in or shall I?'
