Anal adventure

I rolled back next to Kirsty again, and let rip with another fart that had been brewing for a little while.

"Hmmm," said Kirsty thoughtfully, "my pussy is so wet and so full of your cum that it's running down to my bum. Look!" She lifted her legs up, raising her arse, and sure enough there was a trail of pussy juice and semen streaming from her cunt, over her anus and onto the bed. I looked back at Kirsty's face and she raised a cheeky eyebrow, licking her lips.

"Perhaps I need to have a closer look at that," I said, grinning. "Maybe if you could lie on your side?"

She rolled over, her bum towards me. One of her hands clasped one of her tits, the other spread her arse open for me.

"Oh, my boobs feel amazing," she said as she massaged her own huge tits. We had never, ever done anything as adventurous as anal before. My cock was still covered in her pussy juice so lubrication was no problem. I lined my hard dick up against Kirsty's shit-hole. "Hold on a minute," she said, and we paused as she passed wind again. "Now," she said, still revelling in her new-found freedom to talk dirty, "let's have your cock up my shit creek and start paddling!"

I complied, my dick pressing gently against her anal sphincter, which gradually opened wide enough to allow me entry. Kirsty gasped and moaned as I slowly slipped inside, and the hand that had been holding her arse-cheek moved around to her pussy. Kirsty normally thought masturbation of any kind was disgusting, so seeing her with one hand rubbing her tits and the other fingering her cunt was almost as much of a turn-on as the fact that I now had my cock inside her bum.

It was tight, so very tight, and felt different to her pussy. There wasn't as much lubrication, but the fluid that had flowed from her cunt and that was around my dick from our previous fuck was enough to allow me to slide in a little deeper.

"Hmmm, gently, slowly," moaned Kirsty and I began fucking her arse in remarkably slow motion. It felt great, but I couldn't imagine it was at all comfortable for her.

"Is it ok, babe?" I asked, reaching forward to massage one of her tits. She turned her head towards me, a big smile on her face, her eye looking dazed.

"Oh, yes, Billy," she replied, and kissed me. "Now go a little faster," she instructed. "Hmmmm, oh... oh yes. That's it." She giggled. "Your dick is up my bum! Yes! Now fuck it! Come on, Billy, fuck my arse. YES!" I gradually picked up speed and she seemed to get more and more excited.

"Ah, that feels so good!" she moaned. "Yes, shove that giant cock up my shit-hole, you stud! Oh babe! Oh, yes!" Her hand was rubbing away fast at her pussy as I continued to thrust my dick in and out of her butt. She gasped and slowed her masturbation as she came on her hand, but I hadn't come yet.

"Come on, babe! I want to feel your cum in my arse! Come on!" she said, and within a few more thrusts I was once again spurting my semen inside Kirsty's body - this time in her poop-shoot. We lay there for a few seconds, then I felt a strange new pressure against my dick.

"Get it out, quick!" said Kirsty. I hastily withdrew my cock from her arse - slowing to carefully get my dick head past her tight sphincter muscle. Seconds later, I watched as my wife's bum emitted another giant fart, this time bubbling with my cum juices as she did it.

"MMMMmmm, that was good!" she exclaimed, rolling over to face me again. "So much nicer than I thought it would be. We should do that again."

"Maybe not just now though," I replied as I lay back, exhausted - words I never thought I would hear myself saying about sex. But it wasn't over yet.
