I laughed, retrieved the bottle, and squirted a healthy glob into my hand. I painted her sphincter first, then pushed first one Lubricated finger and then a second into her colon while she groaned and gritted her teeth, trying to get used to the sensation. But then I brought my rock-hard dick up with my other hand and guided it into her sopping-wet pussy from behind. And my Lusty Irish Lover moaned in pleasure as I swiftly buried myself to the root.

For a few minutes, I slow-dicked her snatch while pumping two fingers in and out of her anus, adding more Lube every now and again. Then, I pushed a third finger in, causing her to stop and tense up, but after about a minute she went back into that meditative Zen state, relaxed, and allowed me to resume thrusting.

“Soo00... fulLLLL..." she mumbled into the mattress.

"Still wanna do this?" I asked in concern.

“Mmm-hmm..." Naimh opened her eyes, twisted her face back to me, and reached back with both hands to pull her own buttcheeks apart.

“Fuck my arse, Matty. Be the first one to ever fuck my arse. Be the only man to ever fuck my arse for the rest of my life.”

I choked up a little at that Last part. The idea of spending the rest of my life with the most gorgeous girl I'd ever seen and having her profess that kind of fidelity to me hit me like Cupid's arrow to the heart. She was inviting me to sodomize her, but I kept my cock in her cunt and bent forward, planting my Left hand on the mattress for support so I could get all the way down and kiss her lips.

“I love you, Matty," she told me sincerely.

“I love you, too," I replied with just as much emotion.

“Fuck my arse, Lover," she crooned, eyes glittering.

I grinned. "Yes, ma'am."

Coming upright again, I pulled my dick out of her pussy first. She got a fresh grip on her asscheeks, spreading them wide. With the bottle of lube in hand, I pulled my fingers out of her anus and gazed in wonder at the gaping dark hole that remained. I squirted another healthy glob of lube right into that gap, set down the bottle, and aimed my cockhead into her open sphincter. And easier than I would have thought, I pushed the first three inches through.

“Holy shii-aaaaaaaAAAAAHHHH!!!" Naimh's head SHOT up fast at the moment of penetration, and I could only imagine her eyes going saucer-shaped and her mouth gaping open. I suddenly wanted a mirror in front of her for the next time we did this so I could see actual expression on her face.

For my part, Naimh's asshole was unlike anything I'd ever felt before in my life. It was wet from all the Lube, but still not nearly as moist as a pussy. She felt tight, almost as tight as Belle’s virgin vagina, but less constricting at the same time. And it was HOT. Oh my gawd it was hot in her ass, and I groaned to feel such a uniquely amazing sensation for the very first time.

We were SO doing this again.

Meanwhile, Naimh groaned as she felt her colon being filled with cock for the first time. She kept her head down now, breathing shallowly with her eyes closed, trying hard to maintain that meditative Zen state. I worried a little that I was still hurting her, and even though this felt absolutely amazing to me, I was ready to stop at the first sign of her discomfort.

But she had a wicked smile on her face, all the way up until I hit bottom and had given her every last inch of Matty-cock she could take.

“That's everything,” I told her. "You've got my entire dick in your ass."

"Yasss..." Naimh hissed, still with that wicked grin. Only then did she open her eyes and look back at me.

“Fuck my arse, lover. Fuck my fuckin' arse."

So I fucked her “arse". I started slow, both letting her adjust to my thickness and absorbing the sensations myself. She got up onto all fours, a proper doggy-style position, and started bucking her butt back to meet my thrusts. We started speeding up, really building up a rhythm, although I would pause every now and again to ask her how she felt, getting answers like, "So full", "So good", and finally "I'm fine stop asking just fuckin’ FUCK me!"

So I stopped asking and focused on fucking. But I still kept talking.

So did she.

“Holy shit, Neevie, I love this. Your ass feels so fucking good."

“Fuck, fuck, fuck, fuck," she grunted. "You're so fuckin' big!"
