How an unexpected anal experience revealed our hidden and deepest fantasies

My wife and I have been married for 13 years, and we are genuinely happy together. Our sex life has always been active, passionate, and deeply satisfying. We make love three or four times a week, sometimes even more, and despite all these years together, the attraction between us has never faded.

About her, she is absolutely beautiful, about 5’7” tall, with long, silky dark brown hair that flows down her back. Her skin is incredibly fair, with a soft rosy undertone that becomes even more noticeable whenever she’s excited or embarrassed. What has always captivated me most is how naturally feminine she is. She has got gorgeous curves that make her impossible to ignore, a body that feels warm, soft and inviting. She has a delicious body with mouth-watering curves, full, heavy breasts that sway hypnotically when we have sex, a soft, well-proportioned tummy I love to squeeze, thick, luscious thighs that feel incredible when they wrap around me, and a perfectly round, full ass that’s impossible to ignore.

Before that night, anal sex had never even crossed our minds. It wasn’t a fantasy we talked about, it wasn’t something we watched, and it certainly wasn’t on our list of things to try. As far as we were concerned, our sex life was already incredible.

One thing we both loved, though, was using plenty of lubricant. We enjoyed the slick, slippery sensation it created, and over the years it had become almost impossible for us to have sex without it.

That night, we were completely lost in each other. I was pounding her hard in doggy style. She was on all fours, her back arched, her long, dark hair cascading over her shoulders and clinging to her flushed, pink-tinged skin. Her thick thighs were spread wide, her bottom raised and her buttocks parted, giving me a perfect view of her soaked pussy. I had already fucking deep inside her for a while. Everything was wet, her natural moisture mingling with our special lubricant, making every long stroke sound obscene and slick. I pulled back almost completely, then thrust in again with force... only this time, my angle was slightly different.

The head of my penis touched her small, tight ass. Before I could even react, a large part my penis had already slipped inside her pussy by mistake. The sensation was immediate and overwhelming, intense, unexpected, and completely different from anything either of us had ever experienced before. My wife’s entire body jolted forward. Her long hair whipped across her back as a startled moan escaped her lips, a mixture of surprise and something neither of us could immediately identify.

“Holy shit… babe…” she whispered, her voice trembling slightly. “That’s my fycking ass!!”.  

Her cheeks instantly flushed a deep pink against her pale skin as she turned her head to look back at me. I should have pulled back. Instead, I gave a slow, tentative thrust, just an inch or two deeper. She moaned louder, instinctively pressing her thick thighs and rounded bottom back against me. The sight of my glistening cock disappearing between her full buttocks was unreal, her pale skin glowing in the bedroom light, her hair swaying with every movement. I continued to penetrate her shallowly, perhaps five slow strokes, without sinking all the way in. Her breathing grew ragged, small moans escaping her with every thrust. I couldn't believe how good the anal sex felt! I could feel her trembling, pain, surprise, and unmistakable pleasure colliding within her voluptuous body. After a minute, I withdrew, my cock throbbing harder than ever and slid back into her wet pussy.

We ended up continuing as we normally would, but I couldn’t get that unexpected moment out of my head. When we collapsed, sweaty and exhausted, I kissed the back of her neck, brushing her long hair aside.

"I'm sorry... it was an accident. I didn't mean to..."

She turned her head, her cheeks still flushed and her eyes glazed with desire.

"It hurt a little... but damn... I liked it. The stretching, the feeling of fullness... I want it again."

We talked about it for hours afterward. She admitted the surprise had shocked her at first, but once the initial surprise passed, she found herself thinking about the experience far more than she expected. The curiosity stayed with her, and eventually she admitted she wanted to explore it properly.

The next evening, I sent her a few educational articles about safe anal sex. She read every one of them, asked plenty of questions, and then looked at me with a horny smile.

“Tonight”, she said. “This time I want to do it the right way.”.

We took our time. There was no rush. We focused on making sure she felt relaxed, comfortable, and excited. When the moment finally came, everything felt completely different from the accidental experience that had started the conversation in the first place.  First, I adored her body, I kissed her neck, sucked her full breasts until her nipples hardened and began to ache, and ate her out until she had two orgasms, her thighs trembling around my head. Then came the special lubricant bought for the occasion and a generous slap that foreshadowed the hard strike to follow. I slowly slid a finger into her tight ass, then two, moving them gently while she moaned into the pillow, her long hair loose, her hips rocking back for more.

When she began to beg, her bottom raised and her thick thighs trembling, I aligned myself. The head slipped past her ring with a wet, slick sound. She hissed, then let out a long, low moan as I sank in inch by inch, slowly, deeply, until my hips pressed against her full buttocks and my testicles rested against her wet pussy.

"Damn... you're stretching me so badly..." she moaned, her voice muffled by the pillow, her pale skin flushed from neck to ass.

I stayed buried deep inside for a full minute, letting her adjust, feeling her ass clench and twitch around me as if trying to pull me in deeper. Then I started to move, with long, deliberate strokes. She grew louder with every thrust. Her fingers gripped the sheets. Her back arched higher, pushing that perfect, round ass back toward me.

"Harder... please... fuck my ass harder..."

I gave her exactly what he begged me for. The room filled with the sound of her moans as I moved with her, my hand between her legs, touching her exactly the way she likes. I reached out and rubbed her clit, using quick, tight circles, just the way she likes it. In less than two minutes, she exploded. Her arched body shuddered violently. Her anus clenched so tightly that I nearly ejaculated. She was babbling incoherently, her pussy gushing over my fingers while her ass milked my cock.

I couldn't hold out much longer. I buried myself balls-deep and pumped thick jets of sperm deep inside her ass, growling her name as I filled her up. Since then, anal sex has become a regular part of our sex life. Sometimes quick and filthy. Other times slow, with hours of preparation and teasing, watching her pale skin flush deeper red with every inch I sank into her.

Even now, years later, I still think about that first accidental moment. The surprise, the shock, the curiosity that followed, it opened a door neither of us had expected to walk through. Without a doubt, it was the best “mistake” we ever made.
