I'm standing by the side of the bed. You're kneeling near the edge of the mattress, your feet, ankles, and a few inches of your legs overhanging. Your back is angled downwards, so that your shoulders and head are touching the bed, while your ass is the highest point.

I can hear how nervous you are from how rapid your breathing is. Every few breaths you take an extra deep inhale, clearly trying to get a hold of yourself.

I rest my left hand on your hip, and you flinch.

"Just, be gentle, okay?" you say, your voice muffled slightly by the pillow. "Remember this is my first time. Don't just try to shove it all in."

I bend down and kiss you just where your spine meets the top of your ass cheeks. I drag my fingernails slowly up the back of your right thigh. I let you feel the soft roughness of my beard tickling your skin.

"Shhhhh," I reply. "Trust me, baby. I want you to enjoy this."

I straighten back up and take a moment to just enjoy how fucking hot you look in the warm light of our bedroom. How sexy you are in that position; face down, ass up.

And what an ass.

Two rounded, pale, perfect semi-globes of the finest butt, full enough that even stretched in your current position there's enough flesh to curve outward from your body and overhang your legs.

I slap one cheek, my hand coming in from the side, hard enough that my palm feels instant heat, and watch the slight ripples that pass through you.

You gasp, and then giggle.

"Don't be a dick," you admonish me playfully.

"Ready?" I ask.

You take an extra deep breath, then let it out slowly.

"Okay. Do it."

I can hear the determination in your voice and it makes me smile. Your tone is that of someone who's about to get a tooth extraction, or have a bandaid ripped off.

"Relax, Mona. We're not at that part yet. I told you I'd go slowly, and I will."

We've talked our way up to this moment; me probably overly eager, and you probably overly cautious. You told me it was something you wanted to try -something you'd always wanted to try- but that you were scared because your friends had told you some horror stories of other people who had tried, and the things that had gone wrong. You even got to the point of asking a previous partner if he wanted to explore it with you, but he reacted badly, called it disgusting, made you feel ashamed.

I know that you might not like it, and I'm ready to stop whenever you tell me to, but I want you to at least have tried.

We've already fucked tonight. We've both cum. We're both relaxed and post-orgasm glowing. It feels like the perfect time.

I kneel down behind you, my face an inch away from your tight little asshole, and for a few seconds I just look at you, at it. From this angle both your pussy and your asshole are visible to me. Two perfect little fuckholes, each with their own individual appeal. Your pussy is always slightly open, never truly closed. I obviously can't see inside you, but if I had a torch and shone it there I would be able to look inside your body, even if it was just an inch or so.

Your asshole is very different. I know there's a hole there, but even here, even with my face and inch away from it, at best it looks like nothing more than an indent. I could shine the brightest torch there and not be able to see inside you at all. It is clamped tightly closed. I rub my dick in anticipation at feeling that serene tightness gripping and holding my shaft.

"What are you doing?" you ask, and I realise I've been staring for longer than I thought.

"Sorry baby," I mutter, sure that you can feel my breath there, on the most sensitive area of your skin.

I lick my lips to coat them with saliva, put my hands on your ass, one on each cheek with my thumbs a couple of inches either side of your hole, and gently stretch you, just a little, just enough to open that rosebud a fraction.

I place my tongue flat against your asshole, and lick you; a soft, wet, slow lick.

You murmur in pleasure. I've eaten your ass lots of times before, usually with you sitting on my face and me doing what you call Big Licks, from your asshole round to your pussy and ending on your clit, repeating the motion over and over while your grind and rub against my mouth.

I lick again, spreading my tongue so that it fills the little V of your ass crack. I keep it relaxed, dragging it over your hole, getting you as wet as I can. I continue like that, licking your asshole like it's the best ice cream in the world, gradually introducing the tip of my tongue a little bit more each time, pressing it into the dimple of your hole, increasing the pressure, stiffening it and pushing against you. It's amazing how hard the tip of the human tongue can get. When relaxed it is soft and velvety, but if you tense the muscle it becomes rigid, and strong, almost like a tiny little penis.

After a few minutes of gradually increasing pressure my open mouth is enveloping your hole and rather than licking you up and down I'm now flicking and pressing my tongue against you, exploring your opening more and more, pushing it into you until I'm tongue-fucking your asshole and my saliva and your pussy juices are soaking my beard.

You're so tight, and I'm not getting very much inside you at all, but I can feel you pushing against me each time I prod with my tongue. I can hear you moaning and breathing. And then I feel a vibration and I know that you're rubbing your clit while I eat your asshole.

"No," I say, and reach under you and firmly remove your hand from your pussy, pressing it into the bed and holding it there for a few seconds to underline my instruction.

"Why?" you complain, your voice breathy and ragged.

"Not yet." I say simply. "Soon, but not yet."

I stand up and, without warning, push my dick into your pussy. I sink it all the way in, filling you so quickly and so completely that you gasp in surprise. You try to rock back against me, but I place my hand on your lower back and stop you. I just want to fill you. I want you to feel my size and shape inside you, but I'm not fucking you.

I look down and your asshole is glistening wet.

I lick my thumb and place the fleshy part of it upside down on your hole, the rest of my fingers splayed out at the top of your ass. I rub it in little circles, over and around your asshole.

You begin to push back against me and this time I don't stop you, but I keep my arm rigid, bend my thumb against your hole, so that each time you push back the tip of my thumb slips inside you.

"Oh fuck," you grunt, feeling your asshole being properly invaded for the first time ever.

You need to want this. I don't want to force you to take it. I need you to enjoy the feeling. This is one of the points where I'll find out if you do. If you stop rocking back against my thumb I'll know you don't enjoy the sensation of having your most private little hole being stretched even just a tiny bit. I'll know that being fucked in the ass probably isn't going to be for you.

But, you don't stop.

In fact, you throw back harder, almost violently, until with each backwards thrust my thumb is disappearing into your asshole right up to the first joint.

I begin to flex it inside you, bending and straightening it in time with your rhythm, pushing against the soft lining of your asshole, feeling how gloriously fucking tight you are. I turn my hand slightly so that as my thumb bends inside you it's now pulling to the side. I'm deliberately stretching you, deliberately pulling on that opening, making it wider, flexing it, getting you ready for what's coming next.

And again I feel that steady thrumming vibration -this time on my cock- that gives away the fact you're playing with you clit again.

With my free hand a slap your ass hard, downwards, the high pitched sound ringing in the room.

You squeal.

"Leave your clit alone," I growl, pushing my entire thumb into your asshole to underline my point.

The vibration stops.

I hold my thumb in your asshole. I can feel the shape of my cock pressing against it through the membrane that separates your pussy from your ass. I flex my cock and enjoy being able to feel the movement from inside your body.

You've stopped moving now too. Little tremors are passing through your body.

I reach over and take the bottle of lube from where it's sitting on the table beside the bed.

I slowly pull my thumb out of you, watch as your asshole closes around it, not gaping even the tiniest bit.

"Can't you just fuck me?" you ask over your shoulder, the frustration obvious in you voice. "We can try anal another night. Tonight just fuck my pussy and do that thing you were doing with your thumb."

"Be quiet, Mona. It's happening, and you're going to love it."

My cock is still buried in your pussy, and I give you a couple of quick, hard thrusts before pulling it out. It's coated in your juices, and I love the thought of using your own cum as lube to fuck your ass, but for your first time that's not going to be enough.

I pop the lid off the bottle and squeeze a generous amount into your ass crack, just above your hole. As a wise person once said - when it comes to lube, there's no such thing as too much.

"It's cold!" you complain.

"Shhhhhh - I'll heat it up in a minute."

I watch the lube dribble down you. It pools and gathers and pauses at your entrance.

I press my cock against it and feel you tense through your asshole. I slide my shaft between your ass cheeks, getting it covered in slick, slippery lube. I squeeze a little bit more onto my dick, rubbing it in with my hand before putting the bottle back.

"Slowly," you remind me. "Please, baby."

I tilt my hips and push, and my cock begins to split and spread your asshole.

You tense and I feel you blocking me, stopping my progress.

"Just relax," I say, and maintain the same amount of pressure.

Another quarter inch disappears inside.

You're controlling your breathing, deep but rapid breaths, like I've seen women on TV who were giving birth do.

"I don't know if I can," you say. "I want to, but I don't think I can."

You don't use the word though. You don't say the word that we agreed meant I would stop instantly.

Same pressure.

Pushing.

My hands on your hips, holding you in place as my thick cock spreads your tight -so, so tight- little asshole.

It feels incredible. Even though I've got barely an inch in, it already feels amazing. There's a difference between fucking a pussy and fucking an ass. A palpable and definite difference. When you're fucking a pussy, most of the pressure comes from the entrance. It's like a ring of tightness that squeezes your dick and travels up and down the shaft as you push in and out. It absolutely feels good for the part of your dick that's actually inside her. It's warm and soft and wet and sexy and wonderful, inside the pussy isn't exactly tight. If you can, imagine a woman touching the tip of her index finger and thumb together so that they make a circle, and then imagine her wanking your dick with that. For this analogy, that's what fucking a pussy feels like.

Fucking an ass on the other hand, is like being wanked off by both hands.

An asshole grips and holds the entire length of your cock. It squeezes and presses in on all sides. It is tight no matter how deep you get. It isn't as wet, isn't as quite as soft, but when it comes to tightness, nothing beats fucking an asshole.

I push a little bit more, and the head of my dick goes right into your ass.

"That's the worst part over," I tell you. "Tell me how it feels."

You don't answer straight away. I like that you're giving it some thought, making sense of the sensations before you put them into words. I've always loved that about you.

"It's... it's okay," you say. "But hold it there just now. I need to relax a bit. I need to get used to it. I feel like I'm stretched wide open. It's not bad, but it is... different."

"Okay baby. Just take your time. Tell me when."

All I want to do is drive my entire length deep into you and fuck that asshole hard and fast. The pressure on my dick is almost unbearably devine. I need to fight the urge. I love you. I don't want to hurt you. But fuck. But fuck I want to. It is literally coded into my genes to fuck my cock into you. Every fibre of the animal inside me wants to hold you down and fuck you, ignoring your protests, ignoring your screams and just fucking taking you, and I need to fight hard to stop myself from doing just that. I need to slow my own breathing and focus on just staying still, with that one single inch of my dick buried in you, your quivering, trembling hole making it so tempting to just push and push and push and push and...

But I don't. Of course I don't. I love you.

"Try a bit more."

I push, but slowly, with consideration and love, and suddenly there's no resistance anymore. You've relaxed enough, and I've used enough lube, that my cock begins to just slide right into you.

I look down and watch it happen. I watch inch after inch of my thick cock disappear into that impossibly tiny hole. For the very first time in your life, you're being fucked in the ass, and I'm the one lucky enough to be doing it.

"Are you okay?" I ask.

"Fuuuuuck. It feels so big. Like I shouldn't be able to take it, but I can."

"You're doing so good, baby."

The inside of your ass feels so fucking good. There's the total pressure I mentioned before, but it is also soft. It's like the best hug a penis can be given.

"How much is in me?" you ask, and I'm so turned on by the excitement in your voice.

"About half. Want me to stop there?"

"No." you say quickly. "No don't stop. Fuck. Keep going. I think I can take it all. Does it feel good?"

"It feels so good baby. So fucking good."

Suddenly you reach between your legs and grope for my dick, gripping the half of it that isn't inside you. You run your finger around me just where we join, feeling how stretched and open your asshole is.

I don't go fast. I just keep pushing forwards, letting your ass open up and take me in.

"I'm so open! I'm so fucking wide open! Fuck, I like it. I actually like it. Fuck."

I love it when you swear during sex. I've noticed over our time together that the amount of bad language you use is directly proportional to the amount of pleasure you're getting.

"You're so tight."

"Am I? Does it feel good for you?"

"It's amazing. So good."

"Am I a dirty girl?" you ask. "Am I dirty little slut for taking it up the ass?"

I'm fully inside you now, and you're rocking back onto me, fucking my dick very gently with your asshole.

"Such a dirty girl," I say, starting to very slowly fuck you back. "A nasty little whore."

"Oh fuck yes! Getting fucked up the ass like a whore. Dirty, nasty little whore. Fuck your whore in the asshole baby. Fuck this filthy little slut."

I increase the speed just a little, making sure not to pull fully out of you at the end of each stroke. I love that you're loving it, but I don't want it to hurt. I don't want a good experience to turn into a bad one. I need to keep control of myself. But you feel so good. You feel so fucking good. I can't help myself. On the next stroke I drive it hard into you, slamming my hips against your ass.

"Ow!" you cry. "Not so hard baby. Easy."

I want to ignore you. Oh fuck how I want to ignore you.

I'm gentle with the next push, and the next, focusing on maintaining a pace that you can handle, but that also feels good for me. You're so perfectly tight, and what we're doing is so fucking basic, that I know I'm not going to last long anyway.

"Rub your clit," I tell you. "Rub your clit while you're taking a dick in your ass."

You do instantly. You're rubbing it so hard and fast that I can hear it.

"Fuck baby," you groan. "I can feel it in my pussy. I can feel your dick in my pussy. How? How can I feel it in my pussy?"

"I'm in your asshole," I remind you.

"I know you are, but fuck, fuck, I can feel you in my pussy. I can't explain. Oh fuck. Oh fuck. Fuck. I'm going to cum. Fuck baby I'm going to cum."

And you do.

"Fuuuuuuuuuuuuuuuuuuuuuuucckkkk!!!!!"

You cum hard with me fucking your little asshole, pushing yourself back onto me as you do, forcing as much of me up your ass as you possibly can. I can feel your entire body shuddering and shaking all around my cock, and as you cum your ass tightens and squeezes my dick harder than it's ever been squeezed before, the entire length of it gripped so fucking hard that I know I won't be able to resist it.

I cum.

I cum right up your ass.

I shoot my second load of the night deep into your asshole while you're still riding out your own orgasm.

I can feel pulses from inside your body running along my cock.

The physical sensation of it is incredible, but there's also a mental element that adds much to the experience.

Before now I've only ever came in your pussy or in your mouth (or over your face, your tits, your stomach, your legs) but never that third hole. I've never owned all of you. I've never claimed all of your holes. It might sound stupid, but up until that moment you were never fully mine.

And then you were.

All of you was mine.

As I pump and pump my cum into your asshole, and your orgasm passes through you in spasms so powerful that I can feel them in my balls, I know and you know that now you belong to me. We had discussed it. It was a large part of the reason why you were willing to try anal sex with me.

"I want you to have cum in all of my holes," you'd said. "I want to know that all of me is yours."

"Mine," I grunt as I fuck the last of my cum into you. "Mine. Fucking mine. My pussy, my mouth, my fucking asshole."

"Yours baby," you gasp. "All yours. All yours. All yours."

And then we fall forwards onto the bed, me on your back, my cock still held so tightly in your asshole.

We lie there, sweaty and happy and spent, for a few minutes. I can feel my cock begin to soften, but the position we're in means it stays in place, plugging your asshole, keeping my cum inside you.

"Fuck," you say eventually. "I mean... just... fuuuuck."

I kiss the back of your neck. Bite it gently.

"You're mine." I say

"I'm yours baby. All of me and all of my holes are yours."

"Forever."

"Forever and ever."
