Testing Her Limits

She comes first. That's the rule. We don't have many of them, but this one is sacrosanct. Today might be the first time I deliberately break this, as I'm going to be pushing her boundaries and need to make sure she's got something to look forward to afterwards...

I tell her this, she looks a little confused but knows I won't brook any argument, and just gives me a little smile, with a bit of wariness hidden behind it; she knows what I'm going to be doing but not how it'll feel, physically or emotionally.

With this over, I lie on the bed, one hand gently stroking my cock through my trousers, and tell her to get undressed.

She looks at the open curtains and the light in the room and opens her mouth to begin to protest, but I silence her with a 'shhhh', there's only one thing I'm interested in her mouth doing for the next few minutes and it's certainly not answering back to me!

"Alexa, switch off bedroom light" I command and there's a little look of relief on her face as she stands up and starts slowly pulling her top over her head. She knows what I like to see her wearing when she's on her knees in front of me and a minute or so later, she's wearing just a pair of holdup stockings and a tiny look of nervousness behind the outwardly confident exterior.

'On your knees' I request from the bed and she obediently lowers herself down and runs her tongue round her lips to moisten them. As I stand up, I slide my belt from my trousers when I lower them and walk round behind her. This is the first time we've done this and she shivers a little when I wrap the belt round the wrists that she's tucked behind her back without me needing to ask. "Good girl" I let her know while stroking her hair with one hand and my now exposed cock with the other.

I walk round in front of her and she can't resist leaning forward a little to try and take my cock in her hot wet mouth, but I keep going and grab my gin before returning to stand in front of her, I don't need both my hands yet so sip it slowly as she starts to lick round my cock head, lubing it and my cockring piercing with her spit so that it'll slide in easier when one or other of us makes that move forward. After making sure that the head of my cock has been thoroughly loved, she leans forward a little and takes a couple of inches in her mouth, running her tongue round it, before moving back and releasing me and looking up. I know she's desperate for me to take over, but I just smile at her and she dips forward again, then again and again, taking slightly more of my cock each time until she's at what she thinks is her limit, around half my cock in her hungry mouth.

I finish my drink and set it aside, then run my hands through her hair. She knows what's coming, and as I tangle my hands in her hair at the sides and take a firm but gentle grip, she moans round my cock as I slowly pull her head towards me. If she had her hands free, at this moment she would be working the shaft of my cock with one of them, trying to keep my thrusts to as shallow a depth as she can manage, and strumming over her clit with the other, and I know this small but exquisite torture is making her cunt drip wet.

There's a slight gagging noise and her eyes widen as I reach her limit, so I pull back and let her gasp for breath round my cock before slowly pushing it into her mouth again. She knows I'm taking it slowly for her to get used to but she loves it when I loosen my self-control a little and start fucking her mouth, so I slowly speed up a bit, making sure to keep within her limits for now. She's drooling a little, trying to keep up with me, when I decide that it's the time to really test her and one thrust pushes the head of my cock right to the back of her mouth. Her lips stretch tight round it and tears start forming in the corners of her eyes as she struggles to keep her balance and tries not to pull away. I pull out with a smack of her lips and bend down to kiss her, letting her know that she's doing well, before straightening up again and pushing my cock between her lips as she gasps to regain her equilibrium. I fuck her like this for a little while longer and then pull out, "I'm not going to come in your mouth today", I let her know, and there's a little flash of disappointment in her eyes, before she starts wondering where I'm going to come instead.

I help her up and she goes for a sip of her drink after I loosen the bonds round her wrists, then silently lets me know exactly where she'd like me to come by walking to the end of the bed, getting on it with her head on the quilt and her arse presenting itself to me in the air. It's a perfect height.

I've never fucked her arse before without warming up with a buttplug beforehand, so I'm wondering if she can take it, but I can see she's hugely turned on, the wetness spreading from her cunt down the bare tops of her thighs. I drag a chair over to the end of the bed, settle down and start slowly circling her clit with my thumb, I love hearing her moan, and the moans intensify as my other hand firmly holds her arse cheek and the end of my tongue starts probing at her arse hole. She jumps a little and there's an instinctive millisecond where she pulls away but that's gone and she's wanting, needing me to keep going.

There's a slight sound of disappointment when I stop playing with her clit, but when she hears the click of the lid on the bottle of lube, she knows exactly what I'm doing with that hand now.

I keep my tongue circling her arsehole as I stand slightly awkwardly, kicking the chair away, and slather a good amount of lube on my stiff cock, then I'm upright and telling her to relax, breathe in and out, and slowly rubbing the head of my cock against her tight little arse. Not pressing forward yet, just skin to skin contact, letting her feel the ring in the end of my cock drag over her spit-lubed arse as we both moan with the sensation. "Relax, beautiful girl", I tell her, grip the shaft of my cock and slowly start pushing forward. It takes a few seconds, but there's a slip and a pop and a groan from her as the head of my cock slides inside her arse. I leave a couple of breaths for her to get used to the invasion before slowly and very firmly pushing forward, creeping inside her centimetre by centimetre until all of my cock is swallowed by her hungry arse and her moans must be loud enough for all of the neighbours to hear.

Almost as slowly, I pull out until only the head of my cock remains inside her and she's thinking that I'm going to take my cock out completely, but then I push back inside her a bit quicker than before and she pushes back against me until I'm buried completely again and I know she can take what I need to give her. I'm almost moaning myself when I let her know she's a good girl, I'm so turned on by now that I know I won't last much longer, the slick feeling of her tight ring around my cock is amazing. With my hands grabbing the flesh of her hips, I pull almost out then plunge myself into her arse, again and again until I feel the rising orgasm inside me and with one final deep thrust, with my balls slapping against her cunt, I unleash what feels like a torrent of cum deep in her arse.

She collapses forwards, releasing my slippery cock, and rolls over, presenting her soaking cunt to me which I drop down onto the bed and greedily attack with my tongue, like it's the last meal of a condemned person. I slide a finger inside her, then two, as her moans intensify, and my lapping pushes over the edge and she releases a flood of cum, drenching my beard and the bed, her hands then slowly releasing the bedsheets she'd been gripping on to so tightly and a wave of relaxation passes over her, with a look of satisfaction like the cat who got the cream.

It was the first time for a couple of things today, but we both know it won't be the last!
