Naked, Danny leans on the pile of pillows pushed up against the headboard of your bed, legs wide open, huge erection jutting proudly into the air.

You shift backwards into his lap until you're pressed against his chest, his cock pushing into your spine. His hands rest on your thighs as you stroke your clit, readying yourself to receive him.

It doesn't take long and you use your fingers to help Danny inside, inhaling sharply when you realize how big he is.

How very different from Matt he is.

Matt is kneeling on the bed in front of you, his still-soft cock lying limply between his legs. He's staring at you, his brown eyes darker than usual - almost black now - as he watches Danny's cock thrust inside.

There's an expression on his face that you've never seen before. If you had time to think about it, you'd say it was a combination of lust and jealousy.

But you don't think about it. The minute Danny hits home, you close your eyes, ignoring Matt and just reveling in the delicious feeling of a thick, hard cock inside you.

He doesn't thrust at all; you told him at the beginning not to do that, laid the ground rules of this moment before anyone even got undressed. This is your night. This is all about you.

Danny leans further back against the mound of pillows, pulling you with him as his hands start running over your breasts, arms, neck, stomach, everywhere. Both your legs and his are splayed wide open.

You know Matt can see everything. Danny's erection buried inside you, stretching you open. Danny's fingers rolling your nipples into tight points. Danny's mouth sucking at your shoulder.

You continue to play with yourself as you lie back into Danny's embrace. His hands slide over your stomach and across your thighs to down between your legs, and he pushes your fingers aside to touch your clit himself.

There's a small noise - a grunt - something deep and guttural, and you open your eyes and smile at Matt. He doesn't smile back; his jaw is clenched, a frown marring his forehead.

You smile wider and push Danny's wandering fingers away from your clit. He doesn't seem to mind though, and his hands leave trails of dampness as they slide up over your stomach and ribs to close around your breasts again.

You return your hands to your clit and rub a little harder, never breaking eye contact with Matt, keeping the encouraging smile on your face until he scoots forward on the bed and reaches for you.

You grab his outstretched hand to pull him closer, placing his fingers between your legs. His touch is as tentative as Danny's wasn't and it amuses you because you've been together for a long time and, even in the beginning, Matt was never really nervous about sex.

You know he's discomfited by another man's cock so close to his own, especially his best friend's, but you keep smiling as you stare into his eyes, trying to convey to him that everything will be okay, that he has nothing to fear.

He offers a quick, weak smile in return, and his fingers flutter lightly on your clit, staying clear of Danny's cock but you press your hand against them, forcing them down, forcing him to touch Danny, forcing him to become fully involved in the experience.

Matt freezes for half a second, but you twine your fingers through his, guiding them around your clit and over the base of Danny's cock while your other hand stretches up behind your head to wrap around Danny's neck.

Matt's lips are slightly parted, the tip of his tongue between his teeth as he hovers uncertainly between what he wants and what he's afraid of. You're positive you can hear his heart pounding as he wrestles desire with fear.

Danny is pinching lightly at your nipples, rolling them into hard points, and his breath is hot on your shoulder. You drop Matt's hand, which is now touching you without your help, to stroke the underside of Danny's cock; he grunts in response and you know he's desperate to start thrusting but you refuse to give him permission. You don't want him to come too early.

You don't know if you want him to come at all.

Matt's cock is growing hard as he explores your clit, his nervousness giving way with a ghost of a smile which widens into a full smile as he twirls his fingers in that oh so familiar way around the edges of your clit. You tip your hips up even further and the new angle causes Danny's cock to slip a little, revealing more of the thick, veined underside.

Matt stares down as he flicks lightly at your clit, sending tiny spasms of heat through your muscles. Whether he's looking at you or at Danny... you don't know and you don't care.

It isn't about Danny. It isn't about Matt. It's about you.

You reach forward to circle your hands around Matt's erection and rub your thumbs across the damp tip. He growls quietly, a short vibration from the back of his throat, and with a tiny tug you urge him closer to you on the bed.

He obliges, willingly now, and you bend your knees to allow him to slide his legs between yours and Danny's. His hands run up and down your arms as you play with his cock. It's hot and heavy in your palms and you touch him everywhere, sliding your fingers down the shaft, stroking the base, tickling the underside.

It responds enthusiastically, straining desperately towards you, and you look up at Matt who's staring silently at you, his eyes dark and glittery in the pale glow from the bedside light.

You let go of his cock to touch his face, using your fingers to pull his head down to yours. The first kiss is soft and quick and slightly wary; you assume it's because you're impaled on Danny's cock and he's having issues with displays of affection while his best friend is fucking you.

And so the second time, you kiss him hard, pressing your lips to his, running your tongue gently along them until he opens his mouth to allow you entrance. Your hands curl around the back of his neck and you tease his tongue with yours, pulling him against you as you lie back on Danny once more.

Matt shifts closer and uses both his hands to push his cock into you. You inhale sharply and dig your fingernails into Matt's shoulders as you feel your body stretching to accommodate both him and Danny. And then he's fully inside as well, and the feeling is a thousand times better than you imagined.

You are full. Not painfully so - but uncomfortably. And then, really only slightly. But you're not moving either, just sitting perfectly still because you know even if you move just a tiny fraction this way or that, the discomfort will increase tenfold.

So you just sit there with your legs wrapped around Matt's waist and your head buried in the crook of his neck as you try to get used to the feeling of two cocks inside you. Danny nestled snugly against Matt, both filling you up so completely that you feel if you even breathe too heavily, you'll rip apart.

So you sit. And breathe. And just feel.

There's silence in the bedroom and both men wait for your signal. It doesn't take long before you're used to the burning heat inside, before you're comfortable with the two erections that are sending you hard and fast towards orgasm.

You lean forward, enough for Danny to let go of your breasts. His fingers curl over your hipbones, holding you firm as you wrap your arms around Matt's back. Danny's cock shifts inside you as you move, the soft ridges scraping around your flesh. He thrusts forward with you and, unexpectedly, you come. Violently, loudly. You gasp for air as an orgasm rips through you like a never ending electric shock.

Matt's hands stroke your lower back as you cry out into his chest. You can feel the base of his cock pulsing against your clit; hear his voice, as it whispers your name, half strangled and desperate.

You lift your head to look at him and silently, with nothing more than a twitch of his eyebrows, he begs you for his own release. You nod quickly and he breathes out in a rush, and lets himself go, exploding inside you, exploding against Danny.

The rush inside you is enough for your dying orgasm to swell and repeat, and you cling to Matt, your fingernails digging into his spine. He drops his head to kiss you, his tongue playing gently with yours, his teeth pulling at your lower lip.

Almost immediately, and without permission from you, Danny comes as well, grunting like an animal, throbbing against Matt's cock. You close your eyes and whimper, a pitiful moaning cry, the sensations both inside and outside draining all the energy from your body.

Matt's hands rub tenderly across your back and when you press your ear to his chest, you can feel his heart beating. Tears quickly slip from your eyes, wetting his skin. Danny says something to Matt but you don't listen.

All of a sudden you feel disconnected somehow. Not really there; just someone looking at a woman sitting on a bed with white cotton sheets, being fucked by two men, one she loves with every part of her being, one she… doesn't.

Maybe it's the pressure inside, maybe it's the heat of two men encircling you or maybe it's their hands running over every part of your exposed flesh. Maybe it's just the pain causing you to feel so detached from the proceedings. Or the post orgasm weakness quickly enveloping your body. The sudden realization that Danny didn't use protection, that none of you had mentioned it.

Maybe it's just because it's a fantasy you never wanted to have happen.

Danny doesn't feel like Danny. Or anyone else for that matter. He's just an object. A spare cock in a relationship of two where the relationship is slowly fading away. But there are hands on your breasts and they're not Matt's. They move differently over your skin; they're rougher and larger. Teeth are biting into your neck from behind. As much as you don't want him there, he is and there's nothing you can do. You can never go back.

You close your eyes and cling to Matt and say nothing. It hurts when Danny's cock slips out. His hands have stopped their stroking and his body is no longer warming you from behind. He and Matt are saying something else to each other and you're still not listening. You press your hand between your legs, feeling the dampness seeping onto the sheets, not caring that tomorrow there'll be a stain and you'll have to clean because Matt is useless at domesticity.

The front door slams and you roll over onto your side and curl your legs up to your chest to stop the ache. The bedroom light, an orange haze against your closed eyes, is switched off and someone is behind you on the bed, shifting across, pressing up behind you. Warm. Hard and soft at the same time. Matt. His muscles molding to yours, the familiar curves of his body fitting into the curves of yours.

You're rapidly approaching unconsciousness, and can barely move anything more than a twist of your head to stare at him. He stares back and then smiles, a tiny twitch of his lips, and drapes his arm over your waist, fingers stroking your stomach. You press your face back into your pillow and close your eyes again.

When you awake, it's morning, and a hand is probing between your legs, a finger stroking lightly at your tender flesh and you shift your hips backwards towards him, feeling his morning erection, hard and hot, against your thighs.

It's the position you always wake up in. Matt behind you, nudging you with his hands and his cock as you wake up, seeking permission that he knows you'll give.

You yawn, stretch one of your legs giving him entrance, and he eagerly slips his fingers inside you, his thumb rubbing gently at your clit. As your arousal increases with his skilled movements, you stare at the space in the bed between you and the edge of the bed. It's strangely empty, as if the bed is too big for just you and Matt, as if it's missing something. Someone.

And then you remember.

The sheets there are cold with no indentations anywhere that could have held Danny. Still groggy from sleep, you wonder if you should ask Matt where Danny is because you can't remember what time he left.

But you won't ask. Matt's morning erection is growing as his fingers thrust into you, getting you ready, and his teeth are nipping your shoulder. Your body is tingling with the first signs of orgasm, and his hand is moving too fast and feels too good for you to stop him so you give in, clutching your pillow as you come.

Before the waves of your climax even being to slow down, he's pushing your thigh up and sliding inside you, cock throbbing in anticipation as he begins to move.

But you feel empty. Unfulfilled. You want to ask where Danny is but you won't. It was a brief moment, a flash in your life where your body asked for something and your mind gave in, and you feel like you've deceived the man you love, and so you won't think about it again.

It won't be mentioned, won't be discussed. It was mind-blowingly erotic, so incredibly arousing, something you had never dreamed of before, and now you have to convince yourself that Danny was never really there. Convince yourself that what happened... really didn't happen.

And the guilt you feel over having betrayed Matt, even though he'll never understand why you wanted to do it, tears a tiny piece of your soul into painful, irretrievable shreds.

He's still thrusting forcefully into you, his cock twitching with impending release and you bury your face into your pillow as he finally comes, and you can feel his heart pounding through his chest against your back, hear the echo of air as he roars with fulfillment.

And you just want to cry.
