The Swap. Various

him to give in, however. I just tease him a little, barely sucking and only letting him feel the flicker of my tongue occasionally. Never giving him more than I have to, until he’s shaking and clenching his fists at his sides.

      But even better comes when I palm his tight, swollen balls and he can’t seem to stop himself lurching forward. Cock suddenly shoved deep in my mouth. Something like a gag welling up inside me.

      I have to lay my hands on his taut and trembling thighs to calm him, but it seems like he doesn’t want to be calmed now. He’s definitely making little gasping sounds and his cock is leaking steadily. Every time I swirl my tongue around the swollen tip I can taste the tang of his pre-come.

      But he still doesn’t go over. He doesn’t go over when I get my hand around the base of his shaft and rub in time with my working mouth, or when I suck hard while wriggling my tongue against that sensitive spot on the underside, the one that always makes Ryan shoot.

      Though the sounds he’s making definitely get louder. Little desperate groans and sighs that get shakier and shakier – oh, I could live for those sounds. Ryan’s got a delicious potty mouth but Sean, God. I’ve never heard anyone seem so desperate to come, or seen someone so urgent and shaky with it.

      It makes my clit swell and my pussy cream. Something which becomes clearer when someone runs a hand over my ass, before pulling the strip of my knickers to one side in order to get a finger in my pussy.

      I don’t even look back to see who’s doing it. I’m just grateful that they are, and more so when they add a second finger alongside the first.

      Feels amazing. Feels like something huge against my tender swollen flesh, exciting beyond belief in a way I can’t describe. For a brief delirious moment I think of those words I said to Ryan, of what I would have been if I’d never met him, and then I think of nothing else as I recognise his big hands on my hips.

      He doesn’t ask or say a word. He just drags my knickers down my thighs until they make a chain around my knees, and then while I’ve got another man’s cock in my mouth he pushes his own into my cunt.

      I groan loudly around Sean’s flesh, and he answers me in kind. In fact, we all echo each other, one after the other, like some sort of unholy round of verse singing. Even Kay joins in, as she watches with big fascinated eyes.

      After all, I’m sure she won’t be only watching by the end of the night. She’ll have my boyfriend panting over her, his cock slick and sliding in and out of her the way it’s doing inside me, right now.

      Though it won’t be the last time for her, even if it’s definitely going to be for me. I know it. I can feel it, over and around this thing we’re doing.

      This is the last time he’s going to hook his hands into the curves of my hips, and tug me back on his eager prick; the last time he’s going to put one big hand on my back to steady me; the last time I’m going to hear him tell me harder. Fuck back on me harder.

      Because I don’t obey him. I’m not greedy for his cock – I’m greedy for Sean’s. I’m impatient for Sean’s orgasm, sucking and licking and pawing him in places he’s embarrassed about me going. When I dig my nails into his firm round ass cheeks, he sways like someone drugged. He stutters out a no, don’t, when I do what Ryan taught me to – slide my hand back around and worm a finger to that soft smooth stretch of skin behind his balls, and press and rub until he’s quaking.

      Oh, there are so many things I’m going to teach Sean. He’s ripe for my tutorials: pressing against his perineum just as he’s struggling to come, a slick finger in his ass to make him squirm and blush, stopping and starting and teasing and starting again to make his orgasm extra lush.

      My orgasm is going to be extra lush too. Especially when Sean groans that he thinks he’s going to come, and Ryan tells him no, wait.

       Ladies first.

      And then he fucks into me hard until all I can hear is the firm wet slap of his thighs against my ass, the thick head of his cock butting against just the right place over and over. One long finger pressing firm to my clit, until I cry around this mouthful of flesh.

      ‘God, you made her come just like that,’ Kay says, in the breathy voice of someone newly infatuated.

      But she’s not wrong. My clit swells against his rubbing finger and the tingles already threading through me grow until they’re fit to burst. And then he says that’s it, baby, come on, and I obey like always. I suck hard and eager on Sean’s prick and shudder from head to toe.

      Of course the moment I do, Sean cries out. His hand goes to the back of my head and he urges his cock as deep as it will go, spurting over my tongue warm and thick. I remember the first time I ever went down on Ryan and he babbled on through the whole thing – how good and hot my mouth was and how – oh Jesus – he was going to do it in my mouth.

      But I think, for Sean, even the sound he made and all that grasping of the back of my head was a lot. Coming in front of people he’s not dating is a lot. Everything’s a lot. And I’m pretty sure Ryan knows that too, because his next words are like he’s read my mind.

      ‘See,’ he says, as he strokes my back. ‘She likes it when you talk to her.’

      And there’s such a strange fondness in his voice, a warmth that’s unlike anything I’ve ever heard from him. I suppose I should be offended that he’s talking over me, that I’m she, and yet I’m not. I want to say to Kay the same thing: be good to him. He likes it when you spoon up against his back.

      He likes it when you suck him long after he’s spent, and he likes taking baths together. He likes fingers in his mouth when he’s having sex, and blindfolds are his kink of choice.

      Though, in truth, I don’t know if I want to say. I know so well that he likes all of those things, but maybe I won’t tell you, Kay. Find out your own things. Could be that they’re different. I certainly intend to find out what’s different about Sean, all on my own.

      Already there’s something different. He doesn’t want to kiss me with a mouth full of his come. But he does want to spoon against my back, and bury his face in my hair, and so it is that I get to lie there and watch, as Kay finishes off my once-was-boyfriend.

      It’s been a year and a day since I last saw Ryan. I know it has, because Sean tells me as we’re driving up to the campsite. Number three thousand and eighty-five on the list of things I’ve learned about Sean in a year: he’s very good at timekeeping. Ryan was always awful at remembering days – he’d throw me three birthday parties a year to make up for the one he forgot.

      ‘Is your mind somewhere else?’ he asks, as we come to the turn-off.

      ‘Not really,’ I reply, but I’m lying. It is. Currently my mind happens to be on why I still compare Sean to Ryan, even after all this time. It’s something I think about a lot lately.

      ‘Nervous about seeing your ex?’ he asks, and he does it in that faux-jovial way he has when he’s nervous or trying to be someone he’s not. He thinks people want humour, lightness, not his crazy intensity.

      And maybe they do. Maybe they do. Some people do, some of the time.

      ‘No,’ I say, even though I can feel my heart fluttering against its cage.

      I don’t know why it’s doing that. There weren’t any heartbroken arguments, no awkward goodbyes. We jiggled the puzzle around – all four of us, even Sean.

      In the morning, Ryan had just said to me: You going with him, then?

      And I had replied: Sure.

      And then all of our things in swapped-around cars, Kay giggling: This is crazy! This is crazy! I love it!

      What’s in all of that to make me nervous? I’ve always wondered if Sean felt odd about leaving Kay just like that, but even the thought of him secretly continuing to love her all this time doesn’t make me nervous. I
