A/N: So… Donnersun wanted to prompt something for the Twikinkfest about cross-dressing Riley in something pink and frilly but it was too late for new prompts. But I was intrigued and asked how that might go, just out of interest you understand. Then Sapphirescribe suggested that Emmett might be fun for the other half of the pairing. Miss Dare egged me on and then this happened.

I TAKE NO RESPONSIBILITY. TWITTER HOORS MADE ME DO IT!

Thanks to Mamdi for a beta and britpurge (trying out my new word for an anti britpick – what do you think?)

"It's pink." He arches an eyebrow at me as he states the obvious.

"Yep," I grin at him. I rarely get to see Riley looking even remotely uncomfortable, so I like to enjoy the rare moments when they happen. "Rose reckons this is the most likely to fit you, it's a bit on the large side for her – and you wouldn't stand a chance of getting into anything you borrowed from Alice."

"It's lacy." His brows draw together and his lips twist in uncertainty.

I'm still holding the hanger towards him. Riley stares at it, taking in the contents. He's obviously weighing his options. Refuse to wear it and lose the bet, or suck it up and put it on.

"Oh fuck it." He rolls his eyes and takes it out of my hand. "Twenty bucks, and you'd better pay up, Em."

Totally worth it.

I chuckle as I leave his room and head to the kitchen to grab a beer.

I guess some dudes would be uncomfortable having Riley as a roommate, but we get along well and I don't have a problem with his sexuality. He's never been shy about the fact that he likes guys as well as girls. He calls himself pansexual, says he doesn't like to limit his options.

He made it pretty plain early on that he thinks I'm hot, but I told him that it was never gonna happen. I was flattered and all, but I like tits and a pussy. He just shrugged and said he'd figured that was probably the case, but it didn't hurt to put the thought out there.

I'd be lying if I said that he hadn't sowed the seed of an idea. Before he asked me flat out if I was interested, I'd never considered doing anything with another guy. And now? I still don't think it's a road I want to go down but I guess I'm just a little intrigued.

"Emmett," I hear him yelling from his room as I twist the lid off my beer. "Get in here, I need help with these stupid hooks."

I take a swig as I walk back down the hallway and nearly choke as I step through the door of his room.

"How the fuck do chicks manage to put these things on?" He grumbles.

He's half naked, with his back to me. His torso is covered by the pink lacy corset that's obviously causing the trouble. It's hanging off him and he's reaching around trying to do it up and totally failing. My eyes drop lower and stay there. He's wearing matching panties. Pink lace panties. Pink lace panties that cover less than half of his ass cheeks.

Fuck me running.

Riley's ass looks disturbingly hot. It probably helps that he's got that whole androgynous thing going on. Because seriously – from behind he could totally be a girl right now and it's confusing the fuck out of my dick. His body is almost hairless, even the hairs on his legs are pale and hardly visible. He's slender and lean and his legs are long. But his ass... his ass is fucking perfect. High and round and firm.

"Dude," his voice is impatient. I realize I'm practically drooling and feel my cheeks heat in confusion and embarrassment as he looks over his shoulder at me expectantly.

"Uh, yeah... sorry, man." I stumble forward, nearly tripping over my feet as I approach.

The corset fastens with hooks and eyes at the back and he's made a right fucking mess of them in his attempts to do it up. I undo the ones that are wrong and start again at the top. The backs of my fingers brush warm skin. It's so soft. As soft as the skin of any girl I've ever touched. I step closer so I can see what I'm doing better and as I inhale I register that he doesn't smell like a girl at all. He smells clean and kind of nice but definitely all boy. Again with the confusion. My dick settles on half hard, which seems like a reasonable compromise. But the state of my dick is not something I want to examine too closely as my fingers work their way down to the small of Riley's back, getting ever closer to that pretty ass of his. I like girls, I tell myself firmly. Riley is not a girl, he just looks disturbingly like one right now.

I reach the last hook and eye and note that he has two fucking perfect dimples above his ass cheeks. Of course he does. Because I'm not confused enough already and the universe clearly hates me.

"All done," I say and my voice is embarrassingly rough. I clear my throat and step back.

"So how do I look?" Riley grins and turns to face me.

The dark pink satin hugs his torso perfectly. It's a tight fit apart from the empty cups where soft curves should be. His flat, thinly muscled chest rises out of the lacy cups looking incongruous, but his skin is golden and smooth and his slender arms look graceful as he twirls and giggles.

I look down further and burst out laughing. "Fuck, Ri. You'll get arrested if you go out like that!"

The pink lace panties have a panel of sheer satin at the front, but they're clearly designed for women and are completely inadequate when it comes to covering up Riley's junk. One of his balls is half hanging out and the bulge of his dick is clearly visible behind the shiny fabric. Nothing is left to the imagination, I can even make out the shape of the head. I notice at this point that even with this very clear reminder that Riley is a dude and not a chick, my own dick is still rather more interested than I'm comfortable with. I choose to ignore it and focus on the immediate problem instead.

"You're gonna have to put something on over those. " I tear my eyes away and look up at him.

He shrugs. "If you insist, as long as I still win the bet. Let me just get these stockings on and we'll work something out."

Half an hour and a couple of beers later we're ready to roll. Riley is resplendent in the corset, sheer pink stockings and the panties. But the panties are now concealed by some hastily created shorts made from an old pair of jeans, cut as short as we could manage with the kitchen scissors. There's a good eight inches of creamy thigh showing between the tops of the stocking and the denim but his testicles are no longer making regular appearances which is a big relief to me. I'm sure the other party-goers will appreciate that too.

Riley examines his appearance critically in the mirror before we leave. "I wish I had some heels," he frowns. We don't know any girls with size ten feet so he's had to make do with his chucks but at least they're red so they nearly match.

"Come on, Lady Gaga," I roll my eyes at him. "Hurry the fuck up, I need another drink."

XOXOXOX

The party is on campus so we don't have to walk far. Jasper opens the door to us and pisses himself laughing at the sight of Riley.

"That's not really the reaction I was hoping for, Baby," Riley purrs and shimmies up to him running a finger down his cheek.

Jasper backs away, still laughing. "Dude, you look scary."

It's interesting watching the reactions as he wanders about and chats to people. Most of the guys just laugh and look away quickly, keeping their eyes firmly on his face. But I notice that some of the girls' stares linger on him appreciatively.

Riley laps up the attention and I find that I can't look away. I stand by the wall, supposedly talking to Mike and Tyler, but my eyes are following Riley as he moves around the room. My beer is empty already so I go and find another.

I drink steadily, trying to distract myself from the intrusive thoughts that I keep having of ripping that damn corset right off him and... and what? I close my eyes and lean back against the wall, my head buzzing with the alcohol, and I give in to my fantasies. Who am I kidding? The corset needs to stay on. I want to drag Riley back to our apartment, throw him down and fuck that fine ass I was admiring earlier.

"Fuck, Dude," Mike's voice pulls me back to the present. "What are they doing to your roommate now? He's insane."

I look over to see Riley sitting on the sofa with Bella and Alice fluttering around him like butterflies. As I watch, Alice straddles his lap and paints his lips with bright red gloss, while Bella attacks him with eyeliner and brushes mascara onto his eyelashes. Riley pouts and bats his lashes when they're done and the people around them laugh. Then Alice sprays glitter on his short pale brown hair, spiking it up and teasing the bits by his ears into little points. On any other guy it would look totally ridiculous but Riley just looks too fucking pretty for words. He sees me staring and winks at me.

"Jesus," I mutter under my breath and stomp off in search of another beer.

The rest of the evening is like some bizarre form of torture. No matter how hard I try, I can't stop watching Riley. I'm watching him like I'm a predator and he's my prey, and I know it's insane but I can't control it.

He keeps catching my eye and I know that he's aware that I'm watching him. He's totally getting off on it, the little fucker. He returns my gaze with sidelong glances from under his long, dark lashes. Every now and then I catch him adjusting himself in those sinfully short shorts. Of course that immediately reminds me what he's wearing underneath them. I reflect with wry amusement that if he's as turned on by this weird little flirtation that we've got going on as I am, then there can't be much of his junk left inside those damn pink panties. No wonder he's fucking wriggling and adjusting his dick every five minutes.

Someone brings him a drink of something pink with a straw and an umbrella in it. There's a burst of giggling as he toys with the straw suggestively. And this time, when he catches my eye, he holds my gaze and licks his lips deliberately, pornographically. I glare at him and he grins back at me unapologetically.

That's it. I can't fucking take any more. My dick is rock hard and aching and I haven't even dared adjust it in case he notices. I'm pretty sure he's well aware of the effect that he's having on me but I don't want to give him the satisfaction. I stumble toward the stairs and go in search of a bathroom. I need to jack off and I can't fucking wait. But when I reach the top of the stairs my phone buzzes in my pocket. I pull it out. The text is from Riley.

See something you like?

You're a fucking cock tease Biers, I reply, my stupid, big fingers skidding around on the touch screen in my frustration.

The reply comes back immediately. If you need help with your cock, all you have to do is ask.

It feels as if all the blood in my body that wasn't already there, drains away from my vital organs and re-routes directly to my dick. I slump down on the top step, feeling dizzy and slightly panicky. Was I really going to do this?

But I'm already typing the words. Meet me outside in five minutes.

When I close the front door behind me he's waiting at the bottom of the steps. His eyes are dark and unreadable as I face him, my heart pounding in my chest.

"Home?" he gestures with his head.

I nod and we fall into step beside each other. I walk with my hands in my pockets, itching to touch him but unsure and wanting privacy before I chance it. We don't talk, and the tension builds between us until it's unbearable. My chest feels tight and I'm practically hyperventilating. I've never felt this nervous with a girl.

I fumble with the key in the lock, cursing, until he reaches and takes it from me, his fingers brushing mine. He smirks at me as he opens it on the first attempt and holds the door open. I push past him, brushing against him deliberately and turn to watch him as he closes the door behind us.

He advances on me, a hungry gleam in his eyes and grabs me by my belt loops, pulling me into him. He slides his arms sinuously around my neck and presses his face close to mine until I feel his warm breath on my lips. "Are you sure you want this?" He whispers.

I'm incapable of speech so I put my hands on his ribcage, feeling the lift as he breathes and the slippery satin under my palms. The moment stretches out between us. And then I nod my head.

"Thank fuck," he groans and then his lips are on mine and everything is frantic. I taste lip gloss and his tongue as he pushes his way into my mouth, more aggressive than any girl. I feel the lightest scratch of stubble on my chin and it sends a surprising jolt of heat to my cock. He's slim and lithe under my hands, but strong. I push him back against the wall but he gives as good as he gets, grabbing my hips and pulling me hard against him, grinding and moaning into my mouth.

I reach for the button on his ruined jeans and unfasten them, desperate to get my hands on that ass that's been in my fantasies all night. He helps me push them down and toes off his sneakers as he steps out of his pants. My hands slide round to feel his ass, and it doesn't disappoint. It's warm and firm, smooth under my hands and he shivers against me as I squeeze and stroke. My lips are on his neck, tasting and exploring, moving lower to lick along his collarbone and making him gasp and buck his hips into mine.

Feeling bold, I slide my right hand around, slowly tracing a delicate line with my forefinger along the soft skin, just above the lace of his panties. When I reach the soft line of hair that runs down below his navel he bites me hard on the shoulder. I yelp, but I can take a hint. I move my hand lower and meet wet fabric, the satin of the panties soaked with wetness from his cock. He pushes into my hand and I explore the shape of him through the damp material. The head of his dick has escaped and is sticking out above the waistband now. When I run my thumb over the slick tip he whimpers, it's a fucking beautiful sound.

"My turn now," he hisses and pulls me around, so that now I'm the one leaning against the wall. The dim overhead light in the hallway casts sharp shadows on his face, accentuating his cheekbones and the length of his eyelashes. He looks like a girl again but my hand is still on his dick, pumping it and making him gasp. It slips from my grip as he drops to his knees and I lean my head back and close my eyes as I feel him swiftly unbuckle my belt and open my pants, pulling my cock out with deft hands.

When his hot mouth closes around my dick and his tongue flickers over my slit, tasting me, I suppress a sound that would have been frankly embarrassing if it'd escaped. He sets to work then, sucking and licking like he was born to suck cock. The boy is like some fucking genius of head giving, and within what feels like only minutes I'm almost ready to blow.

I pull his head away, chuckling as I notice the glitter in his hair. What a gay cliché. "Riley, stop," I gasp. "I don't want to come yet."

He pulls off with an obscene popping noise; he does this shit on purpose I can tell. "What do you want, Em?" He asks me, looking up through his lashes, his lips wet and shiny with his spit and my pre-cum.

"I want to fuck you," I reply, my voice catching in my throat as my heart pounds faster.

I hold my breath, terrified that he'll say no. But his face breaks into a smile that's fucking beautiful to see, and he stands up and takes my hand. "Come on, I've got condoms and lube in my room." And he pulls me down the hallway before I have time to change my mind.

Luckily Riley seems happy to take charge because I'm freaking out a little again at this point and have no idea what the fuck I'm doing. He bosses me around, tells me to strip for him and watches me while I do it. That shit turns me on. He just lies back on the bed in that fucking pink corset and stockings, and those damned panties that barely cover his cock and balls and he palms himself while he watches me. He even makes me flex for him so he can check out my muscles. He makes an approving noise and moves his hand faster on his dick.

"So," he says, raising his eyebrows. "Do you want me to strip for you? Or does this pink shit stay on?"

"Keep it on." I feel myself blush furiously but the pink shit has to stay. He grins at me and my cock twitches. That just makes his grin get even wider.

"Okay then." He tosses me a condom. "Put this on."

I tear the wrapper and roll the condom swiftly down my length as Riley slicks his fingers with lube and reaches down between his legs. He pushes the panties aside and prepares himself with impressive efficiency. Then he rolls over onto his hands and knees and presents me with that perfect ass. I make a noise that's somewhere between a groan and a whimper as I crawl onto the bed behind him. I'm past caring about the sounds that I make. I run my hands over his ass almost reverently. It's so fucking beautiful it's ridiculous. It makes me wish that I could paint or write poetry or some shit like that because this ass should be immortalized. I shake my head and chuckle at my insane thoughts. Riley turns his head and rolls his eyes at me.

"Any time today would be good," he huffs impatiently.

I smack his ass for that comment, only lightly but it makes him jump and hiss all the same. So I kiss it better, licking the pinks marks left by my fingers. Then I grab the lube and smear it on my cock.

I pull the panties aside and take my first look at another dude's asshole. Wow. I doubt mine's that pretty to look at. Riley's is pink and almost entirely hairless and if it wasn't for the bulge of his balls below it, I'd think it belonged to a chick. Not that I've banged a chick in the ass yet, but I've had a look and thought about it once or twice. Riley's hole is glistening from the lube he's already applied and I reach a tentative finger out to touch. He arches his back and pushes back when he feels the pressure and I watch in amazement as my finger slips inside him. It's tight and hot and feels fucking awesome.

"Fuck, Riley," I mutter.

"That is the general idea," he wiggles his ass impatiently. "Get the fuck on with it would you?"

I let my finger slip out of him and I'm about to line my cock up at his entrance but then I realize something. This way around, he really could be mistaken for a girl and since this is my first time fucking a guy, I want to appreciate it. He might be wearing a corset and pink panties, but Riley is all boy and I want to see him. I want to be able to see his cock while I fuck him.

He senses my hesitation. "What now?" He's actually starting to sound really pissed. This amuses me.

"Get on your back." It's my turn to take control now. "I want to see you while I fuck you."

He moves quickly, his face surprised and flushed. "I didn't think you'd like it this way around," he says. "Straight guys usually prefer doggy."

"Jesus. How many straight guys have you fucked, Riley?" I snort. "Actually, don't answer that now. Shut up and let me fuck you."

And miraculously he does just that. His eyes are intense as I tug those panties aside for the second time and press into him finally, and his breathing hitches. I go slowly, watching to make sure he's okay but he nods in encouragement and pulls at my hips, telling me without words to go deeper. He's so fucking hot and tight that I know I won't be able to last long, but I try my hardest. I move slowly at first, taking my time and trying to control the urge to slam into him hard and fast.

But Riley, as always, has other ideas. He wraps his legs around my waist and urges me on, his hand pulling the lace of his panties down so he can pump his cock as I push into him harder. I push his hand away because I want to touch him. I want to feel him cum in my hand. I curl my fingers around him and find a rhythm in time with my thrusts. I feel the build of tension, unbearable and I can't hold on anymore.

"Fuck… Riley," I gasp as my body bucks into him and I feel my cock twitch and spill into the condom. I keep up the movement of my hand on his cock and he follows me almost immediately, his fingers digging into my biceps and his legs wrap tight around me as he arches and spurts, splattering the pink satin of his corset with cum. It's the hottest fucking thing I've ever seen in my life, hands down.

I collapse over him, panting into his neck. He smells of sex and musky sweat and hot boy.

Fucking hell, I've just fucked my roommate, my very male roommate.

Riley grabs my chin and pulls my head around, interrupting my freak out with a messy kiss and I stop over-thinking things and kiss him back for a while.

Eventually I pull away because I need to breathe, and I chuckle as I look down at the state of him. "Holy shit, Dude. Rose is going to fucking kill you if she finds out you jizzed on her corset."

"Technically it was your hand on my dick when the jizzing occurred," he points out. "So I think you need to accept your share of the blame. If we have to buy her a new set you can pay half." Then he grins wickedly at me. "Actually, you owe me twenty bucks anyway so I reckon you can just pay for all of it."

He looks so fucking pleased with himself that I have to kiss him again just to wipe the smirk off his face. I could get used to this, I reflect as I slip my tongue into his pliant mouth. And if I buy Rose a new set of underwear, then Riley can keep this one… and maybe he'll be up for a repeat performance sometime.

A/N: I hope you liked this latest flight of fancy. There is now a sequel so click on to the next chapter!
