You sighed as you looked down at the paper, crossing the first and third items off the list. The second was going to be a bit harder, unfortunately; your foster brother had a habit of hanging around and cramping your style as much as he could manage. He felt like a real brother in that way… okay, maybe he felt like a real brother in most ways, a consequence of knowing him for most of your life, but he was definitely not your real brother. You remembered that each time you caught yourself staring too long when he was shirtless, or returning from the gym all veiny and glistening with sweat.

But you also remembered that he was still the closest thing to a real brother you'd ever had, and you scolded yourself internally for ever acting differently.

It didn’t matter now— you had Bucky, and he was the most amazing guy you’d ever met.  No, Steve was definitely not happy that introducing his best friend to his sister led to a relationship forming, but he couldn’t stop either of you in spite of his efforts to keep you apart.

Bucky had once expressed his suspicions that it was at least in part due to jealousy, if subliminal.  But you denied it unilaterally— he’s basically my brother, you told him, though it was more of a reminder to yourself than anything.

Perverted concerns about Steve’s motivations aside, Bucky was a great guy.  A bit of a sweet-talker for sure, and not exactly known for his ability to keep a long-term, serious relationship, but he was adamant that you had changed that and for once you were beginning to believe him.  You’d said from the beginning that you didn’t need this to be the proverbial ‘it’ for either of you but that you didn’t do hook-ups— especially with your brother’s friends, and extra especially with your brother’s closest and longest friend.  It only took a brief speech and two shots to convince you, now six months later and you were still going strong.

Days like this made you so happy you’d given in to his advances.  But they also made you regret giving in to Steve’s idea to be roommates in college.

“Stevie!” you yelped as he walked in, stuffing the to-do list into your backpocket.  “Just the man I wanted to see.”

“I doubt that,” he scoffed.  “It’s Valentine’s Day, I bet you want to see Bucky.  He’s coming over, right?  And you want me to fuck off so my best friend can go to town on my sister?”

You frowned, crossing your arms.  “I wanted to see you because I have a gift for you.”

“... you do?”  His eyebrow raised and you hoped your smirk looked just as smug as it felt.

“So do you want your gift or do you want to be an asshole?”

“Do I have to pick just one?” he joked.

“Just come over here,” you instructed, waving him closer.  He seemed hesitant, but eventually did as you’d asked.  From your other back pocket you pulled out two tickets.

“Rangers, center ice,” you beamed.  “For you and a date.”

“And this isn’t just an excuse to get me out of the house?”

“No, it’s a thank you for being such a great brother.”

“So, if I wanted to take Bucky…” he trailed off, already calling your bluff as you rolled your eyes.

“Okay, that’s just sad.  There’s no reason you can’t find a girl to take— god knows Bucky hasn’t spent a Valentine’s Day alone since the fucking eighth grade.  And you’re just as cute as he is!”

“Well, if you could alert the rest of the female population to that, that would be great,” he scoffed, “but until then I’ll take the tickets,” he decided as he took them from your hand.  “A Rangers game might be the only thing distracting enough to keep me from thinking about what you and Buck are gonna do while I’m gone.”

You were hoping for a little more enthusiasm considering how much the tickets had cost you, but at least he was going to go and give you the apartment to yourself for the evening.  “You’re welcome, by the way.”

After stripping and sprinkling rose petals on the comforter, you'd actually found a YouTube tutorial on how to blindfold and handcuff oneself, and it was a little odd that enough people had this problem to merit its existence but it was still very helpful: turns out the secret is to blindfold yourself first but keep it folded up with one eye able to see until you do the handcuffs, then use your arm to slide the blindfold down into place.

It was tricky, and a little bit extra awkward while naked, but you figured it out and smiled proudly to yourself as you completed your last task on your to-do list.

Now, for likely the most difficult task of all: waiting in darkness and silence for Bucky to arrive.

Apparently it is, in fact, possible to be slightly bored yet titillated.  The thought of what Bucky would do to you when he got here was exciting, but it only made you crave his presence more which enhanced your quiet loneliness.  It wasn't like you could read a book or listen to music to kill the time, so you settled for humming to yourself as you waited.

Don't go changing, to try and please me, something something before, hmmm

I just want someone that I can talk to, I want you just the way you are...

But that grew tiresome quickly and you resorted instead to planning exacty how angry you would be if Bucky was late when you were waiting for him in such a compromising and inconvenient state.  For a moment you imagined he'd really gone to the Rangers game with Steve and became briefly livid over a hypothetical situation.

The crackling roar of Bucky's motorcycle outside was distant but undeniable, making you smile in anticipation.  You worried for a moment that you might have locked the top lock of the front door by instinct, but thankfully Bucky and to make it inside alright since next thing you knew, your bedroom door was opening.

The rattle of the doorknob made your breath catch; you opened your legs slowly in time with the quiet creak of the hinges.  “I’ve been waiting for you…” you purred.

“Hi there, babydoll,” Bucky’s voice answered back huskily.

The heavy steps of his boots made it clear he hadn't taken his shoes off at the door, a habit that had driven you crazy since he was your annoying brother's also-annoying best friend.  Was this the real reason he'd chained you up, so he could freely irritate you?  What next, was he gonna put a cold drink on your nightstand without a coaster?

"You really went all out for me, sweetheart," he noticed, his voice closer than you'd expected; it was fun to not know exactly where he would be, it made you squirm under the gaze you couldn't see but could somehow feel.

How weight joining yours on the bed was a good sign to his location though, along with his hands sliding up your legs.

“Look at this pretty pussy,” he cooed pridefully as he dove in suddenly and licked a thick stripe through your folds.

“Fuck,” you shivered, tugging on your handcuffs unintentionally.

“Feel good, babygirl?” he pressed, chuckling when you nodded.  “You want more?”

“Please,” you whimpered.

He didn’t get back to it right away, the weight on the bed shifting slightly, and it made you fear that he planned to make you beg more before eating you out— but finally his lips returned to you as his tongue explored your sex.

“Oh god,” you moaned, your back arching of its own volition.  It was a little different than he normally did this— less confident and measured, more cautious yet hungry.  Typically he teased you a lot more, knowing exactly the spots that drove you wild and intentionally leaving them understimulated until you begged him to let you come, but now as soon as he found them he was targeting them— perhaps a rare show of mercy from the guy who was normally happy to leave you on edge for hours.

You could feel his moans vibrating into you when he slid his tongue inside and against your channel; it instantly made your back arch as the handcuffs quietly clinked above your head.

He stopped just a little too soon, pulling your hips up until the back of your legs were resting on the front of his.  Being manhandled by him turned you on enough to make you bite your lip.

"Fuck, put your cock in me, wanna feel you," you moaned your plea as you heard the rustling of clothes; your mouth watered when you imagined Bucky stripping, with that insane body of his.

His thick head glided over your entrance and you were preparing to beg some more when he suddenly pushed in, giving you what you wanted so much faster than normal.  Not that you were complaining!

He was also much quieter than normal, which you were actually willing to complain about but didn't.

"Oh god," you groaned at the feeling of him stretching you open, gasping when his cock brushed right over your spot— it made your body jolt each time he pulled back and hit it again.

"Feels good, huh?" Bucky asked and you nodded happily.

"So good," you whimpered.

"I wasn't asking you."

Before you could question it, Bucky’s calloused fingers pulled up your blindfold— but it was Steve’s face above you, Steve’s body on top of yours… and, much to your horror, Steve’s cock inside you.

“What the fuck?!” you yelped, trying to squirm away as you tugged at the cuffs but failing completely.

“Fuck,” Steve winced, “you get really tight when you struggle like that.”

“Don’t act so surprised, babygirl,” Bucky cooed playfully as you turned to stare at his devilish grin.  “You wanted this… you just didn’t want to admit it to yourself.  And Stevie here always wanted this, too, and aren’t you so glad he told me?”

You shuddered as Steve continued thrusting, pushing his cock so deep it made you feel a little nauseous.  "Steve, you've gotta stop," you begged.   "If you love me, you'll stop."

"That's the thing: I love you too much to stop."

He moved faster, paying no mind to your confused whimpers, holding your hips tight as his head fell back slightly which brandished his thick neck and bobbing Adam's apple.

"There's no point in pretending," Bucky reminded you coldly, watching the whole thing with crossed arms and an expression that almost looked… bemused?  "You already showed us how much you love it, so don't waste your time acting so disgusted now."

You regretted more than anything saying that it felt good, literally asking him to fuck you before you really understood what you were asking for: you thought it was Bucky, yes, but that didn't mean it was an act.  It did feel good, and that must've been obvious to everyone since you were so wet already.  You could hear it each time he pushed all the way in, that telltale squelching noise that was somehow disgusting and hot all at once.

Steve wasn't so quiet now that he didn't have to be.  "God, you feel so good," he whispered, grabbing the backs of your knees and pushing your legs up.  It forced his cock even deeper and you choked on your own suppressed moan.

You heard Bucky opening his belt, and turned your head to see him pull out and stroke his cock while he watched Steve fuck you.  It was hard to imagine what he was getting out of this; he never seemed like the sharing type, if anything he sometimes became too possessive.  But clearly there was a lot about him and Steve that you didn't understand.

"Play with her tits," Bucky instructed, voice a bit deeper as he pleasured himself, "makes her come so fast."

Steve dropped your legs to rest on his shoulders so his hands were free to grope your chest, thick fingers twisting and tugging your nipples.  Annoyingly, Bucky knew his way around your body well by now, and so it was difficult to pretend that Steve's touches weren't sending shocks of pleasure right down your spine and to your core.

You had been biting on your lip so hard to stay quiet that you feared you would break the skin, until Bucky leaned down and gave you a little slap on the cheek— not very hard, but enough to make you gasp which in turn released the moan you'd been holding back.

"There it is, honey, don't be quiet for my benefit," Bucky encouraged.  "It's okay to like it, I'm not gonna be jealous."

As if that was your concern; angering your boyfriend by enjoying being fucked by your foster brother.  

"You really overestimate my interest in your— fuck— in your feelings," you panted as you glared up at Bucky where he was grinning down at you with a look that almost indicated pride.

"You're gonna come, aren't you?" he asked, ignoring your resistance entirely.  Whatever chance you had at pretending he was wrong was lost when, just for a moment, your eyes widened at his question.  "Yeah, thought so.  I can tell by that dumb look on your face.  I'm close too, babydoll, betcha wanna taste it…"

His free hand roughly held your jaw open as he stroked himself desperately, his weak groan coinciding with the moment you felt his hot seed spray into your open mouth, his taste familiar despite the entirely surreal circumstances.

It was purely coincidence that you came in that moment, your walls bearing down on Steve while you tried to stay silent so you wouldn't choke on Bucky's spend.

"Fuck, that's it, gonna fill this pretty mouth— god yes, you'd better swallow it all," he sighed as come painted your tongue and the inside of your cheek.  Maybe it was more than normal or maybe it was just that he was tightening his hand around the head of his cock to get every drop in your mouth, but either way it was enough to give you quite a mouthful to swallow, which you did without much question due to force of habit.

"M’close too," Steve warned as Bucky stepped back, "I'm gonna come."

“No, Steve, not inside,” you whimpered, hearing the way your voice had weakened after your orgasm, “you can’t…”

“I can,” he disagreed, “Bucky said so.”

Once again, Bucky's will was more important than your own, and your desperate pulling at the handcuffs was only another reminder of the way you'd guided yourself into his trap.

"Don't," you stammered one more time, but it was hard to focus when he was filling you exactly how you needed, when his thick hands gripping your waist felt just as perfect as you'd secretly imagined so many times… 

Denial is a powerful drug, but so is two orgasms in a row.

"Fuck!" you yelped as you felt a gush of warmth drip from your entrance, even further wetness spurring on Steve's fast and brutal thrusts into you.

"Knew you'd love it," Steve mumbled, growling slightly as he slammed into you.  "Knew you'd take it so well, make a pretty mess all over my cock— fuck I can't wait anymore, gotta fill you up, oh my god... gotta give you my load, honey, you want it?"

"Yes," you sobbed, "Steve, yes, come in me…"

He didn't need much more encouragement than that, groaning loudly as you felt his cock flex and pulse against your walls, his release overwhelmingly hot inside you.

You sighed in time with Steve as he finally stilled, and it was hard to know where to look when Steve and Bucky were both staring down at you.  “What happens now?” you found yourself asking, not so much a literal question about the next task but more about what the three of you were going to do with all the unfortunate truths that had come to light in less than half an hour.

“What happens now is I take my turn,” Bucky informed you sternly, pushing Steve aside.  “Did you really think I wasn’t gonna fuck my girlfriend on Valentine’s Day?”
