Summary: Severus becomes the subject of Lily and Remus' debate, and manages to settle and internal debate of his own.

They were in the library together. Severus had tried not to look out for them, tried to ignore the fact that Lily was getting so chummy with her fellow Gryffindor, but when he rounded the Potions shelving and saw them sat at the table, he couldn't help but stop and stare.

He wasn't sure when he had first become aware of Lily's friendship with Lupin. They had never exactly not been friends, both being likeable people and in the same house, but something had changed this term; they had begun to spend enough time together that it no longer felt like they were simply housemates and study partners, but that they were friends... and perhaps something more.

That was what bothered Severus. At least, that was what he wanted to think bothered him about them. It was much easier to equate the roiling in his stomach with simple jealousy than with a more confusing set of emotions and desires, rushing upon him even as he stood there watching. Two heads were bent close together as they shared a book. With the sun behind them, Lily's hair was aflame, and seemed to transmit some of its fire to Lupin's as the light picked out the warmer browns in the shaggy cut brushing his collar.

Looking back abruptly at Lily, Severus drank in how beautiful she was. So pretty and feminine with her full lips, her perfect nose with its sprinkling of freckles, and her large, green eyes. He yearned for a connection with her luminous gaze, which would reassure him that despite school loyalties he had known her first, and she would always belong to him.

Lupin had freckles, too. Just like Lily's, there were enough to be enticing rather than glaring. He didn't have green eyes, though. At least, Severus was pretty sure that Lupin didn't. He hadn't noticed them being green in the past, but then Severus hadn't noticed the auburn highlights in Lupin's hair before. He wished he was closer, so that he could check just what colour Lupin's eyes actually were. So he could see the proof that Lupin was ordinary, and not worth the pounding of his heart in his chest. That belonged to Lily. Lupin couldn't have it as well.

He gradually became aware that Lily and Lupin were looking at him. They were both smiling: Lily with an appealing twist of her ripe lips that made Severus' legs turn to jelly; Lupin with a toothy grin that made the fine hairs stand up all over Severus' body.

In that moment he decided he hated them, and, ignoring Lily's call, he sharply turned and fled from the library; running from the conflicting attractions to Lily's generous curves and the strength flexing in Lupin's forearms.

"Why did you run away like that, Sev?"

"I remembered something."

"You didn't look very happy."

"Do I normally?"

"Good point. Hey, so you want to go over the next Potions assignment in free period?"

"I'm busy."

"Oh. Okay. Well, I'll see you after dinner, then."


Severus closes his eyes as he hugs her, and breathes in the scent of her hair and skin. She smells of the summer: of their summer holidays together; of the clumsy kiss they had shared the night Severus had nicked some of his dad's vodka and topped up the bottle with water. It promises him things, and he lightly trails his hand along the curve of her waist and hip.

She pulls away and smiles at him, and Severus is relieved that he is normal again.

---

"Whoa. Sorry, Severus. Here, let me help you."

"Watch where you're going, Lupin. And get your hands off my stuff!"

"Sorry... So, er, you had a chance to look at the Potions assignment, yet? I was thinking of going to the library after dinner to do some reading. You want to come?"

"Sod off, Lupin. I'm not falling for it."


Severus wrenches the last of his books from Lupin's grip, and tries not to think just how strong Lupin must be to have caught him like that, tries not to remember how Lupin had pulled him tight against his body to save him from tumbling down the stairs.

He strides down the corridor, fighting the urge to run, fighting against the impossibility of Lupin's blue eyes: just as captivating as Lily's green.

---

When Severus meets Lily after dinner, and they end up in the Astronomy tower holding hands and talking about their day, he thinks of Lupin and feels inexplicably guilty; as though he is cheating. Just as he had felt he was cheating on Lily when he had spent free period watching Lupin teach Potter and Black how to play football.

He tells Lily that was what he had been up to, trying to ease the tangling of his conscience.

"Potter's shit at footie. I saw Lupin teaching him and Black how to play."

"You're hardly the next Emlyn Hughes, Sev."

"Wouldn't want to be! Sodding Liverpool... You know, Lupin's not too bad."

Lily squeezes his hand and smiles.

---

The next day, after an evening spent in Lily's company and the kiss they had shared before parting ways, Severus was feeling more settled. He definitely loved Lily, had always loved her. The thing with Lupin had just been because he was annoyed Lily was spending time with the tosser. There was no way that he was interested in Lupin that way.

As he continued further down the aisles, towards the far back of the library, he was relieved to see that the table Lily and Lupin had sat at together the day before was now empty. He headed past it on his way to his favourite section; the neglected one close by the restricted, in which the books the library couldn't quite decide what to do with resided. They were mostly works of philosophy or theology to which the library cataloguing system couldn't firmly assign Muggle or magical status. As a self-conscious half-blood, Severus found them fascinating.

He also relished the solitude these stacks provided, but today it was disturbed. He scowled as he turned a corner only to be confronted by Lily and Lupin, together, again.

They appeared to have been arguing, and they broke off sharply when they caught sight of him. Lupin looked guilty, and Lily looked like she did when she was trying not to feel guilty.

She smiled at him. "'Lo, Sev," she said quietly, adding in a stage whisper to Lupin, "Told you he liked reading this stuff."

Severus narrowed his eyes. "Why are you here?" he asked bitterly. "You could have found a better place to sneak off to if you knew I might turn up."

"Ah, but we wanted you to turn up," Lily teased, and Severus clenched his hands into fists.

"Fuck you! You could have just told me you didn't like me!"

He turned swiftly to go, shaking with his anger, livid at having been strung along and mocked.

Yet, he was prevented from leaving by two pairs of hands. Lily and Lupin grabbed an arm a piece, and they pulled Severus backwards, deeper amongst the shelving.

"Let go!"

"Shut up, Sev!" Lily snapped back at him. She released him, making him stumble into Lupin, who wrapped one of his arms around Severus' chest to keep him still. Lily drew her wand and cast a strong privacy charm around them. "Stop being an idiot," she told him. "We wanted to be caught because we wanted to talk to you about something."

"Oh." Severus stopped struggling, and was uncertain as to whether he was glad when Lupin subsequently released him. "About what?" he asked, consciously trying to keep his tone petulant, but his relief at not being made fun of making it lightly curious.

It was easier to glare when Lily and Lupin only looked at him in reply, and he tilted his chin up in defiance of his natural instinct to hide behind his hair. "About what?" he repeated emphatically.

"We wanted you to settle an argument we've been having," began Lily.

"Lily, I told you I don't –" Lupin tried to interrupt.

"I thought that I had won, but then I thought maybe we'd both lost."

Lily sharply pushed Lupin's arm away when he reached out to silence her and Severus' lips twisted in amusement.

"What was the argument about?" he invited, finding Lupin's obvious discomfort entertaining. Lupin didn't try to touch Lily again, and he didn't say anything in protest, but his face was red.

Lily grinned, her eyes flicking between Lupin and Severus, and Severus' grin widened as he anticipated the embarrassing revelation to come.

"We were arguing about... you being gay."

"What!?"

Lupin made a noise of annoyance. "I told you this was a stupid idea, Lily, I –"

"What the hell made you think I was gay?" Severus demanded, ignoring Lupin's protests. "I'm not!"

Lily nodded. "Yeah, I know you're not, but I don't think you're straight either."

"Lily!"

Severus stared at Lupin, who had shouted at the same time as him. He looked as angry as Severus felt, and it was a startlingly good look on the boy. It made him look older, and frightening, in a confusingly attractive sort of way; it brought back in a rush all the stolen glances, all the confusing flutters in his stomach.

"I'm not gay!" Severus repeated. He couldn't be. He loved Lily. He wouldn't love Lily if he was gay, no matter how he sometimes felt about...

"I know," Lily replied, as though she were talking to a moron. "You wouldn't fancy me if you were gay. You're obviously bisexual."

"Bi-what?"

Lupin frowned at him, and Severus felt the burn of his blush rushing up his neck and into his cheeks.

"Surely you know what a bisexual is, Severus?"

"Of course I fucking know what one is!" Severus yelled. Of course he knew.

"Calm down, Sev. We're only trying to help."

"Help?" Severus stared at Lily in disbelief: she thought that accusing him of being a - a deviant was helping?

She nodded despite his incredulous tone. "Yes, help. Help you discover yourself."

Severus started to shake his head. He knew that look, and if Lily thought that he was going to be another one of her projects, she had another thing coming. He wouldn't let her do this to him. He wouldn't let her turn him into even more than a freak than he already was.

"I don't need any help discovering myself," he informed her icily. "I discover myself quite regularly, thank you very much. Often while thinking of what you looked like in your swimsuit last summer."

He was quite pleased by the furious colour that came into Lily's cheeks, but completely thrown when she launched herself at him, mashing her lips against his own. He stumbled backwards, coming up hard against a stack. Realising that Lily wasn't merely attacking him, but kissing him as well, he started kissing back. He moaned in disappointment when she wrenched herself away.

Blinking his eyes open again, his fuzzy gaze sharpened on Lupin's face, which had appeared over Lily's shoulder, and which was much closer than Severus was comfortable with. Lupin's expression was blank, but his intent was obvious as his face came nearer still. Severus tried to push Lupin away, but Lily quickly grabbed hold of his wrists. He could easily have shaken her free, but he was distracted by Lupin. His eyes widened as Lupin paused the brush of a breath away. The instinct to turn his head away melted under Lupin's gaze, and he began to wonder: what if? What if it was all right to watch Lupin as much as he watched Lily? Couldn't he just...

Their mouths pressed together, the second mouth Severus had ever kissed, and the last of Severus' denial melted under the warmth of Lupin's lips. They were thinner than Lily's, and rougher, and even more demanding, despite the fact Lily had been fierce with him before. It was neither better nor worse: just different, and new, and exciting, and no where near as wrong as he had feared.

He tried to chase after the kiss when Lupin slowly pulled away, but the spell was cruelly broken as Lily's smug voice confirmed, "Definitely bisexual."

"Actually, I think I'd rather be gay," he snapped at her.

He was surprised, but not displeased, when Lily's retaliation took the form of another kiss. She released his wrists, and he slipped his arms about her. Wanting to take control of the situation, he began walking her backwards until she was now backed against some shelving. She didn't resist at all, only sighed and licked at his lips, taunting him into deepening the kiss and sliding his tongue against hers.

He started at the unexpected touch on his hip. Lily's hands were on his shoulder and in his hair, and he broke the kiss to look sideways at Lupin. Lupin gave him an enquiring look, and Severus found himself nodding without quite knowing why.

He had assumed Lupin would kiss him again, but instead, one of Lupin's hands gently took hold of Severus' chin and turned his face back towards Lily. He felt Lupin's warm breath against his ear, before hearing, "She can have your lips, if I can have your cock."

Severus' eyes went round at hearing Lupin say the word cock, and then squeezed shut when a confident hand cupped the front of his trousers. He couldn't believe that he was letting Lupin touch him, nor that Lupin seemed so sure of him, nor that Lupin was gay! Despite disbelief, he whimpered against Lily's lips and rubbed his groin against Lupin's hand. The thread of his thoughts broke, and any protest he might have had quickly disappeared as Lily grabbed one of his hands and pulled it to her breast at the exact same time as Lupin's teeth latched onto his neck.

"I think he might be convinced," he heard Lupin mutter gruffly between bites, and Lily laughed into their kiss. Severus couldn't have cared less.

Lupin had continued to palm his cock as he had worried the skin of his neck. Severus was rock hard, and moaned loudly in relief when one of them undid the clasp of his trousers. A hand pushed on his hip, urging him to turn slightly to the side. He obeyed, not worried as long as he could still kiss and grope at Lily. Lupin had stopped licking at his neck, which was disappointing until he felt Lupin's breath against his pants. Hips jerking in reaction, he broke away from Lily and stared down at Lupin who was proceeding to pull his pants out of the way.

"Severus?" Lily's soft call drew his attention away. She had moved to stand behind Lupin's kneeling form. "Watch me."

Severus' gaze flicked rapidly between Lupin and Lily. He wasn't certain if he really wanted to go this far and he put his hands on Lupin's shoulders, prepared to push the boy away. He was distracted from his purpose by Lily pulling off her jumper, and undoing the buttons of her shirt. Then Lupin's hand closed around his cock, and there was the rasp of a tongue against its tip. Clutching Lupin's shoulders for support, Severus stared at him and then back at Lily as she shrugged out of her shirt, revealing the Gryffindor-red bra beneath.

He was unable to keep watching Lily as Lupin's lips slid down his shaft. One of his hands moved to the back of Lupin's head, fingers spearing through brown hair as he tried to encourage Lupin to take him deeper. He had never fantasised about Lily doing this to him, feeling that she was above something so dirty, but Lupin was a boy, which made it even weirder, but somehow more acceptable to him. Christ! More than acceptable!

His eyes flew open again at a touch against his face. Lily smiled at him. She was wearing only her bra and knickers, and Severus groaned loudly.

The groan became a sound of disappointment as Lupin suddenly stopped sucking on him, and stood up. He stared at Lupin's swollen lips.

"So, do you agree that you're bisexual?" Lily asked him.

He couldn't find his voice. Instead he nodded, and darted his head forward to kiss Lupin, swiping his tongue along the lips that had been around his cock. He thought he could taste himself. Lupin kissed him back fiercely and he felt a hand, Lily's this time, wrapping about his cock.

"You can have us both," Lily was saying as she pumped at him. "We both want you. It's why we were arguing."

Severus wrenched his mouth free. "Shut up! I get it, already. I fancy both of you. I want both of you."

"Right answer," Remus growled, and Severus was spun about so that he was now sandwiched between them both, Lily in front and Remus behind.

His cock rubbed against the lace of Lily's red knickers. Before he could move, Lily and Remus had taken over, tugging off his jumper. Remus reached around and began undoing the top buttons of his shirt while Lily started from the bottom. His shirt disappeared in the direction of his jumper, and as Remus stepped away for a moment, Lily stripped off her bra and pressed her breasts against his bare chest. The skin contact made both of them moan, and their tongues tangled again as Severus shoved his hands down the back of Lily's knickers to squeeze her arse.

His hips twitched forward when two hands squeezed his own arse, before tugging his loosened trousers down. He followed example, and pushed at Lily's knickers. In moments, they were all three naked, Remus' chest and cock pressing against Severus' back and arse; Lily's breasts and groin pressing against Severus' chest and cock.

In that moment he decided he loved them. He had no idea why they would both want somebody as ugly as he was, but as they slid to their knees, a mouth sucking either side of Severus' neck, he felt too amazing to examine it further. It just was, and Remus was pushing him forward over Lily.

His cock was nestled between Lily's thighs and he caught her gaze, asking permission for something he had imagined time and time again, wanking behind the curtains of his Hogwarts four-poster. Her eyes held his as her hand reached down between them, guiding him. He heard Remus cast the spell that they had forgotten, and then he was sliding inside her for the first time. His eyes widened as sensation swallowed him, but he couldn't close his eyes or look away as Lily's eyelids fluttered. They finally closed, and her lips bowed before whispering, "Move."

Severus wasn't sure he could, he shook as he withdrew slightly and then thrust forward again. "Good," Lily encouraged.

"Remus?" Severus said shakily, immediately feeling the loss of Remus' warmth when the other boy moved away.

"You really want us both?" Remus asked him, his lips near Severus' ear, his chest once more pressed against Severus' back.

Severus nodded.

"Really?" Remus pursued, and Severus' hips jerked when a finger brushed along his cleft. It made his buttocks squeeze together and a strange thrill buzzed through him, making him harder, making him feel Lily more intensely.

"Y-yes!"

His body vetoed his mind's concerns. He wanted Remus inside him, while he was inside Lily, and didn't care about the logistics. Lily coaxed him into a kiss, distracting him while Remus cast another spell that sent a shiver through him, leaving him feeling loose and wet. He felt open, and vulnerable, but suddenly so right when Remus touched a finger against his arsehole. He pushed back against the finger, and then thrust forward again when a movement from Lily drew his attention back to her. The finger pushed again, and the process repeated itself. He was torn between the two of them, jerking and twitching from wanting them both so badly, wanting it all.

Finally, Remus stopped teasing him with his fingers. He whimpered in relief as Remus' body curled around him. One of Remus' hands was planted just above Lily's shoulder, bracing him. The other curled around Severus' torso, hand splaying low on his abdomen, holding him still for the push of Remus' cock inside him. It stretched; it burnt, but was muted by the warmth spreading from Remus' hand into his abdomen, and from his cock to his balls as Lily squeezed around him.

"I'm going to move now," Remus warned him.

He nodded jerkily to show he was ready. He leaned into the slim hands framing his face, holding him as Remus thrust for the first time. He let out a choked noise that was neither pained nor pleasured. He felt overwhelmed by the sensation inside and outside of him. He was barely aware of Lily's stroking the hair from his face as Remus rocked his hips.

Then all of a sudden Remus hit something inside of him that made lights flash behind his eyelids. He cried out and tried to move so that it happened again. His movements drew a gasp from Lily and she tensed around him. Gradually they settled into a rhythm, Severus moving between Lily and Remus, the air growing heavy with their gasps and panting.

Lily was writhing beneath him, moaning as she strove towards her completion. Suddenly remembering something he had read about, he reached a shaking hand between them, fingers brushing over Remus' hand before dipping lower, feeling for the nub that was supposed to drive girls crazy.

His touch was magical, Lily let out a shrill cry and she convulsed beneath him, making him buck his hips in response. Remus groaned loudly and slammed into him. The force transferred itself through Severus to Lily and she clutched at Severus as she tensed up completely. Severus felt her pulse around him, and that combine with another rough thrust from Remus sent him over the edge. Remus arms were as tight as Lily's about him, flesh crushing him, drying the air and his senses from him. He yelled as he came harder than he'd ever come before.

There was stillness, sudden and satiating, then a small note of complaint from Lily. Severus was boneless, and was glad when Remus pulled him to the side, withdrawing both their weights from Lily's slim body. He sprawled on the floor of the library, unable to process what they had just done.

He was blinking up at the ceiling when two faces came into his view. They were both smiling at him.

"Definitely bisexual," Lily said, a little breathily.

"Maybe," Severus demurred, with a smirk.

He stretched out, and his smile widened when he felt bodies curling up either side of him. He was relieved that the torn feeling was gone. He was a Slytherin, after all. There was no real reason why he couldn't have the best of both worlds.
