It took Hiccup a little longer than Astrid expected for him to come up and join her. Brushing her hair free of its braid, Astrid turned when Hiccup entered the room but didn't really move in closer.

"Everything alright Hiccup?"

"I uh... I don't know."

Placing her brush down, Astrid turned around, seeing the look on his face properly. Confused, dazed, unsettled. Worried.

"What's wrong?"

He frowned, but when Astrid patted the bed he came over, sat down stiffly. There was no actual answer for a minute, instead Hiccup simply stared at her face for a minute, taking in her features and the way he did so told Astrid that whatever was going on, it was probably to do with Lillian.

"I... she... we kissed."

"You and Lils?" he nodded "and... that's bad?"

Hiccup cocked his head, considering her.

"It doesn't bother you?"

"Well, it doesn't bother Lils that we still fuck, so what do you think?"

Actually, it did sort of bother Astrid, but not for the reason Hiccup probably thought. She wasn't jealous. Hel, she'd actively encourage Lils to drag the scrawny dork to bed if she thought her sister would listen. But if Hiccup and Lils were moving forward at their awkward, mutual-pining and seemingly oblivious to how much they liked each other pace, then her own thing with Hiccup probably had an end date being etched on it.

Still, Hiccup needed a friend right now. And Astrid wanted details.

"It's just... I think she regretted it. And so I feel bad. Did I push her?"

"Well, did she hit you?"

"No?"

"Then no, you didn't push her. What did she say?"

Hiccup hesitated for a few seconds, and Astrid was fairly certain he was weighing up breaking Lillian's confidence against the solid likelihood Astrid would find out anyway, since the twins told each other everything.

"Just that I should go, and that you were waiting for me."

They were ridiculous. Honestly, Astrid figured she should just try knocking their heads together. It might make them see sense. Gods, if Lillian had only met him first...

"Just that?"

"Yeah. I tried to talk to her, but she told me to go anyway."

"Then she wants her space. Leave her be for now."

Tangled up as much as the three were in whatever weirdness was budding between them in a mixture of ways, even Astrid wasn't going to try and get physical with Hiccup while his mind was clearly on Lillian. So instead she pulled him down under the covers and settled on him in an octopus-like cuddle, which he seemed to appreciate greatly.

"Night Astrid."

"Night Hiccup."

He hadn't only been cultivating friendship with Lillian; he'd become a friend of Astrid's too. They didn't have the same common interests as the geek-pair did, but Hiccup was engaging whenever he spoke, and they spent as much time together talking as they did in bed. Hel, maybe more. So comforting him when he was all confused was the sort of thing a friend did, and the way Hiccup wrapped his arms around her, clutching Astrid to his chest as he did... it was more intimate than if he was inside her, because she knew Hiccup was emotionally vulnerable and still he felt safe enough to be so, with her.

Hiccup's mouth caught on hers, the taste of menthol Astrid knew wasn't his cold on her lips as she kissed him back. It was slow and soft, almost like Hiccup needed to know Astrid didn't hate him and sought her reassurance. Only when she gave it did Hiccup settle again, still with his arms tight around her. They'd been cuddlers since the first night, never questioned, but Astrid still liked the way he felt around her.

Lillian had an early class, while neither Hiccup or Astrid needed to go anywhere until midday. Still, Hiccup got up early so he could make breakfast for both of them, and how Lillian resisted the urge to kiss him with pancake batter on his face, Astrid would never know. Not that Hiccup and Lillian really looked at each other much, averting eyes like they were in trouble. Or more likely, denial. Stalking her sister to her room, Astrid stood in front of Lillian's door, trapping them both in there for the moment.

"Whats going on Lils?"

"I'm trying to get dressed?"

"Not what I meant. He told me you kissed him so why are you acting all weird?"

Her sister huffed, hunting through a pile of folded fabric for the t-shirt she wanted to put on.

"I'm not. I just... you know what, I don't have time for a trip into my own psyche right now, I have class. Can we talk about this later?"

"Sure, but we are actually going to talk about it. I will tie you down."

Rolling her eyes, Lillian shrugged on a hoody and picked up her bag.

"We will. But I need to go to class."

As if to compound that she wasn't actually trying to avoid Astrid, Lillian hugged her goodbye, pressed a kiss to her cheek before demanding Astrid get out of her way. Feeling relieved that Lils was very much still herself, Astrid let her go, following her down to where Hiccup painted the picture of domesticity, cleaning the kitchen while the sisters talked.

"Is Lillian alright?"

"Yep. She just refuses to be late for class. I'll talk to her later."

Hiccup had his thinking face on the entire time he was doing the washing up, drying his hands on a tea towel Astrid tossed to him before leaning against the side. They hadn't done anything the night before, but they had only seen each other a couple of days ago and Hiccup still bore a few bruises on his chest and collarbone, fading red lines healing on his back.

"What's on your mind?"

"I just hope Lillian doesn't hate me now. Not that I want you to hate me either. But you're still talking to me."

"She doesn't hate you, you mutton head. Like I said, she needs her space."

It was kind of weird; Hiccup was looking to Astrid, his regular friend-with-benefits, for answers on his pining crush on her twin sister. And Astrid, who cared about him a lot, and who prioritised her sisters safety and happiness over all else, was trying to work out how to reassure him without guaranteeing anything that would then put undue pressure on Lillian.

"So... what do you wanna do with the morning?"

Hiccup left a couple of hours later, after a really lazy morning of cheesy TV watching and little else. They didn't talk about Lillian, or much of anything really. It was quiet save for laughter, but comfortable, some fairly good proof they could be around each other and get along without exchanging bodily fluids.

It would probably serve Astrid well to remember it when Hiccup inevitably ended up dating her sister properly. Speaking of which... Lillian would be home soon.

It was getting ridiculous.

Lillian had been sat near his house for the better part of twenty minutes, wholly intended to go in and... she didn't even know. But lurking near Hiccup's place only made her feel like a massive stalker, and Astrid's words about going there and figuring things out as they went were ringing in her head. It wasn't like her. Lillian liked to make decisions based on solid facts and information. All she had was the burn of Hiccup's kiss still imprinted on her mind, and that churning feeling in her belly that urged her on, told Lillian to march in there and... and...

"Hi."

His front door opened to reveal a slightly surprised Hiccup. Maybe she ought to have called first. Or texted. Not just... appeared at his door all jumpy.

"Hey."

"You uh, wanna come in?"

He stepped aside to let her pass, Lillian acutely aware every time she stepped through that front door that the wooden rectangle had borne the very start of all the madness they were entangled in; had Astrid not picked Hiccup up for a hookup that night, then odds were Hiccup would never have sat at her table in the coffee shop, and therefore never have met Lillian.

"I wanted to apologise. I shouldn't have kissed you and-mmph!"

His next words were muffled against her hand as Lillian sought to silence him.

"Shut up."

If she didn't do this now, surging with adrenaline and her sisters blessing, Lillian doubted she'd have the nerve again anytime soon and she needed this... clarity. Hiccup didn't protest, surrendering to her drawing him down, tasting something sweet on his mouth as they kissed. Last night had been an accident, a surprise, a lightning jolt through her heart and Lillian couldn't hope to have processed it all at once. But now? Her mind and body agreed wholeheartedly that this was intentional.

Hiccup was more hesitant, tentative than she expected; she'd seen he and Astrid kissing, and there was more demanding heat there than there was now, but she realised quickly. He was learning her, finding the differences, not falling back on what Astrid liked and figuring it was close enough when they were so alike in many other ways. Burying her fingers in his hair again, she held him in place and kissed that stupidly tempting mouth until she was dizzy. Hiccup's ragged breaths fanned over her face, sweet and fruity to match the taste she'd found on his tongue, his forehead resting against hers.

"Wow. Ok. Wasn't expecting that."

Unsure how to respond other than to continue trying to breathe, Lillian kissed him again. Hiccup groaned against her mouth, the sound winding down through her like warm honey to settle low in her stomach, shuddering as his hands slid around her back and pulled Lillian tighter to him, emboldened by the repeated kisses.

"I like you, ok? A lot more than I meant to. Why do you have to be so bloody dorky and adorable and amazing?"

Seeming a little dazed, Hiccup took a minute seemingly to even notice she was talking, let alone to process what she actually said. The words had sort of rushed out of her. For all Lillian knew, they'd come out garbled and senseless.

"I like you too. A lot."

"As me? Or as Astrid?"

"What?"

His fingers, previously stroking lazily over the dip of her spine, stilled. Lillian steeled her nerve; she needed to know.

"Am I just... close enough to Astrid? Or do you actually like me for me?"

"You. Gods, for you. You're smart and funny and you have the cutest concentration face when you're working, and I love that even though you're quiet you are never afraid to speak your mind."

He was babbling. Lillian reckoned he'd probably continue if she let him, but body overrode mind to push her forward again, satisfied Hiccup liked Lillian as an individual person, not simply as the lookalike of his current partner.

They didn't talk about that part. It wasn't the right time.

Hiccup didn't try to move them anywhere, seeming happy to kiss her in his hallway with no further motive, letting her indicate if there was... more to come. Forcing herself away from his mouth, Lillian looked up into deep green eyes, arousal dilating his pupils and reddening his cheeks.

"Where's your bedroom?"

She'd never been in there. Astrid could probably find her way there blindfolded by now. But it was her first time there, and Hiccup guided her along the route slowly, distracted by kisses and breathless smiles before she finally found herself at the door between them and his bed.

"Hey" Hiccup nudged her cheek with his nose, made her look up at him again "we don't have to do anything. I won't rush you."

Lillian genuinely believed him, and that was enough for her to answer.

"I do, but... go slow? I haven't... in a while."

Hiccup kissed her soundly, sweetly, fingers cradling her jaw tenderly.

"If you want to stop, you can tell me alright?"

It made sense that they go slowly, letting the heat simmer under skin as they laid across his bed, fully dressed and mouths moving. They didn't have that same frantic desire that Hiccup and Astrid had, instead it was a slow burn, building for weeks by then and Lillian wanted to bask in the warmth of it all, not let the blaze climb too much that it couldn't be sustained, that their first time together be a burn out.

Was it ridiculous of her to feel shy when Hiccup ghosted fingers along the hem of her top? Probably. Hiccup noticed her hesitation, backing off and moving his fingers back up to her neck, stroking tingling touches down over her throat, smiling against her mouth when Lillian squirmed. She pushed him back, reaching down herself and tugging up the fabric, watching the awe and attraction written plain as day on his face as her mostly-bare torso was revealed. For a minute, she wished she'd raided Astrid's underwear drawer for something a little more... flattering? But then, that wouldn't be her he was getting. It would be Lillian trying to be more like Astrid.

"Have I told you before how beautiful you are?"

Why did that make her so giddy? Lillian felt herself come over silly, hiding it in amongst fresh kisses and reaching for the t-shirt he had on. Hiccup wriggled until he could help her remove it, skin hot under her hands, unable to help but look at his freckled skin up close for once. The bruises gave her pause, but Hiccup ducked his head to catch her mouth again, distracting her and pulling her close so their warm, bare skin could meet.

His hands slid over the outside of her jean-clad thighs, but there was no ulterior motive in his touch beyond nesting himself there, leaning over Lillian now, letting him rest his weight on one arm, leaving the other free to roam her skin. She could feel him, body shaking slightly in a mix of nerves and anticipation. Hiccup's eyes followed his hand, seeing which spots came up ticklish, which made her shiver in pleasure, finding that little tingly place on her side that brought goosebumps up across her skin.

The flexing motion of his wiry shoulders drew Lillian's hands to him in turn, tracing over his upper arms first, muscles more solid than she'd expected for his slim size. Hiccup's eyes found hers when Lillian's fingers found the marks on his back, still healing.

Was he hoping she'd be rougher? Did Lillian have to match up to Astrid to satisfy him? Him liking it rough and hot and heavy was not really up for debate; else why would he have continued going back to her? Lillian liked that sometimes, but not all the time, and it certainly wasn't the mood she was in now. Hiccup, still watching her face, seemed to sense some internal debate going on.

"You don't have to be anything other than yourself. I only want you to do what comes naturally, what feels right. Ok?"

His words relaxed her, left Lillian more open to his touch as Hiccup rested back on his knees, surveying her with only the tips of his fingers rubbing the outside of her thighs, the touch barely there and completely frustrating. Finally, they splayed over her hips.

"May I?"

Gods, he asked. Heart kicking in her chest, Lillian nodded, lifting her hips to help him remove her jeans. It was only then they realised neither had taken off their shoes, but Hiccup quickly tugged those off her feet with a laugh before her jeans were gone too. His bottoms felt a little scratchy and rough against her sensitive inner thighs, but Hiccup's mouth on her neck was electric and her world seemed to dissolve to just that point for a moment, gripping tight at his forearm until Hiccup moved back to her mouth, stopping first to pepper ticklish kisses on her jaw.

Her bra soon melted under his hands, leaving her heaving chest bare as she quivered under his gaze, big hand closing over her breast and palming her gently. Lillian gasped, unfairly sensitive there and the rough, work-worn skin of his hands didn't help matters, rasping lightly over soft and pliant.

"You like that?"

Lillian could only nod, biting her lip to try not to make some kind of embarrassing noise. Hiccup's free hand came up, thumb working her lower lip free of her teeth, soothing over the indentation of her bite.

"I want to hear you."

His fingers scraped over her nipple, dragging a hungry sound from her throat and green eyes lit up in response, repeating the motion and being very rudely in the way as Lillian squirmed, unable to squeeze her thighs together with him still knelt between them. Her hand flexed against his bicep, having landed there at some point while she was distracted by those lancing darts of heat. Hiccup kept going, touching her again and again, the briefest, cruellest respite found in him letting go only to replace his hands with his mouth. Soft and warm and wet, his lips closed over her nipple and sucked, the sudden jarring pleasure enough to make Lillian shout, shaking under his hungry demands for her pleasure.

Her fingers twisted in the sheets beneath her, panting harshly between those pathetic, desperate mewls and moans. Rather than be put off by her uncommonly wanton behaviour, Hiccup seemed to revel in taking her to pieces, watching her tremble with those intense green eyes of his.

"Would you mind if I took these off? Only I am dying to taste you properly."

Really, it was unfair that here Hiccup was less awkward, the dorky dragon geek clearly some kind of comfortable when it came to talking about sex. And his words did things to her, the vision of him doing exactly what he said enough to make Lillian wetter, her underwear already ruined before Hiccup slid them down her legs and tossed the sodden cotton over his shoulder, crawling up along the bed until he was laid mostly flat on his belly, pressing tender kisses to her slick inner thigh.

The first swipe of his hot tongue was almost too much, so sensitive she was to him already, tightly wound by his attentions to what felt like every other inch of her so far and finding her fingers clutching his head as her hips bucked up. Apparently not quite close enough, Hiccup slid his hands under her thighs, hiking her legs over his shoulders and wrapping his arms around her hips to physically haul her ever closer. There was no escape, no repreive, his unforgiving tongue darting and stroking and tasting and Lillian doubted the beast would be calmed by anything less than her coming completely undone for him.

He wouldn't wait long.

One hand left her hip, worming into the minute space between his mouth and her body so a finger could slip inside her with ease. The second took a little work, her muscles tightening with the promise of an explosive climax. Gods, she'd never known any man so eager, so ravenous to have her tumble to ecstacy in great, crashing waves. It was impossible to deny the building tides, the thrusting of his fingers against the sensitive spots within an obscenely perfect companion to his tongue until both came together to break her completely.

Overwhelmed was a gentle word for what Lillian felt, body shuddering with aftershocks that zipped along her nerves, limbs jelly-like and useless as she fought for control of her racing heart and ragged breathing.

"So... was that ok?"

For a minute, Lillian could only look at him incredulously, as though the twisting of her body and pleading of her voice could have been misconstrued.

"More than."

Hiccup beamed, wiping his mouth on his discarded t-shirt before letting Lillian drag him back up the bed, kissing him and trying to pour all the unexplainable feelings and gratiude for the whole mind-bending orgasm thing into it. Damn. Now she could see why Astrid was never quiet when Hiccup was over.

"If you're tired or too sensitive, we can stop. It's alright."

Lillian shook her head, determined not to leave his house until she'd experienced him fully.

"Just... be gentle?"

Hiccup nodded, drawing her back into a kiss.

"Of course."

They were all but silent as Hiccup's jeans and boxers came off, leaving him naked as she and twitching, sensitive to even the slightest brush of her fingers over his swollen cock. Lillian rubbed her hand in slow strokes, pumping him and feeling the way he pulsed in her hand, straining toward her as Hiccup whined and whimpered, fists rigid at his side as he fought not to insist Lillian go further than the slow exploration.

She wanted to return the favour, but doubted she could really match the shattering bliss Hiccup had given her. Nor did Lillian think he was going to last terribly long, and she'd not have much chance to draw it out. Which was the fun part, really.

He pulled out a condom, letting her take it from his hand and gasping lightly as she rolled the latex down his shaft. Hands slid up her back, tumbling Lillian gently back to the bed, looking up as Hiccup laid between her spread legs, the length of him slipping against her wetness and watching as she quaked with the pressure on such sensitive skin. She could see Hiccup considering pulling away, saying they could wait and disagreed with her body, sliding her legs up to hook around his waist.

"Slow."

He nodded.

"Slow."

Even slow, it was intense, almost too much as Hiccup inched inside her, letting Lillian clutch at his upper back for an anchor until his hips came flush to hers. Letting out a breath she'd not realised she was holding, Lillian felt his forehead rest against hers, heard shuddering breaths drag in and out of his lungs. The tension of muscles in his back told her he was struggling to reign in the urge to just thrust until he came, to go slow as she'd asked.

Finally, his hips flexed, the motion so short it couldn't be called a thrust but it was enough, enough to make him whine with the feel of her wet heat on his pulsing cock and make her shiver, feeling him press deeper inside her. Her body was out of practice, still remembering how to move but Hiccup was endlessly patient despite his own pressing need, thrusting with measured slowness and stilling if she tensed, pecking kisses on her face to soothe her until Lillian leant up to catch his mouth with her own.

How was someone she knew could be rough - Astrid spared no details - so sweet and tender with her?

Uncomfortable craning her neck like that, Lillian rolled them onto their sides, his thrusts a little more shallow as she wrapped her leg over his hip but the height adjustment he needed meant they were eye-to-eye and oh, that was much better.

Not content to have left her a writhing, melted wreck only once, Hiccup's hand left her waist, slid down to press against her clit and she caught his smirk as she moaned before her eyes fell closed, unable to keep them open against the steady onslaught of his thrusts and touch and kisses and just that it was him. The damned gorgeous nerd who'd slipped into her life by mistake, crept under her skin. All the denial in the world couldn't help her now, not with Hiccup pushing her higher, higher, higher...

His guttural, cursing noises as she came were those of relief as much as rapture, holding out for her and barely lasting a dozen more thrusts before Hiccup was bucking and jerking against her, both of them grabbing blindly at the other, holding tight as the feelings surged, grip only loosening as the torrid rush subsided, ebbing away to leave them limp and panting.

Gods, nobody had made Lillian feel like that since...

No. She couldn't think like that right now.

Hiccup rolled over to dispose of his used condom, but he was back within holding range seconds later, wrapping her in his arms and running fingers along her sweaty face, brushing her hair aside lazily. They stayed like that, just coming down from the high, his heartbeat slowing gradually beneath her ear. Finally feeling her nerves settle slightly, able to tolerate touch again, Lillian sat up and tossed her bedmate a smile.

"I have it on excellent authority that you're generally good for more than one round."

Hiccup chuckled, fingers absently brushing a healing bitemark on his chest as though agreeing with her.

"Really? Can't imagine where you heard that."

-HTTYD-

Well, at least now Lillian got laid too!
