So, a little prequel to Confusion here! Takes place a couple of years before Confusion starts. If you're new and missed the warnings, there be Lilstrid incest.

Turning off the oven, Lillian smiled to herself as she laid the tray out to cool. Cooking for Astrid was one of her favourite things to do, because food made her sister so very happy. And there was nothing Lillian loved more than to make Astrid happy.

She glanced up at the clock, giddy with the knowledge her twin would be home in the next half an hour. Most of that time was passed easily enough by cleaning up the ktichen post-cooking, and the last five or so minutes putting the fixings of Astrid's protein shake out ready before Lillian laid across the sofa where she could happily watch the door, waiting.

Lillian was up on her feet before Astrid's key finished turning in the door, and Astrid had barely managed to smile at her before her mouth was otherwise occupied.

"Mmm... missed you too!"

Astrid giggled as she finally closed the door behind her properly. Lillian grinned in return.

"I made dinner... but it's fine to wait if you're not hungry."

She saw Astrid immediately understand the insinuation, helped along by Lillian's hands running up and down over her hips.

"I'm all sweaty."

"When has that ever stopped me? You're only gonna get sweaty again."

Eyes sparkling, Astrid conceded her point.

"True."

Lillian squealed slightly as Astrid lowered herself just enough to hike her sister over her shoulder, paying no mind to Lillian's squirming until they were in range of their bed - officially Astrid's bed, but they always shared - and then Lillian was dumped on it. She bounced a bit awkwardly and had to be mindful not to fall off, but then Astrid was helpfully climbing on top of her to prevent Lillian going anywhere.

Astrid was still in her workout gear from running home, which was a pain to try and take off so she got up (and Lillian pouted) to take it off and run a couple of wipes over herself. The feel of cool wipes on her skin made Astrid moan a little, which might have been exaggerated just to make Lillian a little dizzy with want.

It worked.

Tight shorts joined the sports top on the floor, leaving Astrid in only her briefs that were soon discarded too. The feel of powerful muscles under damp skin thrilled Lillian as she ran her hands down her twins back, enjoying the little differences on Astrid just as much as she loved the familiarity of her sisters body, that sameness unique to identical twins. Astrid nuzzled her neck, kissed the hollow of her collarbone and smirked against her skin when Lillian shivered and mewled, still fully dressed under a wholly naked Astrid.

Astrid set about changing that quickly, sucking red marks along the top of her chest as the buttons of her shirt came loose, very fond of leaving treasured little reminders all over Lillian's body. Lillian often returned the favour, bruises left by her teeth littering Astrid's body from neck to thigh.

When they could never say a word to anybody about the way they loved each other, it was nice to be able to see the marks and know it didn't matter, because they would always have that waiting at home for them.

"Take down your hair for me?"

"Only if you do yours."

They'd often do it for each other, but when eager hands itched to explore bare skin, it was quicker to undo their own hair. Lillian happily buried her fingers in Astrid's messy locks, uncaring that there was a lingering dampness of sweat there still, arousal burning hotter when Astrid breathed "Lils" against her lips. Nobody else called her that. Not friends, not family, nobody but Astrid. That little nickname was theirs, and she hated the sound of it on any tongue but her sisters.

Lips found her breast as fingers brushed her inner thigh, legs parting willingly for Astrid to kneel between. Her body responded so much more intensely to Astrid than anyone else she'd dated - a mutual agreement between the two that it was good for them to at least try that, but nothing serious ever came of it - and even the spots where Astrid's hair brushed against her chest made Lillian tingle. A thumb pressing in firm circles over her clit as a hot mouth sucked her nipple was enough to have Lillian writhing and moaning, hands fisting in Astrid's hair again.

"You're so hot Lils, how do I let you out of the house?"

Her only answer was a breathless giggle, but Astrid didn't seem to need more before she was moving, mouth back on her sisters and the strong, tight muscle of Astrid's thigh pressed against Lillian in ways that made her whimper. She moved her own leg until she could feel Astrid's slick wetness there, letting herself be lost to that blurry, blistering heat, grinding and pushing, nails digging in to soft skin as Astrid panted against her jaw and groped her with abandon. Lillian felt the warmth spread through her, urged along by the spike of pain when Astrid bit down on her shoulder, felt her thighs clamp tight around Astrid's as her sister stiffened in turn.

"You're always the best for 'welcome home' Lils."

Astrid eventually murmured, smiling when Lillian giggled at her.

"You're welcome."

They both needed showers, but Astrid was being too cute as she mellowed post-climax, nuzzling in to Lillian's hold with a sweet little yawn. Sometimes after a long day at work, Astrid needed a nap, and Lillian was happy to oblige as her sisters pillow. They pulled a loose cover up over them so there'd be no shivers from cooling sweat on bare skin, and it took only a minute or two of petting her hair softly before Astrid was fast asleep in her arms. Lillian didn't feel especially tired, but she was warm and comfortable and satisfied, so she let herself doze off too.

She woke to Astrid sat up, hair mussed by sleep but expression wide and alert.

"What's wrong?"

"I thought I heard something."

They got up and did a quick sweep, but their home was very much empty save for the twins.

"Huh. Must have imagined it."

"It's fine, we should be up anyway. Dinner?"

Astrid's stomach growled.

"Yes please."

It needed re-heating after earlier... distractions, but it tasted just fine warmed up, and Lillian enjoyed it all the more for sharing it with Astrid. They'd been as close as two could be for several years by then, but Lillian never stopped feeling so lucky, so loved, so happy to be with Astrid.

Astrid wrapped around her like an octopus for bed, snuggles and spooning obviously the only way to sleep for them. In an incredibly good mood the next morning, which was mostly due to Astrid rousing her to wakefulness with an eager tongue between her thighs, Lillian made Astrid's favourite chocolate porridge and promised to bake her protein cookies when she got back from college that day.

"You're the best. Love you!"

"Love you too."

Going to college was nice in some ways and sucked in others - Lillian loved learning, loved her classes, loved all the math and science she got to get her hands on constantly. But her friends wanted to talk relationships, and Lillian couldn't really join in. Astrid had stopped leaving marks on her neck just so Lillian wouldn't have to deal with nosy pushing for details about hickies when she swore up and down there was no boy or girlfriend in the picture.

If it were just that she were dating a woman, Lillian wouldn't have been afraid to say that; her friends were good people, sexuality wouldn't have mattered to them. But when her lover was also her twin, that was probably going to elicit more of a negative response. Lillian knew falling in love with Astrid meant hiding and secrecy, and it was worth it. But it didn't stop that weird sense of isolation when around people who didn't understand that.

Luckily, she always had Astrid to go home to.

Decided to two-part this, part two will be from Astrid's POV.
