For those that care, this is the T-rated chapter.

The following takes place a few days after "Come Along With Me."

"HW?" Finn asked at the edge of the trees. "You there?"

She was; of course she was. She'd given him her heart, hadn't she?

From the canopy, Huntress Wizard could see her hero looked worse for wear. His only surviving set of clothes was battered, he had bags under his eyes, and judging from the way he cracked his back as he waited, his bed last night had probably consisted of Jake.

She dropped to the ground and ran to him, let him fall into her arms. She'd wanted to do this the second the battle had ended, but she'd been called away too quickly: GOLB's influence had left messes all across the forest, messes it was her job to clean up. She'd promised to find Finn again. Instead he'd had to come looking for her.

"How are you doing?" she asked when they broke apart.

"Fine," Finn said, because of course he did. "It's been nice. Everyone's offered us a place to crash. PB at the castle, Marcy at her place, even Simon. He's actually moving back into the Ice Kingdom, except he's covering everything with big blankets and setting up some kinda ice hotel. Said something about 'ecotourism.' I don't understand what that guy's going on about half the time..."

He was straining under the effort of putting up a front. Huntress took both his hands. "You don't have to be fine, Finn. Losing your house sucks. I don't know what I'd do without this forest."

"I'm really fine, though," he protested. "It's just, everyone's with their person right now, and…" The warmth filled her even before he said it. "I wanted to see you."

"I'm glad you came," she said to her boyfriend, and despite the circumstances it felt approximately totally awesome. Especially when he smiled. "Wanna have an adventure?"

"Literally I want nothing else more." They passed into the trees, still holding hands, and HW didn't even care that it was slowing her way down.

"Give up your secrets, waterfall!" Finn shouted as he hopped from rock to rock toward the spray. "Don't make me yell at you a third time!"

"You are about to be disappointed, Finn." Huntress hid her smile. "I told you already, I've been back there, and there's nothing."

"HW, I know this is your forest, but every waterfall in Ooo has a secret behind it. I gotta check for myself."

Before she could stop him, Finn had bounded across the last few rocks and leapt through the veil of water. Huntress shifted to her wolf form, sprang after him, and shook hard when she landed on the other side.

She thought he'd splash her back, but when she went nymph-form again, Finn was frozen at the edge of the grotto. "Hey," she said, and touched his back. "You're soaked."

"You didn't tell me it was awesome back here," he whispered, in what passed for his inside voice.

The cave behind the waterfall was as big as a good-sized garden, with granite walls sloping up to a shaft in the roof where sunlight shone down. Luminescent blueflies danced over vernal pools full of frogs and licorice minnows. Small waterfalls cascaded down the sides of the cavern, then disappeared under the ground, where green moss spread in a lush carpet.

Finn peeled off his socks and stepped onto the springy moss. "It's soft."

She kept her hand on him as they walked. With every step, the blueflies scattered, like ripples on a pond.

Huntress realized she was breathing hard. She took his shoulder, turned him to face her.

"Finn…"

He kissed her, the melting kind of kiss, the kind where she could feel the two magnificent people they were flowing away on either side until literally nothing existed but the kiss. They broke apart at the same time-listening to a signal, because it sort of felt like something else was in control now.

She'd already removed her hood, let it fall away as leaves. Gently, she lifted off Finn's hat, let his golden hair fall free.

"Do you wanna…" Finn murmured, "…take off more?"

She nodded. "Yeah."

Without her cloak, her tunic, and her breeches, in just undershirt and pants, Huntress felt the warm air gently tickle her skin. Impatient, she dove in to help Finn take his shirt off.

"Wait!" he said. HW froze with his blue shirt still in her hands. "I remember Jake telling me…we should be careful. Doing this."

Huntress smiled. It wasn't at all like her to feel this off-guard. But she was enjoying it.

"I actually learned a spell for that. I hope that wasn't too much of an assumption to make."

"What spell?"

"It's like a warding spell. Protection."

Finn nodded, smiling too, but trembling a bit as well. "OK. That sounds…that sounds right."

She said a few words, sketched a rune over each of their nether regions, and the ward was finished. Clumsily, they embraced, bearing each other to the springy mossy ground in a laughing tangle. Huntress kissed him this time, enjoying all the places his hands were going. Inwardly, she thought, yes. This is new. But I'm ready.

Outwardly, she said, "Have you ever done this before?"

"No. Have you?"

HW shook her head. "Do you know what to do?"

"I think…" Finn rolled over, pinning her, not helping the problem of her racing heart. "We just figure out what feels good, and keep doing that."

"OK." At some point her lips had parted to let out shallow breath. "I'm ready."

"I'm ready too."

They did that for a long time. And, step by fumbling step, they figured everything out. At least everything important. By the end Huntress felt it only as shards of sensation: a hawk's cry, a ripple of wind over grass, a waterfall plunging down a mountain cataract.

Neither she nor Finn were particularly quiet about it, either.

When at last they at lay together in the grass, spent, with Finn's hair spilling over Huntress's chest, she listened to the whole forest singing them a song. It sounded, for the few fragile moments they'd found, like GOLB had never come to Ooo, like everything was as it should be and always had been.

One moment at a time is all you can count on, thought Huntress Wizard as she and Finn breathed in time. But some of those moments were magic-a realer magic than she'd yet known.

Author's note: the first time at Tier 15 is an important moment in any teen's personal growth, and I thought these two really deserved a positive experience. And since canon didn't address it, I elected to jump in and decide for myself! This is definitely a moment a lot of people have imagined (spiderciderko's tumblr has another sweet version) but it seems like most in the fandom agree that Finn's life experiences and support system would give him a healthy attitude about sex. I also do want to mention that while many fans believe Finn's first time was with LSP in "Breezy," I don't think there's evidence that actually happened, based on comments from Jesse Moynihan and my own viewings.

And that's all I have to say about cartoon characters losing their virginities. For now. Next one will be our first Jake POV!
