Modern AU setting, Akari is a trainer out traveling through a remote area when she finds another trainer trying to catch a shiny Togekiss. Said Togekiss is clearly in distress and does not want to be caught, but the other trainer has it paralyzed/down to 1 HP and keeps chucking balls anyway.

Akari immediately reacts like "HEY WHAT THE FUCK ARE YOU DOING" and chases the other trainer off before tending to the poor Togekiss. It's still very freaked out and wary around her at first, but she does her best to soothe it, patches it up with a full restore, and gives it some berries for the road. Togekiss takes the berries and gets the fuck out of there at lightspeed.

Later on Akari drops into a pokémon ranger station to report the incident because she's still worried about the Togekiss. The rangers on duty are like "oh right, that one. Yeah we know that Togekiss, he's been nesting around this area for a while. We'll try to check up on him but he's an elusive fucker who refuses to get close to humans if he can help it, so no promises."

Akari thanks them, turns to go, and on the way out the door she literally runs into a gorgeous blond stranger holding a Togepi.

Said stranger apologizes for bumping into her and introduces himself as Volo. They have a meet-cute conversation where Volo says he's just an unassuming hiker traveling through the area, and when he learns that she's a capable trainer he asks if she'd be open to traveling together for a bit. Akari agrees (partly because GOD this man is gorgeous) and the two set off together.

The pair spend about a week traveling together, during which Volo seems delighted by her company and Akari keeps getting oddly-lightheaded around him. Not much, just an overall giddy feeling she chalks it up to a latent crush. Her pokémon also seem weirdly taken with him, but she figures it's just because he's got a knack for pokémon, so she does her best to ignore it and just enjoy being around her new traveling companion.

Then one night during some late-night campfire bonding, the pair wind up talking about his Togepi. Volo says that he's been raising her on his own for a few years now, ever since her mother was killed by a human poacher, and although he loves her she is also VERY needy and high maintenance. She basically doesn't trust anyone but Volo to handle her and he admits that he hasn't gotten a good night's sleep in years.

To which Akari says "do you want me to try looking after her for a bit? Just so you can get some rest?"

Although he's a bit hesitant, Volo hands Togepi over to see how it goes. Upon which Togepi takes a minute to consider things, chirps, and happily snuggles down in Akari's arms.

Needless to say, Volo is relieved almost to the point of tears and promptly goes to crash onto his bedroll for the first proper night of sleep in a long while.

The next morning Volo is in even higher spirits than usual, and suddenly insists on Akari joining him for a "detour" to some ruins in the area. Akari finds this a bit unusual, but the lightheadedness is also much more pronounced than unusual so she goes along with it. She doesn't think much of things as Volo begins leading her far off the beaten path and into an ancient cave system cut into a nearby mountainside. It isn't until Volo brings her to the heart of the caves and she finds a ruin chamber full of books, knick-knacks, and a massive nest of pillows that she realizes something is up.

Akari: "...What is this?"

Volo: "My nest. Or should I say, our nest :)"

Then next thing Akari knows she's flat on her back in said nest with Volo looming over her, and holy shit those are wings coming out of his back. Those are Togekiss wings. Shiny Togekiss wings.

She doesn't get a chance to to react before Volo starts rambling about what's going on. Turns out, in addition to gaining a human form when they grow old enough, a Togekiss can and will fall in love with someone at first sight (because emotions run MUCH stronger in fairy types), and he knew from basically the moment Akari helped him that she was destined to be his mate. In fact he would have taken her sooner if there wasn't his little sister to worry about -- because oh yeah, did he mention that Togepi is actually his sister? Whom he has been raising alone ever since poachers killed their mother?

Anyways he was naturally hesitant about bringing a new mate into the family, and he was unsure if he could really love a human after what happened to his mother, so he figured he'd give it a week, scope Akari out and see how things went--

But hey! It's fine! Togepi adores her! So now Volo has nothing to stop him from claiming his mate as intended!

Akari tries to struggle, but the light-headedness is even stronger than before and all her movements feel sluggish. Volo explains this as Togekiss's inherent "blessing of happiness," i.e. the ambient pheromones a Togekiss gives off when around someone they like. That's why she's been giddy and light-headed all week. He's literally been hotboxing her with happy chemicals.

Oh, and not only are those pheromones are extremely potent when a Togekiss is in love, but Volo himself is not immune to them.

Basically - Volo is high as a fucking kite on his own supply.

So needless to say, a drugged-up Akari is powerless to stop an equally drugged-up Volo who is now so in love with her he's lost all sense of reason. He still wants to make sure she feels good though! He's a considerate mate!

So he just. Takes a vial of aphrodisiac. Drinks it. And then kisses half of it into her mouth. So now they're both drugged up and too fucking horny to think.

Long story short they spend Arceus knows how long fucking each other senseless until Akari literally passes out from the bliss. When she wakes up she's still in the nest with Volo snuggled up beside her, one of his wings draped over her like a blanket. He's also got Togepi on her chest and is softly cooing to her like "yes, this is your new big sister~ We're going to be a family now, all three of us. Isn't that just wonderful?"
