The first time they kiss, it's on impulse.
Taylor is gone, so many others are gone, and Rebecca only survived by chance and-- Lisa wants to.
The healers leave them alone, Rebecca's wounds gone. There's a single moment of hesitation. Lisa's teeth touch her lip, her eyes flick to Rebecca's mouth. Rebecca's eyebrows move upward a tiny amount, back downward after a half-second, then she nods just barely. Desire; surprise, acceptance, permission.
Lisa reaches forward for Rebecca's hand, closes fingers around her wrist as she leans in. Rebecca's pulse remains steady if slightly elevated, no signs of disgust or panic, and Lisa turns her power off after that last reassurance.
(God, her power comes with an off switch now. She'd have Taylor's lesbian babies if she hadn't sacrificed herself another goddamn time--)
It's nice. Rebecca's free hand comes up to cup her cheek, Lisa strokes a light thumb along the other woman's hand. There's nothing sexual about it - neither of them really have a sex drive - but it's another way to connect, a way that had been denied to them before. The kiss breaks, and they pull back, Lisa turning her power back on.
There's a slight flush to Rebecca's cheeks, her smile only evident enough for Lisa to read and read into. Lisa's own smile has no hint of smugness to it, no cruel anticipation before she sinks her fangs in.
The world outside will need guidance and support soon enough, but this moment is theirs.

The second time they kiss, it's deliberate.
Things have settled down. Rebuilding efforts have started, building efforts have resumed, everyone who needed medical treatment has gotten it, the losses have been tallied as best they can be. Taylor's death still stings, the loss of so many heroes haunts Rebecca in unexpected moments, but they're bearable, now.
They mostly spend their time rebuilding, coordinating, negotiating. Rebecca with her new power - Lisa flinches the first time it touches her, remembering Brian and his insanity, but she adjusts, trusts Rebecca too much for it to affect her for long - and Lisa with all the certainty (and relief) of no longer having to manipulate the world.
Time alone is precious and jealously guarded. They often work together - Rebecca has a wealth of experience with a power close to Lisa's, and Lisa herself cuts through problems with a knife when she has access to Accord - but the times they spend out of costume and out of the public eye come few and far between.
When it's just them, alone and off-duty in Lisa's apartment, the powers stay off. They play a game, watch television, read the newspaper or internet articles; in moments such as those, it's hard to tell them apart from any other well-established couple.
Lisa dozes from her spot in Rebecca's lap, back pressed against her chest and body wedged between her legs. There's some Aleph movie on, something about zombies and strippers that no one is sure how it made it into their collection, but neither is paying much attention. Lisa drifts in and out of consciousness, Rebecca quietly enjoys their moment while getting close to napping herself, and then... it just feels like time.
Light fingers stroking her wrist bring Lisa closer to consciousness. She stirs, opens her eyes to find Rebecca looking down at her. Rebecca's free hand lifts to rest against her cheek, her gaze drifts down to Lisa's lips, and the younger woman knows her intent in an instant.
A small smile from Lisa, and lips meet.
Like before, it's intimate rather than sexual, exploring and sharing for the sake of knowledge and closeness. Unlike before, there's... something. A spark.
This time, when they break, it's because they're both mildly confused. Lisa has gotten used to asexuality as a side-effect of her powers overloading her with unwanted details about everyone, Rebecca as a necessary component of making sure no one could manipulate her or Alexandria. Now that Lisa can stop the flow of information, now that Director Costa-Brown and Alexandria are far lower down the list of people most desirable to have in your pocket... there's potential.
The movie reclaims their nominal attention, but below the facade, the minds of two of the brightest whir.

The first time they have sex, it's unexpected.
One of the newly-discovered worlds - Oasis - has a socio-political Thinker in charge of their equivalent of the West. He'd only rate a 5 or 6 on Bet, as best they can tell, but on a world where there are only a handful of other parahumans, most Brutes or Strikers, he's carved out an empire for himself.
It's really not his fault that Avalon and Bet send Alexandria, Crow, and Taylia as their representatives, and he is therefore badly outclassed.
Taylia lets Alexandria and Crow take the lead, only occasionally dipping into the conversation with Avalon's input, and the whole set of negotiations is a slaughter. Bet gets everything they want, Avalon gets everything they want, and every little trap or concession Oasis tries to trick them into fails.
Toward the end, Rebecca can't help but notice Lisa's restlessness. She shuts down the Oasis Thinker more harshly as things come to a close, and the small twitches of her body language scream that she wants to leave. Rebecca can tell by the slight dilation of her pupil and miniscule flush to her cheeks - both signs she's allowed herself, and too subtle for the other two to notice - that she wants something, but she hasn't told Rebecca what just yet.
The two of them retire to their hotel room - expensive and provided entirely at cost to Oasis - and the second the door shuts, Lisa moves.
She slides out of her armor in a twisting motion, careless of where the pieces drop, and turns to her partner. Her pupils are now blown, her breathing faster and heavier, and the twitching of her gut shows she'd rush forward if Rebecca weren't still in her armor.
The second set of armor falls to the floor, and Rebecca tilts her head in a silent question.
Beginnings of arousal in response to yours, starting to find you physically attractive as former self-imposed sexual restrictions wear away. Would enjoy taking control in future encounters, will be extremely aroused if-- Lisa shuts off her power before she can start getting information that would ruin the mood, and lunges.

They figure it out.
If there are words for their orientations, they neither find them nor care to cobble them together out of Latin. Even a few decades of being free of sexual restrictions doesn't leave either of them with normal libidos, but they find ways to spark the mood, on the rare occasions where one or both want that form of intimacy.
When the fifth dead entity appears in the sky, ready for more pairbonds to ascend, it feels like time. They make love one last time, slow and deliberate, branding physical details onto minds that will shortly change beyond recognition.
Then, they leave their bodies behind, riding their deaths into the sky, exulting in the joy of becoming one in the most absolute way.
