After she sets the dummy down, Sable stalks toward Momo, a smirk on her face. "That was mean. Also extremely good training, and I appreciate you very much."

She pulls her mask up to her forehead, wraps her arms around Momo's waist, and presses a gentle kiss to her nose.

Did you mean "presses a kiss to her lips"?  Because that is what is happening unless she specifically acts to avert such an outcome.

Ooh. Sable likes this plan. She was in fact waiting for Momo to cross that line, trying not to pressure her.

Sable kisses Momo very softly, tenderly, gazing gently into her eyes.

She had been trying not to rush things, but after how unfairly attractive that was, she almost physically couldn't stop herself.

"...I..."

"Sable..."

"Do you have any idea how painfully attractive that was?  Because I do, and it is a miracle I'm managing to restrain myself from doing something that I probably ought not with someone I have known for all of a day, no matter how attractive they are."

"If it's anything like as attractive as a ravishingly gorgeous, heart-stoppingly brilliant pro hero making me impressive gear and putting me through intense training so I can keep up with her as a hero," Sable murmurs, still holding Momo close, "I may have some clue."

"...We might not last the week before the tension between what we both want and what we can trust ourselves to give overwhelms us."

This does not stop her from burrowing into the hug, as if it is the sole source of warmth in a hard cold world, without a single shred of remorse.

"I'm pretty good at... let's say resisting desires. I rather doubt I'm going to be the one to break first here," Sable replies, smirking.

She slowly runs her fingers through Momo's hair. "My headmates and I already know exactly what our decision about you is. We're just trying to avoid rushing you."

Momo experiences the following emotion: !!!!!!!!

It's a very good emotion.  It's just also probably going to make her cry.

...Also, what Sable's doing with her hair feels nice.

Sable sighs happily and keeps running her fingers through Momo's hair, slowly, tenderly, fondly. Inspiring loudly positive emotions in girls you're falling for is a pretty great feeling.

Well, they're very quietly loud positive emotions, but they sure are emotions!

"...I...

"This is really nice.  You're really nice."

"Thank you, Momo." Sable smiles tenderly. "You deserve all this and so much more."

...It still feels fundamentally bizarre, even knowing that so many of the factors that complicated the question in her homeworld enough to render it nigh-moot have been summarily rendered moot themselves - albeit with the introduction of several new, worse complications to her life, because that's just how life is for Class A ... anyone close enough to a sufficiently powerful protagonist, probably - to consider that she has time and space in her life for romance, now.  For something that was not the battle-forged ties of Class A, which would ever be a lodestone.  She had contented herself with friendships; it was best not to risk what she had - her family's accumulated wealth could never buy her friends, nor love, once spoiled.  Would, indeed, do the opposite, and make more friends false friends, even amongst her coworkers.

Ultimately, the thing that still surprises her is that she did not plan for this. Had, indeed, planned the opposite - had planned to love silently, lest she ruin what she already had.

To find herself in the grip of a benevolent aspiring goddess that considered this situation untenable, no matter how utterly fucked the situation was around how...

Apparently, she needs to make new plans.
