"Thank you," Adora harrumphs, reaching back for her discarded shirt to bind Catra's wrists together. It's a good, firm knot -- she paid close attention in those lessons. The same as she does in all of them, really. Bet Catra would've thought twice before calling her a nerd if she knew just what that knowledge would be used for. "Was that so hard?"

But the huffy twist to Adora's smile fades as soon as she finishes the knot and leans back, taking in the sight of Catra underneath her. Oh-- this is a good look on her, too. She blinks down at her sprawled-out form, wide-eyed, before her smile broadens-- slowly but surely-- into a grin.

"I can't believe you let me tie you up," she marvels, with just a hint of a chortle. "You must want this pretty bad, huh?"

Catra definitely won't like that-- so she's sure to offset it by leaning back over and reclaiming her nipple between her lips, sucking down hard.
