She liked the way he towered over her, neck and shoulders and back bent almost double when she pulled him down against her for kisses. She liked stretching him out underneath her so that his feet dangled past the end of her futon, liked the way his fingers almost met around her waist when he supported her, moving over him, together with him. She liked how wide his grin was, giddy, how it burned the smirks and half-smiles of the Kuchiki household right out of her mind along with everything else as he made her come the first time. And she liked—though she’d never admit it—how unfairly safe it made her feel to tuck herself into the hollow of his body, one of his arms wrapped completely around her as they drifted, afterwards.
