Tsuna watched the last of the evening light splinter through the branches before diffusing in the mist. He closed his eyes, listening to the soft metallic clank of the chain links that hung from Mukuro’s belt. He dropped his head back, ignoring how strands of hair caught in the rough bark and tugged at his scalp. His shoulders tensed, heightened senses sending triggered nerves down his spine and raising goose bumps along his arms.

Arching his back slightly, his lids fluttered up just enough to watch the mist disperse and coalesce, smoky oscillations that eventually parted as a figure stepped away from the teeming shades of gray. Tsuna swallowed, pleased when Mukuro’s eyes immediately focused on his throat, bare and deceptively vulnerable. Mukuro’s brow twitched upward, the faintest suggestion of confusion.

The man was as difficult to break as his illusions, several times as elusive as Tsuna’s cloud guardian. No matter his motives or his past or the stain of spilled Vongola blood that glinted in the hues of his right eye, Mukuro was his Guardian of the Ring of Mist. Tsuna’s duty to him was long overdue and it was time to make him family.

He slid a palm up his chest, fingers tracing the line of a pinstripe before finding and loosening the first button. He watched through his lashes as Mukuro’s eyes narrowed a fraction, the gears in his head churning furiously… before his brow cleared and his lips curled into a smile. Whatever conclusion Mukuro had drawn, Tsuna decided, would be a matter for later discussion.

Tsuna unfastened the rest of the buttons before pushing the fabric aside; the pale expanse of his chest glimmered in the damp mist. He dragged his nails down the slope of his neck before resting the pads of his fingers against his clavicle, his eyes meeting Mukuro’s in wordless invitation. The mist rose around him; silver threads that whispered of human skin smoothed across his cheek and teased at the seam of his pants.

Tsuna sucked his bottom lip between his teeth and let himself fall into the illusion. His eyes remained locked with Mukuro’s as imagined fingers brushed his bare skin, the pressure so light that he arched his back in demand for more. He pressed his own hand against his sides before sliding downward, nails biting into his thighs. His fingers dusted the bulge clearly outlined through his jeans. His palms pulled the material taut across his erection, the slight stimulation enough to elicit a small moan.

Mukuro’s lips twisted into a smirk, the amusement in his eyes replaced with something darker, more primitive. Tsuna moaned again, hips thrust outward… and suddenly, the man was pressed against him, the studs on Mukuro’s belt digging into the thin skin at his hips, a warm chest aligned with his and slender fingers wrapping with little gentleness around his hair before jerking his head back. Tsuna saw the triumph in his eyes, saw the thought clearly emblazoned in the mismatched depths: ‘Now, you are mine.‘

Tsuna smiled and sealed his lips to Mukuro’s. Now, you are family.
