obsessed with will's chain (& i think mack would be, too).
fidgeting with it while he rests his head on will's chest, the charms tinkling as his fingers toy with them, rubbing his thumb over engravings and raised edges.
metal, skin-warm, grazing mack's chest or back while will fucks him. the obscene sound of their skin meeting in sync with metallic jingles. mack, tugging on it, like a leash, when he wants a kiss. will following, easily, eager to please. (sometimes he refuses for a moment, just to see mack pout and whine, before inevitably giving in) once, in the heat of the moment, mack pulled too hard, and the little links snapped and the chain clattered to the floor. mack was distraught, and made will drive to the jewelry store first thing in the morning for a replacement. and an extra, just in case.
mack gifting will a new charm for his birthday or christmas. maybe a star, from his superstar. maybe something with alexandrite, an extremely rare, expensive gem, and one of june's birthstones. it coincidentally has a green shift; shining the color of mack's eyes in the right light. will starts kissing it before each game instead of the cross.
later down the line, a wedding ring. a circle of platinum tucked safely under will's jersey, flush to his heart. when mack sees the chain poking out at the nape of his neck, he thinks about the ring, and his heart swells. will rubs it between his thumb and forefinger for good luck. feels for the engraving, mack's messy scrawl, on the inside.
mack has his own now, a dainty gold strand with his wedding band the sole adornment. will pays him back, and tugs him around by it like a collar. loves the angry red indent it leaves on his skin.
