He wears a chain. Nothing too big or flashy, but the metal catches your eye easily. It hangs a little under his collar to the point where he can put it over his shirt.
It dangles prettily over your head the first time you fuck, swaying back and forth, almost like it's hypnotizing you. The metal shines dimly in the dark atmosphere, and you can feel the chill of it when your hands reach behind his neck.
He's rutting into you so nicely, panting, and groaning about how pretty you are underneath him. His mouth rambling on into small curses the closer he gets.
That's when you pull it.
You tug on his chain ever so slightly, bringing him in for a kiss that leaves him whining, lightheaded. He's moaning into your mouth now, thrusts losing rhythm, but your hold stays firm. It's like he could die there, leaning his head onto your shoulder where you can hear just how needy he is. Fuck, it's pretty, and you just know he can feel how much wetter you just got.
You can't help but tug a little more, teasing the whines out of him until he cums.
baby, you're his collar.
