Jingling Balls.

It's nowhere near Xmas time so it's not Jingle Bells you can hear, but if you listen carefully, it becomes clear that it's these horny boys Jingling Balls as they get down and dirty with each other. Swapping spit with passionate open-mouthed kisses gets this one-on-one party started whilst free hands unbutton and pull off restrictive clothing in an endeavour to get at the taut flesh it conceal and unwrap their early Xmas present!
