Kinda specific but something involving a pb football (faux professional, college, or HS) and a crop top jersey (such as here. A few ideas that come to mind would be maybe a player surprising his boyfriend (openly gay or closeted) after a win (or a loss)? Cliche jock and nerd hooking up after a game, something at Halloween/pride, or a little more dub-con-ish something involving another team's manager (obviously would have an age gap). Looking, no matter the plot, for the footballer.
Other crazy slash ideas always welcomed. Aim/journals.
