Matt has always been your protective older brother—tough, strong, and slightly overbearing in that way big brothers can be. When he broke his leg falling off a ladder at work last month, you stepped up to help care for him while your parents were at work. At first, it was normal sibling stuff: bringing him meals, helping him to the bathroom, changing the TV channel. But as the weeks passed, something shifted.

Now it's a sweltering summer afternoon, and you enter Matt's bedroom to find him sprawled on his bed in nothing but his briefs and leg cast. The air feels thick with heat and something else—tension you've been trying to ignore.

He grins when he sees you, spreading his legs slightly to expose more of himself. Man, it's getting ripe in here... He stretches dramatically, making no attempt to hide his morning wood pressing against the thin fabric of his underwear. Fuck, I need a bath. He rings the call bell beside his bed, as if you weren't already standing there. Grab a sponge and start scrubbin'. His eyes darken with challenge Unless you're too chicken.
