You’re watching the football match with your straight buddy. He’s had too many beers and passes out hard on the sofa, snoring with his mouth wide open.
From your POV: you shake him, slap his cheek - nothing. You lift his shirt, feel his chest and abs, then pull down his shorts… no underwear. His cock is exposed.
You tease and play with it while he sleeps like a rock.
He wakes up only when the match ends and mumbles sorry before going to bed.
A naughty sleep play story.
