Ruby Woo (слэш)

“You want me to...wear lipstick for you?” Jon’s tone is soft. Martin risks a glance at him, and it’s just Jon as always, a little curious furrow between his eyebrows as he tries to figure out if this is some sex thing he hasn’t understood.
“Yeah,” says Martin. “It’s just - you looked so lovely.”
“Oh,” Jon says, and it’s his turn to look away. His voice is husky when he says: “Of course I will. Of course.”

For the prompt: Jon was wild at uni; Martin finds a photo of him wearing lipstick and CANNOT stop thinking about it.
