Of Knaves and Virgins (смешанная)

Thor has just come of age and is going on a tour of all the Nine Realms. It's going to be great! What could possibly go wrong?
Well Loki could. Of course.
“Nice dress,” Thor compliments, running his eyes over the green silk number clinging to Loki’s curves.
“I’m not wearing a dress.” Loki says, eyes sparkling.
Thor frowns, “What? Clearly you—”
The dress slips off Loki’s slim shoulders and falls to the floor, landing like a green puddle around his long shapely legs.
“—aren’t.” Thor finishes, wide eyed, cock already stirring.
