Heat Sharing (слэш)

Tony learned from a young age that the best thing about an alpha was that they were easy to manipulate. They always thought they were in control and Tony liked to prove them wrong while getting his own way.
Loki was the first alpha who hadn't fallen for any of his gambits, which made him a little bit fascinating and very annoying, especially considering he was an enemy.
But Tony had never thought much of their battlefield flirting, not until he woke up on the verge of a heat with a heat companion all lined up only to have Loki teleport into his tower absolutely insulted at being overlooked.
