Mako gasped as his wrists were clamped behind his back. No ropes, there was no need when your brother was an earth bender. As he felt another clay disk mould itself around his ankles, Mako thought about what they were doing. It wasn’t the first time Bolin had bound him. They’d fooled around plenty of times but Mako had always bailed when he’d had time to think about everything. They’d never gotten past kissing each other, he’d always stopped himself. Bolin had finally snapped, surprising him. Mako had been stopping everything because he hadn’t wanted to hurt his little brother but once he’d seen him react like that, he knew he’d been wrong. Sure, Bolin was young and sometimes he got overemotional, but he was strong. Much stronger than him, in fact, and, fuck, he liked seeing it.
