He sunk into the sand. Lock let her grab his wrists, choosing to behave for the moment. He let Lillith get herself situated and relaxed under her. His smirk became a grin as he took in the view, though part of it was a ploy to get Lillith's guard down. Once her confidence was assured that he wasn't going anywhere, Lock lifted his head out of the water. The soft sand and cool waters shifted under him, and he knew he had an advantage. "Who said they were for me?" Unlike the stone floor of the crypt, or the firm inside of her coffin, Lillith couldn't hold him against the soft ground as easily. Lock shifted his body enough to slip out from under her. Normally, he was content enough to let Lillith have her way with him at this point, but after the stunts with the lake monster, he was feeling particularly vengeful. Lock pulled his arms close together to bring Lillith's together as well, and used his tail to bind her wrists. In a quick twist, he broke his own wrists free, then grabbed her shoulders to push her down in an attempt to reverse their positions. His options were always to fight or stay down. Lock gave her a devious smirk. Tonight, the former sounded more fun, and when he wanted to, he could almost match her strength.
