Many of their nights were similar. Bellatrix remained quiet about where she was going and Sirius didn't ask. Their nights ended the same way. Her cool touch and her dark eyes on his perfect body as he lay in the darkness; her nails always woke him up, as she dragged them into his flesh and woke him, riling him enough to want her over and over again. He began to crave her body, the way she moaned and the way her body arched as he hurt her. But no sooner had their summer started, than it ended. In the final week of their summer, Sirius was to go back to James's house as he and his family had returned from their holiday.
They left through the forests, walking on a hot August day through the open forests they had walked in many times over the summer as always. Bellatrix had hunted in these woods, practiced her knife skills and used all of the magic she could without using a wand. Sirius had on a few occasions followed her into the woods without her knowledge, watched her as she ran and practiced with her dagger –how she had improved. By the end of summer, it was safe to say his cousin was not one to cross anymore. He wasn't sure why she was practicing such skills.
Never the less, when they came together, it seemed nothing had changed between them. They still laughed as they did when they were young, still played and fought as they did when they were young. But their sense of freedom was limited to the forest. They were often together in the dappled sunlight of the trees, and it was their secret, they remained there for hours until it was getting dark, and Druella was back from her many social calls and Cygnus was back from work.
"You know," she said to him as they walked through the forests one final time together, "you could stay. Just go back to your mother and father. Tell them you shouldn't have left."
"You know as well as I that even if I wanted to go home, I couldn't. Once you're disowned, that's it, you're disowned." He said, watching his cousin's reaction.
She didn't say anything for a few moments, though he could tell she was thinking, "I could talk to your mother and father."
"What so you can get in as much trouble as me?" he grinned.
Bellatrix rolled her eyes, "I'm not stupid like you, I don't know where you got it from."
They were making their way far out enough of the grounds so that he could apparate back to James's house.
About far enough, Sirius paused to look at his cousin, "No matter how crazy you get... and you are pretty fucking crazy, I've got to say-"
Bellatrix interrupted her cousin, not wanting to hear what he was going to say, "See you at school."
Sirius nodded before leaning over his cousin to press a kiss to her mouth. They hardly kissed, it was too intimate for them –which seemed stupid considering the fact that they were naked in more than one way with one another, but although it was an unspoken truth between them, he couldn't help himself. She didn't stop him either, and as she leant into him, his hand grasped her waist to pull her closer only momentarily.
"Thanks for helping me out this summer, Bella." He shrugged.
Bellatrix nodded, "our secret."
Without so much as another word, they both disapparated; Bellatrix to her room, which now felt so empty and Sirius to James's house, which now felt so strange to be in once more.
