#8 - Marital Secrets: Bellatrix/Petunia
[The first breath of adultery is the freest; after it, constraints aping marriage develop.]
It was during Lily's wedding reception that Petunia first saw Bellatrix.
Bellatrix met all the typical witch-like requirements. Tall, with thick, ebony hair that spiralled down to her waist, and large dark eyes, with heavy hooded eyelids and thick, long lashes. She was clad head to toe in black, despite being at a wedding, and stood with her arms folded across her chest, smirking around the room.
Her presence was captivating, and Petunia was forced to ignore her husband's protests as she watched this woman crook her finger to the bride.
The older sister followed the pair quietly, and soon found herself lurking in the doorway, watching ahead as Bellatrix pressed Lily against the wall with her weight, taking a lock of her long auburn hair, and swirling it around her fingers. To Petunia's shock, the dark-haired witch crashed her lips against Lily's, causing the latter to gasp involuntarily into her mouth. They kissed heatedly for a few minutes, but when Bellatrix's pointed nails fingered their way down to Lily's breast, she pulled away. "I'm married now," she murmured, panting heavily. Anger sparkled in Bellatrix's eyes, and for a moment Petunia expected retaliation – but instead she stepped back.
"Then get out of my sight," she hissed, pointing to the doorway, where Petunia stood. Lily ran, hitching her ivory skirts around her knees, and collided with her sister.
"P…Petunia…" she whispered. There were tears in her eyes, but she didn't wait for a reaction, choosing instead to barge past her.
Bellatrix loomed forwards towards Petunia, humour evident on her face. It was only then that Petunia realised she was holding her breath, and that something unusual was stirring in the pit of her stomach. The witch reached out a skeletal hand, and stroked Petunia's bony face, slowly.
"Did you enjoy the show, muggle girl?"
Petunia didn't answer. Her heart was thudding in her chest, and her blood was pounding in her ears. Bellatrix hovered forward, until Petunia could feel the breath on her lips. "Come with me, Lily's sister. I'll show you how to have a good time."
