Kill Switch by Penelope Douglas

you’re bad for liking it when you knew you didn’t.
I shot out my hands, grabbing her hips and lifting my head
as the blade threatened to sink into me. “And I killed her for
it,” I told her. “So do it then.”
She breathed hard, and I could feel her grips shaking as
she held her weapons.
“Because I won’t stop,” I said quietly, smelling her
shampooed hair.
She’d showered, all the makeup and the costume now
gone, replaced with silk sleep shorts and a white T-shirt with
her hair still wet.
“Do it,” I egged her on.
The sharp points burrowed, threatening me, and I loved the
view of her like this. Taking control of me, her power painful
but demanding, and I wanted her to demand anything she
wanted from me right now.
My cock started to grow hard under her, drawn to her
warmth as she sat on me, and I was very prepared to let this
happen again tonight. Just for tonight.
She came to me, after all.
“You weren’t lying,” she finally said, looking thoughtful
like a memory was playing in her mind.
I’d told her in the janitor’s closet seven years ago that I
killed my mother. She thought I was talking shit. Now she
knew.
“When did it start?” she asked, her brain deciphering what
happened.
But I wasn’t going there. Never, ever again.
“In the fountain when you were eight and I was eleven,” I
told her.
“That’s not what I meant.”
“That’s all that matters.” And I dug my fingers into her ass
as I lifted my hips and pressed my cock between her legs.
