Rose feels Dove's fingers tighten in her hair and lets out a feral growl, a wild untamed sound that echoes throughout the deserted third-floor bathroom that she's claimed as theirs. But she can't be mad, forces herself not to get angry, because she doesn't want to hurt Dove right now. As much as she can force her sister to do degrading things all day, shove dildos and butt plugs in her and send her on her way, she can't make her bleed, can't bite her and let her run back to class with blood running down her thighs. So she lets out a long, shaky exhale as Dove comes down from her climax, and finally pulls away with her mouth and chin and cheeks glistening with Dove's juices.

She straightens, and leans in to press a kiss to her twin's cheek. "That's okay, sweetling. I'll just need to come up with an appropriate penalty for your disobedience, won't I?"
