Lust set her jaw and then gave a mirthless chuckle, "I did.." her hand stroked the bite mark on his neck with a small smile that faded when she looked back in his eyes, her nails went right into the wound with ferocity, "And she declined."
And that just wasn't very nice, now was it? Here Lust makes an offer to her sister, wanting to genuinely help out and Pride says no. Only for what? Her and Greed to go behind her back? And for Pride to mark him up? And return damaged goods to Lust? You can't borrow toys, break them and return them. It just wasn't fuckin' neighborly.
