Derek couldn't help but be pleased, even awed, by the way that Allison fucked herself on the toy while taking his cock. His eyes fluttered shut in pleasure, dark lashes contrasting against his skin as his lips parted, giving himself over to it, letting her pull his orgasm from him, letting her earn it.
"Always," he murmured, then swallowed, opened his eyes again to watch his cock disappearing in her willing mouth. "You're always going to need this, Allison," he said softly. "To be taken. Used." He hand moved, fingers brushing her chin, tilting it up as he fed her his cock, a gentle caress. "To serve someone who cares for you enough to degrade you."
