Don't misunderstand her; she wants to be loved for her intelligence, for her scientific capabilities and for her inner virtues. This is just her way of saying it
Torn between humiliation and supreme pleasure. It's not even physical. She just loves to see him happy so much, she loves knowing he's pleasuring himself in her ass. It's even better than she feels used and degraded.
Want that loving smile? Give her the valentine's day gift that keeps on giving. Show her her place. Treat her like a cheap slut. It'll be the best gift she's ever received. Better than flowers.
