At his reassurance, Lily sighed, though the thought of being on display, exposed, added a wild thrill that made her pulse race even harder. Her heart pounded, her breaths shallow, while Arthur's thrusts grew stronger, her legs shaking until she knelt, yielding fully beneath him.
"Ahh…" Arthur groaned, watching himself sliding in and out, savoring the sight of her body surrendering, flushed and trembling beneath him. He leaned down, driving deeper, feeling her quiver around him as he reached her ear, his voice a taunting whisper, "Are you getting turned on just thinking someone could see you? You're getting even more wet… do you want to be watched?"
