ARM-549 - M-shaped leg spread, showing off her panties while giving a handjob, and eventually masturbating herself

When I caught her flashing her panties, she shyly covered up, but I couldn't resist asking to see more. To my surprise, she obliged. As I started masturbating, she stared intensely at my cock. I guided her hand to it, and she began stroking me gently. Watching her spread her legs in an M-shape, fully exposed, drove her wild too—she started masturbating herself while still hand-jobbing me.
