After being tricked into a straitjacket and gag, the instructor has more in store for Luna. As she struggles to try and get free, it is impossible to ignore how every curve of her body looks fighting and straining against the straitjacket and leg straps. Her leg straps keep her vulnerable in the spread eagle position- what a delicious treat that she isn't wearing underwear underneath her nylons. Even as she struggles and tries to fight it, it is clear that the bondage and vulnerable state elevate Luna to the plane of pure submission. By the time her instructor helps himself to her pussy by inserting a vibrator and stimulating her clitoris with a wand, she can barely even keep up the charade of a fight and is rendered into a fuck-doll who's only use is pleasure. Her instructor expertly reads her signals, or rather feels with his fingers that she is soaking wet, and begins to fuck her with the vibrator still inside. As he fucks her for both their pleasure, he continues to over stimulate Luna with the wand vibrator on her clit, uses her huge breasts for leverage, grabs her neck just how she likes, flips her over in the doggy-style position, and makes sure she has had multiple orgasms before finally finishing and delivering a cum-shot all over her chest and face.
