My stepmother is a sexually promiscuous woman and she is unaware that I am the one purchasing her workout videos in underwear and tights

I've been secretly funding my stepmother's fitness journey by purchasing her workout videos in underwear and tights. Day in and day out, she'd hit the gym, oblivious to my hidden camera capturing her every move. She's a voluptuous vixen, a mix of European and Indian, with a big, luscious body that's impossible to ignore. Her curvy figure is accentuated by her choice of clothing, revealing every curve and contour. As she works out, her tight shorts reveal her ample backside, while her sports bra showcases her generously endowed chest. Unbeknownst to her, I've amassed a collection of videos featuring her in various states of undress, each one more tantalizing than the last. This is a voyeuristic journey into the world of a sexually adventurous housewife, captured in all her raw, unfiltered glory.
