Lately, Mom has been obsessed with walking. Every time she goes out, she comes back drenched in sweat, and each time I catch sight of her glistening body, I feel a throbbing heat building in my groin. Especially when she gets flushed after exercising or when I secretly see her masturbating, I can't hold back anymore. Her sweaty, voluptuous body seems to beckon me irresistibly.
