I'm forbidden from having sex with my friend's stepmother, but I still find a way to pleasure myself on her

I've been strictly forbidden from getting it on with my buddy's stepmama, but who's to say I can't still get my rocks off? She's got a body that screams sin, with curves in all the right places. Her big, bouncy tits and ample ass are enough to make any man weak at the knees. When she's around, I can't help but be drawn to her, my cock throbbing with desire. But I know I can't touch her, not really. So, I resort to other means. When she's not looking, I sneak a feel of her, my fingers exploring every crevice, every hidden spot. I can't help but moan as I pleasure myself on her, my cock sliding between her soft, inviting folds. It's a risky game, one that could cost me my friendship if caught, but the thrill only makes it more enticing. I'm a true cuck, a willing participant in this forbidden affair. And when I'm done, I can't help but cum all over her, my release painting her ass with my hot, sticky seed.
