My Dirty Little Secret
Charles storms home with a devilish grin, handing Alina a mysterious box that she eagerly rips open—only to freeze in shock at the sight of a thick, piston-driven fucking machine. He pushes her to climb on, voice thick with lust, and after some nervous hesitation she straddles the beast. The relentless, pounding thrusts quickly overwhelm her; she scrambles off, face flushed, calling it too filthy and strange. Disappointed, Charles swallows his hunger and lets it go.
All week Alina keeps vanishing for hours at a time, stirring his curiosity until one night he catches her in the act—naked, dripping, and moaning like a whore while the machine slams into her soaked cunt over and over. Far from angry, Charles's cock surges at the sight. He strips down, joins the fun, and turns their little secret into a sweaty, double-stuffed threesome with his wife and her new mechanical lover.
