With only the thin windowpane separating them, the cuckold's tiny dick juts out, his wife's gaze burning into it. He strokes, his small hand struggling to encompass his puny cock, while she leans against the glass, her breath fogging it up. The risk of discovery fuels his arousal, his strokes becoming frantic. His wife, meanwhile, can't help but compare his meager length to the hung men she fucks behind his back, her pussy clenching with desire at the thought.
