An anonymous wife and her lover board a bustling train, their eyes meeting with a spark of mischief. She's dressed in a prim blouse and skirt, he in a casual shirt and jeans, but their intentions are far from innocent. As the train lurches forward, she begins to stroke him through his jeans, her small hand working diligently. He groans softly, eyes closed, enjoying the sensation of her touch. She unzips him, pulling out his throbbing cock, and starts to pump him furiously, her hand a blur. Passengers around them are none the wiser, engrossed in their own worlds, as she brings him to a rapid, pulsating orgasm. He groans softly, trying to muffle his sounds as she milks him, his cum spurting onto her eager hand.
