"A submissive girlfriend, eager to please, is led on a leash by her dominant partner onto a deserted train. She's made to kneel, her hands bound behind her back, and a thick cock is shoved into her eager mouth. With each jolt of the train, she takes him deeper, choking on his length, tears streaming down her face. She's trained to swallow every drop, and she does, her makeup smearing as she gaps for air, only to be filled again."
