Her small suitcase alternated between bumping her shins and bashing against the sides of the narrow stairway as she maneuvered up to the sleeper car. A short walk down another tight corridor and she found her compartment. When she opened the glass door, the lower berth was already made up. She closed the door and the privacy curtains, stripped off her clothes, slid between the sheets and fell asleep, lulled by the rocking motion of the train.
The moon was still high in the night sky when she woke up.She reached for her phone to read for a while and caught the edge of the curtain, revealing a small section of the dimly lit hallway. She looked across the hall and saw the curtains on the room across from hers were not quite closed. Her curiosity got the better of her and she peeked into that room from her vantage point in the dark.
Her phone was soon forgotten as she figured out what she was watching. She couldn't see his face but from the flickering light of what she thought was a tablet or laptop, she could clearly see his hand moving up and down. She assumed it was porn when she looked a little closer and watched his cock grow harder and larger as he touched his erection. She watched, fascinated, as he continued to stroke himself as the train swayed over the rails.
She wanted to see more and wished he'd open the curtains just a bit wider. Watching that hand pleasuring a cock was one of the hottest things she'd seen in a long time. So hot she found herself caressing her breasts, touching her nipples in time to the strokes of his hand on his cock. She fantasized she was being watched by him as she fondled her breasts. She imagined he could see her nipples as they tightened into hard little buds. She pushed the sheets down so she could play with her pussy and didn't notice she'd caught the edge of the curtain along with the sheets. The curtain was almost half open, letting anyone who was looking see right into her room. Her naked body was almost fully exposed in the dim light.
She opened her legs and her forgotten phone dropped from the bed and clattered to the floor. Her hands stilled and she listened for any reaction in the dark. When she didn't hear anything, she scrambled for her phone and stashed it back in her purse. She turned back to the door and discovered the open curtain and the room next door which now also had that curtain open so the occupant was also exposed with only his face still hidden.
