This time, a 28-year-old young wife boards a sleeper train. Contrary to her quiet appearance, when she is caressed on the train and her panties are pulled down, she secretes so much love juice that they get dirty and even get thready. During training in the lounge, she exposes her underwear and gets excited even though there are other passengers around. Even after returning to the cabin, her excitement does not seem to have cooled down, and she accepts a cock other than her husband's during an adulterous encounter in a closed room and cums over and over again.
