Karin is a female student who is interested in kissing.One night, while riding the train, I found a man sleeping in the seat across from me.Inside the empty car...Karin kisses a man out of curiosity.From then on, she repeatedly kisses the man while he sleeps every night.If you keep doing this repeatedly, the man will wake up in the middle of the kiss and the atmosphere will become awkward...The two of them stare at each other, and when their lips meet again, they kiss unstoppably.Close intercourse between the two of them in an empty car.The two of them got off at an unknown station and went to a hotel, where they kissed and sought each other's bodies until morning.
