Naked in local train TRUE STORY

true story not sure you will believe nor not! i will tell any way..
during my +2 i used to go for entrance coaching.. in train,in early morning..like around 430-5am in the weekends..
there will be very few people since it very early morning.. i get very horny..always i felt like i should do something..
one day i boarded and my dream came true, i was the only one in the compartment. it was a local train, so the coaches were disconnected..means if its moving, nobody could enter..
i walked around to confirm nobody is around..
i removed my clothes and became nude! since it was early morning, only a few windows were open. i walked around end to end naked! and cummed after sometime..
