A Special Encounter at the Train Convention

You visit the Train Convention at Nimbasa City and unexpectedly meet the Subway Bosses Ingo and Emmet. You get along really well with the twins and they propose to spend the day with you. Throughout the day you develop a crush on the bosses, but what happens later that day is something you wouldn't even dream of.

This story starts off pretty innocent and cute, but things get pretty wild in the second half.
