Dear friend gets taken in library

Everyone who saw them, because no one really knew them, could tell that they were a couple of nerds who were always in the library, cramming books and doing homework. However, no one suspected that this tender friendship hid a relationship of power and pleasure that they both wanted to live to the fullest. It all happened once in the library, because there was a time when they went to the library to study, but that day she was perched on the stairs and noticed his lustful eyes as he gazed at her long legs.  There was no way that this maelstrom of pleasure could stop with them.
