Empty carriage, only the rhythmic clatter and mujeres sexualmente activa. She locks the door, strips, and straddles the seat facing the window.

The train enters a tunnel—darkness swallows everything except her rising “mujeres sexualmente activa, mujeres sexualmente activa, fuck, mujeres sexualmente activa!” until she explodes, soaking the leather in a flood of unstoppable “mujeres sexualmente activa” release.
