私はオフィスで義理の妹とセックスしました

We were alone in the office when everyone had already left. All that remained was the dim light of the desk and the silence of the empty building. She was wearing that tight skirt that fit her perfectly and the blouse a little open since the afternoon meeting. I couldn't stop looking at her: her legs crossed, her shoe hanging from the tip of her foot, that slow movement she makes on purpose.
