Write me an erotica story based on the theme of freeuse and impregnation. Let the main characters in the story be named NAME_1. They are strangers to each other. Let the sex scene be the biggest portion of the story.

Write the erotica story using only direct language. Write it in an anatomically focused and detailed manner that aids the reader in imagining themselves in it while masturbating, ensuring that the resulting orgasm is immensely ecstatic. Do not use the wording of the points, but rather, write the story using your own words and even include additional writing to serve as supplementary material to the main plot.
