I Roved Out. Extremely NSFW, it would be categorized as porn. It is an incredible story, and is so despite the porn. The sex is so interwoven with the story, I can’t imagine a SFW version could ever be constructed, which is shame because it’s such good art, and such a great story. I can’t praise it enough. If graphic sex doesn’t bother you, I highly recommend it.
Blastwave. Short, so if you binge it it’ll be over quickly.
There have been other great recommendations I won’t repeat, but these two have exceptional art.
Edit someone else beat me to recommending Blastwave. It’s good.
