Fanfic. Star Trek. The internet is for porn.
It’s a ridiculous romance, involving an intentionally anachronistic Romulan starship pirate’s crush on the half-Vulcan astro-temporal physicist he’s never met, and how a Vulcan raised without the culture of her homeworld takes advantage of our starship pirate to exact her revenge on the astro-temporal physicist’s father. Also, the entire engineering crew is Orions, and they’re great.
But, mostly, it’s porn. Trashy romance novel porn with mind-melds. And a whole, whole lot of alien peen. And like a third of the dialogue is in Vulcan (with mouseover translations that don’t work on mobile, sorry).
