[request] male POV humans in alien story erotica?

So this seems to be pretty specific and hard to google, hence I appreciate any recommendations – I’m looking for a story told from the male perspective, where two humans get it on in some sort of alien story or environment, so they could be researchers, both being abducted, anything like that.
Think Mulder and Scully get it on in the X-Files, that direction.

Thanks!
