Put on your spacesuits and get ready to galaxy hop into some filthy alien smut! These romance / erotica reads have monstrous aliens eager to show their lovers a good time. 😈
Not interested in human-looking aliens with a colorful spray tan? You’re in the right list! All books here feature aliens that are weird, monstrous, and truly out of this world. 🔥
For interconnected series, only book 1 is listed. Open to recs!

Note: the Meg Smitherman additions (Thrum, Swallowed) are not your typical romance or erotica. More like horror with romantic subplots. But this list wouldn’t be the same without them. 🥹
Oh hello, I'm just sulking on over after finishing 7 alien cowboy books in 7 days. Not ready to get over my SciFi Romance binge. 😍🛸


Welcome to the monster pit, lil partner 🤠Yeehaw!
I am well versed in this topic and have an 86% overlap on this list, yeah! Here are some of my off the beaten path favs:
Tempting Cargo by Lyra Strake-shes the alien
Toxic Medication by Danielle Stoian
Sheltered in the Storm by Lisa Edmonds
Rent an Alien by Jade Waltz
Bred by the Alien Monster by EK Dahlia
No Strings Attached by Maizy Fell


Also: adding these right meow 😼


Hello, are you my long-lost sibling?! Our tastes overlap hardcore on like every list I find you lurking in LMAO 👯


8 new bangers just beamed up into this list (one’s an alien centipede! one’s an alien bee!)
Here’s what I looked like flying through the galaxy to find these reads 


Note: R. Lee Smith’s books (Cottonwood, The Last Hour of Gann) are dark sci-fi with romance subplots!! Don’t hop into those expecting erotica!
