Horny Alien Monsters Ready to Bang
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. 😍🛸

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 
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

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!
I just realised that the "Villains in Space Series by C. Rochelle" is not on this list and it is a major crime! the LI is a body snatching alien who HAVE A CLOSET FULL OF ALL KIND OF SKIN SUITS! Xenomorph, green bald aliens, Giant merman, TRANSPHORMER, and many many more, and they have fun in amost all of them!
