Jade Bleu 
Shared Fertile by Aliens #2: Farrah [EPUB ebook] 

Aliens came for me and fertilized me rough!
I was in the shower, doing something naughty when I found a pair of hot, male aliens watching through the glass. Against orders, they’d come down to the planet to pull me down on terra firma and take me hard in the grass, make me scream, and plant their offspring in my belly.
An erotic sci-fi story featuring MMF multipartner alien claiming, DP with rear entry, fertile fun.
