Alien Shadow Market
Trigger warnings:

• Forced Breeding involving the use of chemicals and machines that force the characters to have sex with each other.
  
• Dubcon moments of sniffing, licking, and intimate touching without explicit consent due to alien characters having trouble understanding and controlling their urges.
  
• Spanking, and lots of it, both with a riding crop and with hands.
• Violence. There are some action scenes with violence and a bit of gore.
  
  If you have read the previous books in the series, you'll have some idea what you're in for. This story is perhaps slightly edgier and slightly more angsty compared to the previous two books in the series, but still very much in the same vein. (And there's quite a bit more spanking in this one.)
