Lots of monsters and sex and more sex

A fun romp through a world where the monsters and demi gods of mythology rule the criminal underworld (not THE Underworld. That's still Hades thing.).
I thought this was an interesting take on Cerberus, three men who could form one massive monster. The last bit where they're uh, frolicking, is a wild ride.
The entire story was fun though, from the moment our thief meets Cerberus, all the way to the end.
A good read for lovers of monster Romance, and reverse harem romance.
