The House: Come Find Your Fantasy Inside
by Cassie Alexander
This is a very long, very sexy adult interactive romance novel where you choose your path inside.
It has something for everyone: MF, FF, FFF, MMF, MFM, orgies, exhibitionism, intense BDSM scenes: bondage, whips, sensation play, knife-play, and, if you choose the right ending, one of them's a remarkable HEA.
This book is a fun ride designed to get you off. Repeatedly.
