Heroine has dated the son for a year. There are quite few sex scenes on page with the son. The boyfriend has "mommy" fetish. Heroine lusts and love after her boyfriends father whole that time. She is O-B-S-E-S-S-E-D in an unhinged way. She wants to be the one for the dad, because she sees how dad (hero) and the wife argue. How the wife is always a bitch to hero.
Heroine discovers the wife is cheating. Follows her around then 2 weeks and makes pictures/proof. She discovers she and her affair partner are going for Pahama for a week, so she plans to stay behind and tell hero everything and seduce him. She trick the boyfriend to go for a trip at the same time also, claiming stomach bug etc.
So she drugs and ties hero up for 6 days. noncon him. Lots of BJ-s etc. Hero is not into her at all at start. Is heartbroken because his wife. Calls her stupid bitch. Anyway stockholm syndrome kicks in and heros inner deviant is unleashed. By the end of week he is doing all kinds of nasty stuff with heroine in his free will. He also tells heroine to kill his wife and affair partner, so they can be together.
She agrees. Lots of unhinged sex on page, including drugging and SA the wife together. Like 50% of the book is pure sex.
Heroine cuts the break lines of the car and one hour later dumps the boyfriend, because he demanded sex and she did not want to "cheat" on hero. Boyfriend punches heroine, almost murder-suicide, but since hero walked in, he only kills himself. He never knew she was with his father.
Investigation etc. It turns out mother and son have been going at it for 5y, since the wife started to treat hero especially bad. Mommy dumped the son and since heroine did also, that was breaking point. It was deemed son killed mommy, investigation closed.
HEA for heroine and hero.
4 stars because hero cheated on heroine with a man (before the murders). He even understood heroine can never find out. Threesome and sex with other ppl were okay when heroine was present, but not without her. Hero wanted to know if he was BI.
