FORBIDDEN BLOOD

A rare gem of a psychological MASTERPIECE by Psyche Delico. A fucked up family that drives it's members & whoever comes into them insane. The exceptional yet exemplary name & comparison of this manga makes it even more twisted, darker & tempting.
Contains - different types & degrees of Incest. So be prepared for some pretty messed up relationships.

Little Brother x Big Brother
Twisted Incestous love. This one tugged at my heart strings. I find myself repeatedly coming back to this particular work by Ogawa Chise. The state of the older brother's mind, how he tried to contain all the hurt along with his forbidden feelings inside, how the perfect,sweet,obedient little brother accepted his big brother without batting an eyelash and how they drowned in their closed world of guilty pleasure - everything is carried out to perfection!

WARNING I have seen some people getting disgusted with this one as it is true incest. So please, avoid this one if it's not up to your taste.

Son x Father (100% pure incest)
Aside from all that, this is the BEST manga by Ike Reibun IMO! The way she played the time travel card to make us accept this unimaginable incestous love between this pitiful father & son, is just mind f-cking amazing!! A MUST READ for twisted love & incest lovers!!

Brother x Brother
Classic Dark Twisted Erotic Masterpiece where the line between love & hate,cruelty & kindness,right & wrong blurs & all that is left is Raw Maddening Passion.
Voyeurism,Secret Rendezvous,Blindfolding,F-cked up Incest,Threesome,Affair - basically a collection of ALL the forbidden guilty pleasures you could ever think of!
Tragic end

Uncle x Nephew
A pitiful emotionally vulnerable fool of a man, ends up kidnapping his own nephew in desperate need of money to pay off his debts. BUT, his wicked nephew who is too clever for his own age sees right through his weakness and fickleness, & succeeds in seducing & sleeping with him. The twist here is [SPOILER ALERT] the uncle slept with his step sister & his nephew might be his own son!
Contains-Varying degrees of Incest.

Big brother x Half/Step Little brother
It's just a 10 page oneshot but still Aosu Mitsuki managed to masterfully depict the twisted personality & the nature of the characters, their back ground & family history in those 10 pages. Her talent knows no bounds. *RESPECT*

Big bro x Little bro
This one starts of as pretty normal "one night stand" love at 1st sex theme. BUT, gradually becomes darker. As to why I added this manga in this list, has to do something with the plot-twist at the end. I don't wanna spoil it. So please read to find out.

WARNINGdo NOT read this if you can't take parent child incest.
Father x Son
Another 1 of Ogawa Chise's distubingly f*cked up creation.Story of a rotten relationship between a Psychotic Mentally sick father with a traumatic history, who vents all his pent up frustration,anger,hatred & love on his own flesh & blood son. The son too,being brought up by such a "father" becomes deragned & messed up.

WARNING - The MOST FUCKED UP manga of this list. Period!

Son x Father
I am warning you,this is NOT for the faint hearted. Contains different types & degrees of mind boggling incest here! There's a legitimate reason as to why this manga is called "Incest". It might make you want to through up. I was lured in by the beautiful & hot smut but it was trap set up by the devil himself! Trust me, If you don't want a ticket to hell, DON'T READ THIS!
