>>4779324Hmm I've got a tough one for you.
Its a doujin about a guy who fucks his whole family, I'm pretty sure, at least 3 sisters and maybe his mom iirc. He analizes at least one of the sisters with the help of another, if that makes sense.
All black and white art, pretty standard style, I think I remember that all the characters had very realistic proportions and bodies.
Hmm what else. One of the sisters gets knocked out by another using her fingers like a spinning drill into her asshole. Thats about all I remember
