I love uncensored comics where I can see anything I won't see in porn involving humans. Tentacles (specially those penetrating every holes), urethral insertion with uncommon objects (uncluding bugs), BDSM with all kind of injections (including sperm in urethra) and everything with X-Rays (showing Inside or partial cuts). I would appreciate having some of them.
May also include anything related to extreme fetish (piss, scat, bestiality) as comics of real world. I love to masturbate looking at all these fetishes.
Examples:
BDSM : https://myreadingmanga.info/gengoroh-tagame-actinia-man-cunt-eng/ (even if it is a bit censored)
Tentacle: https://myreadingmanga.info/kenkou-wagomu-nemu-shokukan-saint-seiya-dj-cn (again a bit censored)
X-Ray /Cuts: https://hitomi.la/galleries/941433.html (uncensored)
