Sagittarius.Shown's GranblueFantasy doujinshi, anal fisting play with Narmaya. Kinda made me feel the same pain as if I'm Narmaya... Though how to bear and embrace the pain is almost 101 class of anal sex, what happened in this doujinshi would be pure torture in reality.
Guys, just cherish the guy/gal who say yes to your anal sex request, they are angels. Oh and, don't swallow anything leaking out from butthole, do several enema clean both before and after anal, and most important, use more than enought lotion while take it slow~
