i like incest but the only way i'd enjoy it in rela life is if i found out i was related to someone i was already intimate with, because i dont like any of my irl siblings
there is no such thing as permanent problems (even if its a problem that will have effect for decades of your life) other than some birth defects and some disease, people just not able to handle long term problems.
incest is ok if ur sister is hot because it'll make your kids more attractive due to selective breeding. and all people are attractive to someone, so in conclusion have kids with your sister
just practice being a couple with your sister, continue even after finding partners because you need practice for them too. of course it'll make the sex better! its only for practice even if its sex.
gooning is easy for people who like incest porn, just use ANY porn and pretend its brother sister content. i just goon to those artists drawing their characters with erotic outfits and pretend it a sister showing her brother her outfit, like my pfp.
wearing some stripper shit and asking my brother if i look hot, if he says no i ask whats wrong with my body and ask him to touch. if he says yes i take of a layer and if it still looks good. repeat until im naked. hows the plan?
