I adore your way of thinking; I too follow the same thoughts. A big part of my intrigue with the forbidden trope stems from unnatural longing concept of it, the itch that can’t seem to be scratched, wether it’s father and daughter or siblings they’ve been apart of each other life’s since forever it’s like a set bond that cannot be destroyed and then comes the lead up, the itch the infactuation where theirs a level of protectiveness that lingers on the edge of controlling, you both feel it the jealousy and quiet tension but you just can’t explain why exactly you feel this way and it just builds up and up and it’s just pure frustration and pining, you both refusing to acknowledge but at the same time playing at the edge of something quite dangerous, you know what you feel on the inside yet that conditioning from birth and social norms gets in the way :( it’s gonna take a long long time to break down those barriers and why not do it with the person you cherish the most. It’s not rough, it’s not rape, it’s not coercion; it’s simply the softest, undeniable, gentle sin, the gentlest sin that can only be kept a secret. When it gets intimate, it takes a lot of coaxing—convincing each other that this is right because it feels right and no matter what, the love shared between you both will never be tempered with. Then after that, a dad/bro relationship must be so wild and interesting to maneuver, especially since now there’s a blur between the responsibility of a brother/dad and now the Barrier has been crossed to the responsibility of a partner; it gets all jumbled in a mix of confusion imagine dad toji in a predicament: You’re such a good girl around the house, always on your best behaviour n attitude, which makes him want to spoil his little girl with his cock, but he can’t when your grades are so low; he has to switch on dad mode and lecture you but it hurts him because he also sees you in a romantic light so he’s just caught up between two fires. He has to establish a boundary you can’t rub yourself on him or initiate anything when in the middle parent/kid troubles as he may destroy your guts but best believe he’ll set you straight in line when your fucking up on your learning. It’s so hardd to navigate, makes my brain mushy to even think about it ://
