I LOVEEE fugaku x his sons.. oh he’d be so gentle and soft and full of praise with itachi and honestly itachi does not know how to handle all of that.. fugaku would get on his knees in front of itachi, caress his thighs, his hips, tell him how proud he is of him, how grateful he is to have a son like itachi.. he’d gently lay itachi down on the futon, examine his body for any new bruises and scratches and scars and trace his fingers over them, the marks the sign of itachi’s devotion to him and his cause.. he’d lay gentle kisses all over itachi’s body, his face, his neck, his chest, his hips, his legs (but never on his lips bc that’s Too Far).. he’d lay itachi on his tummy and massage the tension out of his muscles, struggling with his evident arousal, with his hips twitching on top of itachi’s ass, but itachi never says anything.. he never says anything, he hates every second of it, every second he has to obey Father’s command, but lets Father do as he pleases, lets Father rut his clothed cock in between his ass cheeks, lets Father come all over his back and get some of it in his hair, lets Father grind his cock between his thighs because that means Father will only cling to him and leave his sweet little sasuke alone.. if being Father’s favourite son means this then he will do his best to meet Father’s expectations so that sasuke can have the childhood itachi never had..
(not to say fugaku would always be gentle with itachi bc absolutely tf not, he’s the first to punish them when he decides his kids fucked up and you BET he gets fucking rough then.. he’d shout and slap and beat and deprive them of common necessities and lock them away in solitary in some fucking broom closet or a cell he built in his basement solely for this purpose but i didn’t know where to sneak this part into this lmao)
