Bear with me, my brain is everywhere today so I'm probably hella incoherent 😅

So I'm actually really happy about what you said about the brother/sister dynamic bc I was doing my best not to make it smut-trope-y and more realistic. Going by story, Satoru is about 24 and reader is just a little over a year older than he is, so given they are both well into adulthood I felt it would be strange if Satoru were to sit on a lower step than her, especially when he was successfully groomed by his parents in comparison to reader. It felt more right to filter his adoration into the dynamic instead, bc that's what sealed the reader's dependency to him in the first place.

As for Toji, I'm actually going to reveal his stance on his relationship with the siblings in the next work so I don't want to say anything just yet :3

Lots of people really enjoyed getting to see Toji interact with his wife, and honestly I'm super relieved that the jump between the sister reader and the wife reader was taken so well for a couple of reasons. For one I really loved seeing everyone outraged at Satoru hehehe, because after all he's done for his sister it feels like a genuine betrayal (and I won't say it's not one!) As for the other reason, it's mostly because I really wanted to write a jjk gangbang with those four characters and provide conflict and context for part 3.

Everything was much too hot. You were a sweating, shivering, delirious mess. Your clothing felt abnormally abrasive and clung to your flushed skin. Arousal was boiling inside you and you desperately tried to hide it.

"Baby sis, you absolutely cannot go anywhere like that." The sound of nii-san's voice made you freeze with your hand on the handle of the front door.

"I p-promised my friends-" your voice sounds weak, even to you.

"Oh sweetie," the faux sympathy was dripping from his mouth like molasses. "You have to stay home, and let nii-san take care of you."

His hands are warm, one brushing at your hip seemingly innocently and the other placed on your forehead to feel how warm you are. You're mortified when his soft touch makes you moan under your breath and brown eyes gleam triumphantly.

"B-but my friends..." you whimper as his grip tightens, knees buckling and arousal spiking. This was wrong. What was wrong with you? You shouldn't be feeling this way because of your brother's touch, but you couldn't deny that it was heady pleasure burning through your veins as Mori-nii runs gentle hands down your waist, pushing up your shirt and teasing the flushed skin of your belly.

"Doesn't this feel good? I can make it feel much better." Morisuke purrs enticingly.

You visibly blanch, trying to back away from him but your back is met with the door. Morisuke follow unflinchingly. "Nii-san th-that's wrong. You can't touch me like this."

"Why not? I can tell that you like it, you might say one thing but your body says another." His voice is low, and the sound of it is only spurring on your taboo attraction. What's happening to you? You're growing dizzy now, his voice sounding far off to you, you don't quite notice the way it hardens, how dangerous he sounds now. "Are you really going to choose your friends over me?"

You barely bite back a whine as one of his hands dips below your skirt, teasing the waistband of your underwear. "Please, Mori-nii don't—"

Morisuke ignores you, fingers already sliding through your soaked folds, until he brushes up against your pulsing clit. The slightest pressure was enough to make you submit, choking out a moan for more, hips bucking as pleasure makes your mind blank. He's holding something up to your face, and you're so dazed that you don't even wonder how he got your phone. It was already dialed, ringing next to your ear.

"Tell you're friends you can't make it."

You try, but you're not sure how much they understand once his fingers start moving inside you.

"Mori-nii please—"

God he thinks you sound so beautiful like this. You're always beautiful, but you're practically ethereal to him when you're desperate and begging for him.

He rolls his hips again, slowly, basking in your wavering moans, your plush walls gripping him so tightly. He can feel them fluttering around his length and he toys with your clit again, just enough to make you tremble and sob at how good it feels but not what you needed to cum.

You don't even know how long its been. All you could think about was finally getting to cum on nii-san's thick cock. Your eyes were wet with tears as you pleaded with him again, hands tangling into his hair. "Please Mori– I need to cum, I need you so bad nii-san please let me cum."

Yaku hushes you softly, your pleas doing nothing to deter him from his gentle pace, continuing his languid thrusts. "Just a little longer for me okay? Let nii-san take care of you." He kisses away the tears streaming down your face, "You're being such a perfect girl for me, you like being my beautiful perfect girl right?"

"Y-yes love being yours," You whine, trying to keep your hips from bucking up in search of more friction.

"Then just be patient for me pretty girl. You know I'll make it worth it." His voice was warm and soothing, and it was swirling with lustful promise. He groaned softly as you relaxed under him, letting him continue to use you how he wanted. You really were perfect.
