An average person will feel many sensations in this world, either physically and/or spiritually (if you believe in that type of stuff). Before meeting Gojo Satoru, your emotions were still there to remind you, hey, you are human: come and feel us; you can't stop us.
Everything changed after you met Satoru.
Gojo Satoru wasn't normal. Even in your first meeting, even without being a cursed user, you could tell something was off about him in the best way possible. The white hair, the ethereal blue eyes behind the sunglasses, or the fact that he consumed sweets as someone should be consuming water. Even your concerns about diabetes didn't feel necessary with this man.
And then you started dating him. Yes, you, the average human being of this world, the single person in the million of eight billion or more. And he chose you, fell for you, for some crazy idea in his head. You became his new drug in the best way possible. Gojo Satoru could never have had enough of you.
The kisses were intoxicating, and his neediness was that of someone who could not hear the word "no." Satoru would pout like a child, his head down enough that you could see his eyes shining through his sunglasses. And you would say "yes" as if only that vision persuaded you (it was your heart speaking).
Now, fucking Gojo Satoru, that was on a whole new level. At this point, you knew of the curses, the Jujutsu world, and the fact that somehow you are dating the strongest of that universe (?!). Fucking Gojo Satoru was not like fucking your other lovers. Satoru was entirely in during sex. As in head, soul, mind, the total package deal. And it was only fair you gave him the same.

"What would happen to normal humans inside your domain expansion?"
The question is met with curiosity by Gojo, who is wearing his black bandana today. He ponders for a moment, one finger toward his chin (because you said once he looked cute doing it, and he does it every time now). "They probably wouldn't be able to see it. Just feel it."
"Could it be considered safe?"
"Mhmmm, let me think. For some milliseconds. Why?"
"Nothing."
Oh, but Satoru had already perceived your interest. Your eyes did not meet his, and you tried to look away, embarrassed. His smile grew from his side lips until Satoru questioned, his voice low, " Is there anything I should know of?"
"You promise you won't laugh?"
-x-
That's how you end up on top of him, his dick buried deep inside your body. It is already overwhelming, suffocating almost, the air being pulled from your lungs every time your hips meet his, and you weren't even inside his domain yet. Satoru insisted on starting slowly for your safety: 0.1, 0.2 seconds max, according to his estimation.
"Now?"
"Are you close?" You shake your head impatiently, furrowing your brows. "Didn't think so."
Differing from all the other nights, you sense Satoru's tension. He can't relax, not even without you moaning in his ear. It's not that Satoru believes he will hurt you; Satoru has to consider the slight possibility of what could happen if he lost control for a tiny second and ended up frying your brain on accident.
"'Toru. Focus on me." You demand, squeezing his nipple so he can come back to you.
Satoru reacts: he starts rubbing in between in the middle of your legs, stroking your sex in a way only he knew how to do, after weeks of studying your reactions every time you had sex. In less than two weeks, the prick had learned places you haven't even discovered yet. It had to be six eyes, giving your body away like that. Biting where the neck meets your shoulder together with a particular way of fucking you and hitting on the place that made you see stars could make you cum in minutes. You are thankful he is the strongest because Satoru had ruined you for any other person who existed.
"Focus, honey." His voice is steady, his chest heaving up and down.
If someone asked you how a mere mortal felt bringing God to his knees, you would know exactly how to explain. That's exactly how you felt fucking Satoru. Like now, with his hands on your hips, helping you sink inside further every time, your open palms resting on his chest for support. It feels powerful and mythical; his mouth parted away like that, licking his lips from time to time. Satoru is a proud moaner, loud and about - but for this time, his forehead is furrowed in concentration, and barely any noises are coming from him. If it were any other time, Satoru would have helped you or taken control when it had gotten too much for his small patience to handle, moving his hips until you were a blabbering mess.
But now, he has to be focused on not harming you. The situation is even more thrilling if you think like that. Bring a God to his knees because if you don't, he might kill you with his power.
"Satoru!" You moan, needy. A warning that you are getting close.
His white hands raise, and you watch (as always) fascinated as the bandana comes off, even forgetting about your looming orgasm. Gojo Satoru is the most attractive man you have ever seen in your entire life, and if you believe in reincarnation, about ten more lives. He has a smirk on his lips now, happy with the way he affects you. I mean, how couldn't he?
"Domain expansion, Unlimited Void."
Everything stops. The air stops moving, and time stops. You are paralyzed, your eyes wide, feeling everything and nothing at the same time. Your mind goes blank in the total sense of that word; you can't form a single thought. You forget your name, can't remember your parents' names, or where you were born, what you do.
At the same time, everything is being shown to you; your consciousness is there, floating lost in the sky, but you can't grasp it. The only thing you can feel is your orgasm, but even that feels like it has toned down, a small explosion the size of a jelly bean growing inside your stomach.
The next thing you know, you wake up in Satoru's arms, gasping for air, shaking, with tears coming down your eyes. You can't stop squirming, and you realize it is your orgasm, with so much energy that could light up an entire city, spreading in your veins and going back into your brain at a swift speed, amplifying your senses. Then you find yourself staring at Satoru's blue eyes, and your mind goes blank again, but not like when you were inside the Unlimited Void. No, now you can feel everything: Satoru's love, Satoru's shooting his cum inside of you, Satoru's hand gripping your hips, the scream coming out of your throat!
Satoru is murmuring something, praising you, saying he loves you, but you pass out again, and the entire world goes black. Satoru holds you, feeling your heartbeat, not placing his bandana on his eyes, your body twitching unconsciously.
You return to him after a few minutes - if anyone asked Gojo, precisely two minutes, twenty seconds, two exact milliseconds, almost three.
"'Toru?" Your voice sounds exhausted, grateful, and in disbelief all at the same time.
"I'm here, honey. I'm here. You are okay." He kisses your forehead, holding you tightly in his arms, still buried deep inside you.
Later, when you ask, Satoru will answer that he had felt your orgasm within you. He had never seen you so out of this world, literally dumbfucked. He won't confess he got worried for a second and ended up placing you inside his domain for ONLY one millisecond. You also won't confess yet that you wanted to try again, up to 0.3 seconds (normal humans wouldn't survive), but who cares? You want Satoru to fry your brain. Instead, you will roll your eyes at his answer, slapping his arm playfully, and he won't even turn infinite on because it is you. And who is he to ever deny you? You who finally made his life whole.
You that had a God wrapped around your finger.
