Hehe...
So, King Sukuna sitting on his throne, legs spread and still clothed, watching Gojo fuck Yuuji on the floor. Yuuji's hands are bound above his head so Sukuna can see everything. Yuuji's face is red from a mixture of embarrassment and pleasure, trying not to look at Sukuna as Gojo bounces him on his dick.
And Gojo...he's having all sorts of fun. He's kissing yuuji's neck, telling him how good he's doing, how beautiful he looks, that he can come as much as he wants. Because Sukuna is having more and more trouble trying to hide how aroused he is seeing their balls bounce and hearing the wet squelch of Gojo sliding into Yuuji's ass.
