This is immediately going to Ruiverse x original!Tsuka which is always a delight of course 👍 and well, with how much Rui loves his Tsukasa-kun, they all would immediately want to get as near of him as possible and know more about him, since he clearly doesn't look like the Tsukasas they are used to. They would also get jealous and mad at each other because of this... Maybe everyone thinks this is "their" Tsukasa, just looking a bit different and nothing more, it would be a funny idea. And Tsukasa almost having a heart attack because what the hell is actually happening with so many Rui's around him? But of course, we all know this ends up in a Tsukasa gangbang 😔🙏 how it happens it's up to you, but I want to think about how some of the Ruis would act...

Ringmaster🎈: The first one to approach Tsukasa. The moment he set his eyes on him, he saw a new prey to tame. He's surprised to find out how different this Tsukasa is to the one he's used to -a bratty, provocative mess-, so he has to hold back on his usual sadistic demeanor and techniques, and although he is mean enough to make o!Tsukasa cry, he does so through pleasure.

Sorcerer🎈: Quite desperate to know more about this Tsukasa, who seems so weak and easily scared, compared to the Tsukasa he knows. He was genuinely curious, but that helpless attitude also wakes up his hunger for the boy, his need to see him ravished, to test his expressions and to hear him moaning because of his cock. He doesn't wait too long for the chance of acting upon his desires though, and is quick to grab his hips to proceed to fill his tight holes.

Gashadokuro🎈: After analyzing the situation and being aroused enough, he makes his move when he knows that this Tsukasa is just as sweet and sensitive as the one he knows. There isn't much difference between them, he notices, so he goes for one of the places he knows the boy will be very responsive to: his little perky nipples, taking one between his lips and pinching the other, just the way he would pay attention to both of Kori Tsukasa's nipples.

Staff Officer🎈: At first he doesn't show any interest (or so he wanted the others to think) but after a while, the tent in his pants and the blush on his face are almost impossible to hide. Begrudgingly, he makes his way in between the rest and decides to take his place and fuck Tsukasa's mouth, although he could almost feel guilty about how easy it is to make Tsukasa cry and choke every time he shoves his hard cock into that tight little mouth... Officer Tsukasa is definitely much more resistant to such things.

Dark Lily🎈: He was too afraid to get near Tsukasa at first. He would also bashfully call-out the other Ruis when they get too rough with Tsukasa... only to be ignored, since everyone is way too horny in the end, and Tsukasa is enjoying it anyway, so... Prompted by the rest, and not being strong enough to resist, he takes his turn in that sweet pussy, which feels just as amazing as the one he's used to. At this point he forgets all restraint and reservations he had, as he fucks Tsukasa senseless while crying in pleasure and asking for forgiveness to him, lol.
