Jayce bruising Viktor in various places by accident(or on purpose) because of his strength and how easily Viktor bruises.
The first time it happens was when they were in the lab and(for some reason) Jayce grabbed Viktor’s waist, his grip was strong and Viktor knew that Jayce definitely left a mark.
Viktor afterwards had gone to the bathroom to see the damage that was done. He put his cane against the sink and slowly started to lift his shirt up. A purple-red color was blooming on his skin and it was very clearly two hand prints wrapped around his waist(Jayce’s hands wrap fully around too, I might add).
Viktor’s body immediately heats up and he is so flushed, his face radiating a tomato red all the way down to his chest. He knew there would be a mark left but he didn’t think it’d be that prominent. He touches one of the bruises and then pokes harder at it until he feels the pain. He does it again, and again until he realizes what he is doing and stops with guilt boiling in his stomach.
What’s worse is he wants Jayce’s marks on him. He wants to be treated roughly, manhandled. He wants to relinquish control, to have Jayce someone else decide for him. He wants that pain from these marks, he wants more of it.
And he feels disgusted at himself for wanting it so much. He shouldn’t want this especially not from Jayce. It’s unprofessional, it’s silly even, they aren’t together. He knows all of this but he can’t help the fact he still wants, no, needs this.
He can’t dwell on this now, now he needs to leave and get back to the lab with Jayce and forget all of this and try to stop thinking this way. And so, he hastily tucks back in his shirt, grabs his cane, and leaves the bathroom.
