[It doesn't take more than a few seconds for him to catch on to what exactly is getting Derek so frustrated. He can feel the knot pressing against him on every thrust but not pushing in. Kavinsky tries to move, but Derek's still got his hips and he keeps trying to change the angle like that'll help. His forearm presses against the headboard to keep his head from hitting it too hard.]

Hang on, [he gasps out. Asking Derek to stop isn't on his mind but he wants this, he wants to make it work if he can.] Hang on, slow down a little.

[Yeah he knows he's asking a lot here. Kavinsky lets go of Derek's hair so he can grab the lube he's got on the table next to the bed. He trusts Derek not to give him a concussion as he gets it open and gets his fingers slick. He reaches down, trembling just a little as he feels the knot. He gets it wet, figuring a little more lube won't hurt, but he doesn't stop there.

His fingers rub against his stretched hole, and it takes him a minute, but he manages to get both of them in alongside Derek's cock. Taking the knot is still going to be a fucking effort, but he's trying.

Kavinsky's other hand slides back into Derek's hair and he pulls him down until their foreheads touch.]

It's gonna happen, okay? Just--just give me a second. You're not gonna hurt me.
