[seeing him like this and refusing to touch - at least anything other than indirectly - is like a fucking gutpunch. hawk hasn't gotten on his knees for anyone since he was a little less than tim's age, and he's never wanted to until this moment. not until the pretty pink flare of his cock gets exposed to the warm light of his office, thick and mouth-wateringly perfect. it's not like he hasn't seen it before, but he hasn't seen the precise shade or the shape of it intimately enough to really make him ache. his own pulses in an angry throb of want under his trousers, behind his boxers that have tightened past uncomfortable even as he resolutely tries to ignore it in favor of acting this out on tim and tim alone.]

Yeah. Just like that.

[hawk wants to kiss him equally badly, but he won't give in to it much like he won't give in to his own needs right now. instead, he shifts his hand across tim's to guide it in a loose grip around the base of his pretty cock, lifting his fingers in the approximation of a light stroke to the tip and back down again.]

Good boy.

[it's whispered against him, rough and ragged despite the initial ease of his pace.]

It's yes, sir or yes, professor right now - understood?

[there's a low hum, hawk pressing his chin against tim's shoulder and letting his cheek tip against tim's too - soft skin against one another so he can get a better view at what he's making his student do for him in unspoken commands.]

You get what I give you, if you want to do well. And - don't even think about finishing until it's time.

[another light stroke, hawk shifting tim's fingers in a twist of his palm up at the tip in a lazy moment of indulgence.]
