Then he does it again, still so gentle, barely even pulling.

It's good but it's nowhere near enough — Chen makes another tiny sound and doesn't break eye contact. 

Ben very very softly and gently bites Chen's shoulder.

"You can bite harder than that," very quiet. 

"Oh," he says, and does.

His head tilts back and he moans out loud and his fingernails dig into Ben's back. 

Gosh.

What happens if he bites harder?

Chen's whole body goes loose and relaxed and he lets his eyes close and — doesn't keep himself quiet — 

Chen is so good!

He should probably tell Chen this.

He kisses the mark and says, "you're so good."

A sharp gasp at the kiss and a whimper at the praise and a barely-whispered "yours." 

"Yours," Ben says, and bites him again. 

He's — trying not to be too loud — 

He's not really succeeding. 

"You can be as loud as you want," Ben says, "no one will care."

Oh. Right. 

He digs his fingernails into Ben's shoulders and clings to Ben and doesn't keep himself quiet. 

"Can you hurt me?" Ben says. "As hard as you can?"

"That's a bad idea, joints are fragile, but I can —" and he punches Ben in the chest, holds back but not by very much. 

Ben makes a soft quiet broken sound.

Oh, good. 

Chen can do that again — and again — and again — 

He gasps at the moment of impact; he's otherwise silent, his eyes closed, his face peaceful as if he's almost fallen asleep; he keeps forgetting to breathe.

Ben is so so good and maybe Chen should stop holding back at all. 

Ben probably would have some sort of opinion on this if he were capable of thinking at all!

Chen collects him and wraps himself around him, kisses his neck and cheeks and shoulders, plays with his hair, waits for him to come down. 

"Mmmmmrmph," he says eloquently.

"I love you," Chen says, and bites him. 

At this rate Ben is never going to be able to say words.
