Of course he wasn't going to stop. There'd be absolutely no stopping until they were both sated and happy, and curled up in a mess tangle of limbs. Ben knew that Klaus was just saying it because -- because sometimes you just had to say something, and that was the best option.
So, yeah. He didn't stop, in fact, when Klaus got to actually moving along with him (Ben knew, of course, that he'd been holding off just for the sake of being polite), he twisted his wrist a little, experimenting with weight and speed but ultimately not switching anything up so much that it wouldn't still feel good for his brother. That was very important to Ben for a million different reasons.
"C'mon," He said, lips pressing against Klaus' shoulder.
