Should I wake him up with a bj?

Me partner mentioned a few weeks ago (very enthusiastically) that I have permission to wake him up with a blowjob.

Then, last night, he jokingly said that he would only wake up in time if “someone sucked his dick”.

Well. It’s 6 A.M here. He has to be up in about 40 minutes and I’m considering trying. But I’m a bit worried he won’t like it still.

Should I go for it? I’m worried that he only liked the idea in theory but in practice would feel violated.

Edit: I did it! It was amazing. Thanks for the encouragement.
