What are the logistics of a surpirse morning BJ?

I've heard guys talk about how much they love being woken up with a BJ in the morning, and I want to do it for my man on his birthday...but I'm not exactly sure how to go about it!! Do I wake him up?? Just head down there while he's still asleep and get going?? Any tips or advice, experiences??

Scott, I usually wake up with a Stiffy stuck into my back and a "Hey, ya wanna?" or says nothing. Or he heads South, while I'm not awake yet. Being a woman, I like to go pee, brush my teeth, wake up, take my morning meds and get a drink of water first, so after he "wakes" me, he usually has to wait a few minutes.

I can't come if I have to pee, so that's necessary. He also needs to plan this Wake Up carefully. If I was up with a fussy baby all night, or something, it is NOT the day to do this.
