Spicing it up with my FWB

So! I need to find a way to surprise my FWB, I'm quite a prude - never given a bj, know he'd love one. Never really do much more that girl on top, doggy and him on top - in the bedroom. Not really one for being spontaneous and we don't have sex outside the bedroom. I want to surprise him in a good way! I'd love to wake him up in the morning, rolling onto him and waking him up for some early morning fun. Any ideas and tips please. He's my first and only so pretty inexperienced.
