You wake up the next morning

The next morning, you wake up, no longer intoxicated from lust, your body still on his sleeping form. You notice that his phallus is currently erect. If you wanted, you could probably give him a pleasant surprise to wake up to by giving him a blowjob. Or, if you'd rather not take this further than it's already gone, you could always swim back out through the underwater tunnel and not give the man a second thought any time soon. Either way, it's fully your choice at this point.
