Yes I frequently do that to guys I am fucking. We fall asleep from all that work and I usually wake them up by playing with their dicks. If that doesn't rouse them I start licking or sucking their cocks until they do. I do remember a time it was the morning after New Years Eve that I was so fucking drunk I woke with my date fucking me good and hard. I still was pretty out of it and I rolled over onto my tummy. He just raised my ass up and fucked me from behind. I eventually woke up and I really enjoyed that morning being fucked like that.
