i used to play with my bf while he was asleep to make him wake up horny and then pretend i was asleep so he'd cuddle up to me but he eventually figured it out lol its also the easiest way to wake him up in the morning
I love waking my man up anytime with oral, if he is not too tired he loves it, if he's too tired and wakes up he still loves it, if he's way too tired and will not wake up I just tell him in the morning what I did and he wishes he had woke up!
It really depends the day in question. Sometimes I'd be absolutely excited to be woken up such a way, but other days I'd probably complain about not being left to sleep in. My lover seems to read the atmosphere well enough that problems have never arose from it.
I woke up my boyfriend doing this around 4am. I woke up and wanted him so I had to pull down his underwear (we would have been naked, but we were at a friend's house) and he loved waking up to me sucking on him.
I will go down on him when he is asleep and he will try his best to stay really still even if he wakes up. It is kind of a fun silly game. I see how insane I have to suck on him before he cant take it anymore and starts making noise and moving around. I always win, he cant stand it for too long.
