My Man often plays with me while I'm sleeping. I always wake up, when we had babies and I was getting very little sleep I wasn't happy about it, now I'm always ready, so it's fun.
For years he told me, "I'd love you to wake me up with a blow job." The only problem is, he sleeps like the dead. I did eventually try it, and it was like sucking on a fat wet noodle.
He didn't wake up.
Every once in a while I do this, and he never wakes up. I tell him later in the day, "Ya know, I sucked your cock while you were asleep. You missed it. LOL!"
