I love going to sleep with my cock in a slut's mouth. It's easiest with both of us on our sides. I've had a couple of bad experiences with someone who bites down during the night, and that's definitely a rude awakening. My favorite is someone with dentures, because that's not only safe, but feels good all the time. I like waking during the night, feeling myself grow hard, sometimes fucking the mouth and throat for a while, or just going back to sleep. Last thing in the morning is always a good cum in my sheath for the night.
