I once passed out going down on my gf. Not just once either but it kept happening. I had been on the greyhound for 23 hours and hadn't slept the night before either. She and I got down to business as soon as I got into town. Its kind of like when youre so god damn tired that your head just falls forward but you wake up from the falling action, know what I mean? Anyway, she didn't know that I just kept conking out ever minute or so on her. She was so sweet and accomodating "Its ok if your tired you don't have to." Needless to say I refused to stop until what I set out to do was done
Gotta admit its pretty comfy down there, warm with soft smooth legs on both sides. Not a bad place to sleep
Oh, forgot about the actual question...no but depending on her pace it can be SOOOOooo relaxing.
