That is soooo not all it's cracked up to be. I've done this, and IMO, it's a better fantasy than a reality.
Which reminds me that once, while I was sunbathing on a small beach on Kauai, a sand crab pinched my twat. Damn, I hate sand crabs.
I have sex fantasies about throwing my legs over the arms of my desk chair and offering my bf a fish taco for lunch. (You know, if God didn't want you to eat it, he wouldn't have made it look like a taco.)
