   Summary

   "Is there a reason why you're so adamant about getting a human body?" Grace asks in exasperation. "I mean, what exactly do you want to do if you have one?"

   Rocky pauses in his building. Then, with a sound that seems closer to a chuckle than a laugh, he says, "guess."

   ***

   Grace doesn't really know how he gets himself into situations like these.

   But as long as Rocky remains interested in only him, then Grace is fine with fulfilling his curiosities about human sex.

   Right?
