... Kira vanishes, leaving behind the gold ring to fall to the floor. In the same instant, Brooke rematerializes on the bed beside you, still naked and fast asleep. For a few moments you're so happy to see her back to her normal self again that you completely forget about Kira. That is, until you hear her voice in your head.
"Wha... what happened?" she asks. "Where am I?"
Tentatively, you look down between your legs. Sure enough, your penis has changed again. The shaft appears to have shrunken about half an inch, and the heart tattoo has disappeared from the side. Where the skin tone of your entire groin was only a few shades lighter than yours before, to the point that the difference was almost imperceptible, it is now much paler and much more noticeably different.

" Well didn't you say that we could switch every so often?"
"Yes". You say. "As long as we have the ring and don't lose it, the wearer of the ring can switch places".
"Well, why don't we switch every 3 hours. I become Brooke's pussy, then Brooke becomes your dick then 3 hours later you switch back to my pussy. That would give everyone hours of rest."
You think about this for a moment. It did make a lot of sense. Instead of having to go back-and-forth between the two of you, switching places between the three of you would not be so exhausting.
You make up your mind and...
