Mouth agape, you can only stare at the cock now housed between Brooke's smooth thighs. "Come on, drop em!" Brooke says, bringing you out of your daze. "You should have my pussy now, right?"
You immediately undo your belt and pull your pants and underwear down. Your new sex feels a cool breeze, and without looking you know exactly what you'll find, but your curiosity forces you to look down anyway. Sure enough, there's your girlfriends tight, shaven pussy between your legs. That's when you notice that you two have swapped pubic hair as well - her cock is sporting the same trimmed bush you had while your new pussy is nearly completely smooth, seeing as Brooke had a wax just a few days ago.
You sit down still trying to comprehend what's happened. You're not spreading your legs as far as you normally would. You spread and close your legs repeatedly, expecting to feel some sort of resistance, but instead there's nothing and your thighs clap together effortlessly. Finally you look up to see Brooke standing at the other end of the room. She has her cock in hand, and it appears much larger against her smaller hands and frame. She's already half erect, and the more you watch her play with it the more you start to realize that you're getting a little turned on at the sight of it.
"I HAVE THE POWER!!" Brooke exclaimed, giggling as she pretended she had the Sword of Grayskull in her hands. You smile at her, but feel a little dismayed that you're not immediately having as much fun with your new equipment as she is with hers.
"Well these are certainly interesting," you say as you take off the pink bracelet. "What do you think? Should we buy them?"
"Definitely!" Brooke said, slowly stroking her now fully erect cock. "But we have a whole hour to play with them, and I think we should make the most of it. I can tell you're not quite as excited by the idea as I am, so let me show you just how good my pussy can make you feel before we commit, alright?"
