“Yeah, I know...” I commiserated, and now that Brucie was no longer in my way I could lean down to give her a comforting hug. “You get used to that part, eventually. Just try to relax, and focus on how good it feels filling you up. He'll start to shrink down pretty quick. You can also put your hand on your pussy, if you want, to hold your lips closed and keep him in there longer. It can help, to make sure he's shrunk down even smaller before you decide to let him out, so he doesn't stretch you so much when he does it. Just don't hold him in there too long, or eventually he'll get annoyed and twist around to nip you on your butt to make you let him go.”

“Good girl, Brianna! Good girl!” she purred, moving her hand back to my shaft. “And since you asked so nicely...” she laughed and started thrusting again, slowly at first but gradually picking up speed. Whatever she'd given me, whether it was Viagra, or ecstasy, or some cocktail of the two with who-knows-what thrown in on the side, it wasn't long before I started noticing the effect. I could feel the pressure building and building, like a heat at the base of my shaft, growing to a fire, then an inferno, searching for a release.
