Amy thinks it's Keiko with a strap-on

"Unnnnh! Keiko!" Amy whines drunkenly, as she pushes her hips up to meet yours. "A strap-on? You naughty girl!"

You chuckle to yourself as Amy keeps her fantasy of you being Keiko intact. You drill her good.

"Oh, Keiko, you haven't used the strap-on for weeks! It feels so good," Amy's sexy voice just gets you going faster.
