Your own mother

While you watch your girlfriend's transformation, you see she grew 4 inches taller than her 5'2" height, her hair was growing too. Her hair, which was shoulder length and light blonde, was now growing a quarter way down her back, turning a deep brown, and appeared to be getting wavy. Next was her breast, which increase from a nice B cup to a full, big EE cup, you didn't realize how big they were. Along with her chest, her skin seemed to darken a bit from a tan, and all excess hair on crotch dissappeared. Her whole body had become more toned. Finally, her face and voice both seem to contort and reform back to that of your mother's image.

Laying on top of you now was not your girlfriend anymore, but the almost perfect naked body of a beautiful 39 year old woman you just happen to call mom. Your girlfriend finally looks over to you and says,"Wow, that was a strange ride, isn't it?" You stopped for a moment and realized that her voice was actually sound like your mom too.

"Whatta, you're turning into my mom!?" you shouted in surprisingly voice.

"Well, yeah... is it really matter?" your mom/girlfriend asked in her childish attitude.

"Well, this is getting too weird for me." you said awkwardly.

Then your mom/girlfriend turning your face to look at her and said to you: "Relax, hun. I'm not your mother, it's just me in the copy form of your mother and there is nothing to worry about."

"Well, I guess you're right, but why not turn into someone else but my mom?" you asked your girlfriend a question.

"How should I put it, um... I thought to myself that I try something really kinky so I turn you into your mom just to try. Plus do you remember that someday if I was your mother so you could fuck me?" you mom/girlfriend replied.

"Wow, I thought I was the only one who keep the kinky stuff of mine own. But once again, you have suprised me, 'mommy'." you finishes before you hold her face and kiss her deeply. The whole experience is sureal as not only are you kissing your mom's body. There is no doubt left in your mind, this is going to be the best vacation for you to remember.
