"Well... The new Super Smash Bros just came out, and I've been waiting to play it with somebody. You in?", you ask hopefully.
"Sure thing! I'll get the console started, I guess", she suggests.
"No, no, no! I'll get everything prepared.", you quickly counter her offer, "You just stay here and get comfortable".
You start up the console, turn off the lights, and go grab some snacks for your gaming session, but when you come back, you notice that in the same spot in which your shapeshifting girlfriend was sitting, tapping her phone to pass the time until you got ready, now sat someone completely different!
"Can't believe you transformed again so quickly!", you comment in astonishment.
"Well, I don't like staying in one form for too long...", she suddenly explained with a high-pitched nasal voice, "Besides, we are going to play some video games, and is my gaming bod!"
It was amazing how vast your girlfriends abilities were- the girl sitting in her place looked nothing liked her, sounded nothing like her, and even her body language was slightly different: She had smooth, neck length hair which was platinum blonde up to her brown roots. In this mane was a sweet round face with loving blue eyes that you had never seen before in your life. She was cuddled to a ball, but you could see she was pretty fit and had a nice pair of breasts. She had shining black nail polish on both her feet and her nails, and she was wearing just panties and a sweatshirt.
You decided not to comment further on her new form, as you saw her curled up into a ball like that you asked if she was cold and wanted you to turn on the heating.
"Nah, I'm not actually cold...", she replied quietly in her new voice, "It's just like I told you- when I transform into a certain bod sometimes I get a few changes in mannerisms or speech patterns. Sometimes it's sexy accents or knowledge on different languages, but sometimes it's just... well," she gestures to herself, "this".
You approach her slowly, sit down next to her, take her manicured hand and hug her gently, "Well, I like you in whatever form you are. Because I like the real you- behind all of these."
She looks to you with a tear in her eye, "Thanks, hon. Hearing you say that really meant a lot", she says with a smile as she scrubs her eye with the shirt of her sweatshirt, "Man, this body is suck a crybaby. Let's get gaming already!"
Before starting to play, you decide to make things more interesting with a bet: The winner gets to choose who your girlfriends transforms to when you finally have sex afterwards!
You play for about 2 hours and have a few laughs, argue and cuddle.
Eventually, the winner is...
