"Umm... I've been wondering, if you don't mind how about we do the role-playing game with your shapeshifting power?" you asked your shapeshifting girlfriend.
"A role-playing game with my shapeshifting power. Of course, I do. I love role-playing game." your girlfriend answered as she's so excited to hear you said it.
"Wait, really... are you really don't mind?" you asked just to make sure.
"Yes, really, and you're the one who say it, do you wanna take it back?" your girlfriend answered as she's asking back to you.
"Uh... n...no, no no, I was just to make sure if I heard correctly." you answered awkwardly to her.
"Well, you heard it right, silly honey." your girlfriend said. "So, now that you're agree to this, do you wanna start the game?"
"Of course, I do." you answered. "But what should we gotta do next?"
"Well, I was thinking about some kinkies, fantasy, and some weird stuffs I have it in mine." your shapeshifting girlfriend thought.
"No kidding, you're not the only one who saying this, and besides I don't mind if you turn into anyone you want yourself to be." you replied.
"Teeheehee, oh you silly naughty boyfriend." Your girlfriend teases you. "But y'know, what if I become somebody that you don't wanted, I just wanna satisfy and please my boyfriend."
"And I don't wanna disappoint my girlfriend either, I just want us to enjoying each other for the role-playing game, that's all." you replied back.
"Well, I guess you're right, hun. And who do you want me to turn into?" your girlfriend asked.
"I don't know, babe. How about you?" you asked her back.
"Hmm... oh I know who I gotta be." your girlfriend said as she figures it out who she will going to transform into.
