"Umm... can you change into every different people when we're having sex?" you asked your shapeshifting girlfriend.
"Oh, honey that's really kinky, I like the sound of your idea. Come to think it, I've never tried it before, but okay, I don't see that's not a bad idea." your girlfriend laughs as she says yes. "So, honey. Now that you're saying this, it makes me feel so horny, what do you have something to say to me before we start?"
"Well, let just say let's have sex and less talking, babe." With that, when you finish your sentence as you and your girlfriend begin to kiss passionately. During the kiss, both of you strip off all of your clothes and completely naked, once you're both naked, you both broke the kiss and look at each other body. "Wow, I've never do this for a long time when our parents were around." your girlfriend said. "You like what you see?"
"Yes, I do." you answered.
"Well, you better be ready 'cause I'm about to turn myself into someone you're going to see." she said as she's going to use her shapeshifting ability to transforms herself.
