"Well how about we-"
*knock* *knock* *knock*
"Helloooo, is there anybody home?" says the person who is knocking and spoke on the front door at your home. You and your shapeshifting girlfriend in your young mom's form are shocking that somebody is here, and you both still naked. "Helloooo, can somebody open the door?" the person outside continue to speak.
"Oh my god, somebody here, what should we do, sweetie?" your transformed girlfriend asks as she's panic.
"Well, first of all, 'mom' we need to dress up before somebody saw us naked, and secondly, please just stay calm, I'll go check it out and see who is it." you replied your shapeshifting girlfriend as she's calm down. Then, you both quickly dress as soon as possible, soon your girlfriend in mom's younger form appears to have some her clothes on a cute nightgown for girl. "Wow, I've never thought my mom would be this cute." you thought yourself as for you dress a little slow because you don't have a power of the shapeshifter just like your girlfriend. Finally, when you both got dress up, you look at your girlfriend and impress her. "Wow, you look cute on your nightgown, 'mom'." you responds.
"Teehee, thank sweetie. I hope you like it my new look and this dress." your shapeshifting girlfriend/mom smiles as you come closer to her and hug her, when you both are about to kiss, the person at the front door still calling.
"Hey, I can't stay out here any longer, y'know?" the person at the door calls you when your girlfriend/young 'mom' tries to reply back as she's almost finished her sentence.
"I think he or she on the door is waiting for you, why don't you go answer it while I stay hid in your room?" your shapeshifting girlfriend asks and gives you a kiss on the lips.
"Okay, 'mom'. Stay here when I'm telling you to come out, okay?." you reply back as she's nodding. "Hey, are you still there, I'm coming." you shout as you go to the door and open to see who is it. But first, you have to look at the peep hole.
