At the same time that Andrea fired the gun, you decided to go all in and tackled her in the legs. Certain of her victory, she yelped in surprise as she fell atop of you engulfing you both in the beam of the gun. You both started to struggle again, but the harm had been done.
Through your struggling you found yourself flat on your back holding both arms of your crazed landlady atop of you with your nose slightly buried in her cleavage. Finally, you arrived at your final height of three inches and, taken aback by you giant surrounding, you both froze taking in the vastness of the space that had become your room. For a moment you were both mesmerized by the gigantic furniture and clothes scattered around before Andrea took notice of the awkward position you were in. Pushing you and getting up in a flash she asked:
"What do you think your doing you fuckin' perv?" Looking angrily at you obviously not shaken by that but by her now miniature stature.
"Hmmpf. I thought the way you dress showed that you didn't care about perverts." You answered confidently trying to make her believe you were somewhat in control of the situation.
"How I dress is not your fuckin' business! And look at the mess you got us into! We are now both as tall a toy figures because of your idiocy!" She shouts.
"My idiocy?! You were about to shoot me in the face with that thing! I reacted normally!" You defended yourself.
"Which wouldn't have happen if you didn't tried using it on me in the first place and paid me my rent like I asked!" She add poking you in the chest.
"Ah whatever, quit your bitching, the gun haven't disappeared. We can still fix this and forget about all of this." You say trying to change the subject.
"Yeah right. maybe you haven't notice, but the thing is fuckin' huge! How are we supposed to use it?" She says pointing in the object in question sitting a few yards from you two. With all due respect for Andrea, she was right. The thing was now dwarfing you as it had stayed normal sized.
Taken aback you started thinking. Moving toward the huge object, you noticed that most of the button were still accessible at your size, even the fire button. You could set it to grow and input a 100% size again. You worked for a few minutes and Andrea watched you intensely as both of you were trying hard not to be disturbed by the hugeness of your bedroom all around you.
"There!" You said. "Its all set to grow one of us back to normal!"
Andrea snorted.
"Yeah that's the keyword isn't it? One of us." She said flatly.
"Well yes, its easy, you fire it while I stand in front of the beam and when I'm back to normal, I grow you back too,"
"Hahaha do you think I'm fuckin' stupid. Sorry, but I don't trust you one second. The way I see it, you are the one who got us into this mess so I get to grow back first!" She shouts.
It was your turn to laugh.
"Hahaha yeah I think not. You're already a pain in the ass when we're both the same size, I don't want to be looking up at your 250ft tall tight ass." You shout back.
"Ahhh whatever you are a little idiot and this is going nowhere!" She says as she starts walking off toward the huge doorway.
"Hey where are you going, we need to solve this problem!"
"Solve it alone I can't stand listening to you anymore!" She shout back.
Whatever, you think, that stupid bitch let me alone with the gun. I will be able to find a solution alone, grow back, find her and get rid of that little pest.
You started looking around, fiddling with the gun a little more, trying to move it or change it's orientation. After a few minutes, not having made any progress, you look toward the door frame and see the tiny form of Andrea finally clearing it and disappearing from sight.
Maybe you were wrong. However you thought about this, the answer was still the same, you needed two people to operate this thing and there was no way that Andrea was going to grow you back with the way things currently were between the two of you.
