Turn your mom back to normal.

Your girlfriend replied with a smile "Yes, but I need you to put things back to normal, so everything is cool."

"That's it?" you asked.

"Of course, do you want to take it back?" she asked you back as she's crossing her arms.

"Well, no I was thought that you might have to do something weird so I make sure I was hearing correctly, but okay." you said as pull out the ray-gun and aiming at your teenage mom while she's still standing there near her car. Then, you shot at her quickly while you still can.

After 30 seconds later, your teenage mom is finally back to normal, plus her clothes are also back to itself. "Oh dearly dear, what happened, what am I doing out here?" she asked herself as she can't remember anything, thank god everything was okay now.

"Well, err... aren't you going to the kitchen, mom?" you lied as you didn't tell her everything.

"Oh yeah, I remember, thank you, dear." your mom responded as she headed to the house. You really glad that's over, but the ray-gun wasn't in your hand anymore. You turn back as you see your girlfriend holding the ray-gun in her hand. "So, this is a ray-gun that you working on, huh?" She asked as she looks at you suspiciously. "Is this why you test it on your mom?"

"Look, I'm sorry, okay, I was try to test it to see how it works." you explained to your girlfriend.

"Well, it worked alright. But as for your mom kiss you..." she said as she controls her anger.

"That was an accident, I'm so sorry. You can punish me whatever you want, I guess I deserved it." you replied sadly. But then your girlfriend hold your face and kiss you deeply.

"Okay, I won't be angry now." your girlfriend broke the kiss as she talks to you. "BTW, how does this thing works anyway?"

After a few minutes, you instruct her to use the gun and show her everything you just did. "Well, that's kinda easy, but okay." your girlfriend said as she know how to use it.
