This is fun, but it’s getting pretty late. Besides, you’re starting to get a little bored, and maybe it’s time to recharge a bit and come up with some better ideas. The world is your oyster, and you can go at your own pace. You shrink yourself down from a building-sized giant to only a couple of inches tall, switch the gun to "transform," change yourself into an entirely different-looking man, and enlarge yourself to about six foot two. You then seek out a bar to sit down and maybe meet some chicks.
You've underestimated the extent to which the world has changed since last you tried passing off as a normal human being. You walk to your favorite bar, Puzzles over on 8th, and stroll in to find everyone staring at you in slack-jawed silence. They're mostly cowering under tables and in corners. Can they see through your new face? Then you realize: they're just shocked to see anyone crazy enough to walk the streets at all after the giant's rampage. You shake your head a bit. "No one's seen him in about ten minutes," you say. You wouldn't want to say it's safe out there; a regular person wouldn't know that. "Some people are running around."
Unfortunately, people start asking you where you've been. You claim you were holed up in a corner of the park, hiding under some benches, and the giant walked right by you, close enough that the footfall nearly blew you over. That sounds realistic, and sure enough people seem to buy it. By the time you're done with the story, you see some people buying beers at the bar. "Hey, don't cut me out of that," you say with a smile. "I went through a lot to get here. Could I get a Jack and coke?"
Drink in hand (making sure to tip your bartender handily), you turn and face away from the bar. A gorgeous brunette is staring at you. She's about 5'8" and cute, with a skinny body yet really nice breasts. "I can't believe you actually went walking around like that," she says. "That takes some balls."
"Well," you start, and then you don't continue. There's nothing else to say. You see a table in the corner, dimly lit, and you have an idea. "Let's have a seat," you say.
You sit down and look at the girl again, and she stares back, fascinated and otherwise expressionless. She opens her mouth to speak, then pauses for half a second. "What was it like?" she says.
"What do you mean?" you ask, nonchalant.
"Seeing a giant, in front of you," she says. "I don't know if I could handle it. It sounds so ... exciting." You continue staring, and she continues talking, as if she needs to explain herself. "It's just ... it's just completely different. I mean, I know it's so dangerous. We're probably not even safe right now. But I still ... I kind of wish I had seen him."
You smile at her for the first time. "I wasn't in the park," you say.
"What?" She's confused.
You pull out the gun, and show it to her. "This switch transforms you into whatever you're thinking of. This one shrinks you." You pause for effect. "And this one makes you bigger."
You look at her, and her eyes grow wide. Her jaw drops. "No." That's all she can say.
You smile a wry grin. "Are you free tomorrow?"

You and this new girl, Lauren, decide to go back to her place, since you figure the giant has long since been identified and your dorm is probably surrounded by now. You wait a couple of hours at the bar so you can leave without looking too suspicious, and the two of you tear each other's clothes off almost as soon as you walk in the door. She's got an amazing body and you two go at it hard and fast. You come sooner than you'd like, but she comes pretty hard herself. You kiss her deeply on the lips as you climb off her. "See, next time I can transform myself to last as long as you'd like," you say with a smile. She looks at you and smiles, and you pull out the gun. Transforming yourself exactly as promised -- well, with an extra inch of length -- you two go at it again, and again, and again. She gets sore after a while, but then you transform her too, and by the end of the night you two have transformed each other over and over to the limits of your sexual imaginations, and you've each come dozens of times. You've long since lost count. You both fall asleep from exhaustion, in each other's arms.
You wake up at about two o'clock the next afternoon.
