Maybe the gun has any clues on it?

You wipe your face clean as Steve steps over to Andrea and lets her suck his dick clean. "Thanks for sharing," he tells your sister as he zips up his fly and pats her on her head before handing over a roll of cash. About three hundred dollars worth if you were to guess from the size of the fat wad of green.

"You're welcome!" Andrea smiles happily but with a hint of weariness, not doing anything to keep the conversation going. Steve picks up on this and moves towards the exit.

"I'll see you two around, yeah?"

"Sure," you smile happily towards him as you rise up from your knees and pull the top over your tits again. His fluids are still rolling through your mouth and evaporating off your skin. A well paid blowjob is always more rewarding than a free one. And even if you like what Steve can offer, you think finally not having him as your ever-present roommate is a blessing your former self would have enjoyed.

'Oh right,' you think to yourself as Steve shuts the door behind him. That was a thing you probably should wonder about... how you became Mary, Andrea's slutty sister and roomie. That gun that you used on Andrea ten minutes ago might have some clues.

"If I knew Steve had money and blue balls, I would have called him over for some fun earlier," Andrea sighed as she split the wad of cash and gave you fifteen tenners. "Still, we know how to make our own fun, don't we sis?"

"Sure do," you giggle and think back at the little sixty nine minge binge you were getting into before Steve arrived. Your body was still elated from the orgasm that she managed to coax out of your girlhood. Some part of you remember a blowjob that was very appreciated as well, but it feels weird to you right now to have been the one receiving it. "World shattering fun," you say, causing your sister to glance at you with confusion. Some part of you wants to delve into it, but you keep it under control and wave a dismissive hand at it.

"Mind if I shower first? I assume you're off paying rent again since you're just using wipes?" you ask your sister.

"Wolovitch thinks my pussy is the one ring for some reason," Andrea sighs. You giggle at the reference, wet dream memories of Legolas and Gimli spit-roasting you flashing through your head. "twice in a day. He must be working out... Or his wife is out of town for a day or two. I'd love to see how he'd react if I let him become a daddy again... or how she'd react," she adds and you both giggle at the thought.

"Have you seen his kids?" you add as you move over to the coffee table with the drawer you left the gun in. It has fundamentally changed like the rest of the apartment, but it's located at the right spot. "They're not cute."

"Yeah, he would need to be a lot richer for me to consider that," Andrea sighed and gazed off in the distance, momentarily daydreaming.

You took the moment to open the drawer. The gun was still there! You pick it up delicately and cover it with the bag of wet tissues held in the same hand, some part of you afraid that stuffing it into your pocket might cause it to fire again. "See you later," you say over you shoulder as you move towards the bathroom, Andrea waving a hand as she picks up her phone and starts answering some messages.

You close the bathroom door and look at the gun. There's about a dozen small lights on the side of it, four red, four orange and four green. It's down to three green right now, but you notice it rises and lowers as you move towards or away from the door. Seems like it's measuring the power levels of something, peaking like a sound bar.

You watch the lights for a minute and see it becoming less and less agitated. You leave it on the sink counter as you undress and tip-toe into the shower, washing off the cum and rubbing yourself down. You wrap yourself in a towel as you finish your shower and look at the gun. The lights have all died down.

What were you going to do again with it, though?
