You (Nick) decides to fuck with his best friend, you exit the machines room and go outside where you see Martha Jennings jogging across the street. "Now's my chance" you say as you run across the street to meet her "hey Mrs. Jennings! I was wondering if you would like to participate in an experiment of mine?" She pauses to smile at him before saying, " thanks for the offer, Nick but I gotta finish my jogging laps, maybe next time". "It'll be quick! I promise, please it's for a grade" you finish while she ponders it, "well...okay, if it's for a grade AND if it's going to be quick" she depends as she follows you home into the machine room.
"Ooo, is this your project? It looks cool" she remarks while admiring the machine, "yep sure is, just get in this post here and wait for me for just a second. I'll be quick" she nods as she walks into one of the pods while you drink some water to swallow some sleeping pills, it should keep her busy for a while. "Okay I'm ready" you say as you press the start the machine and get in your pod already getting a little drowsy, "soon what does this thing d-" Martha begins before the machine suddenly starts and begins to swap both of your bodies. It hums and whirs as you are ripped out of your body and are pushed right into Martha's until it finally stops and your pod opens appointing you to step out.
The first thing you notice was how the cool air hits your now very sensitive skin; it sends chills down your spine and makes you shiver slightly. You look at your now feminine arms and how slender they looked, your dainty hands and fingers how much smaller they were compared to your old ones, you watched your new breasts rise and fall with every breath and feel how tight and sweaty your new black hair felt tucked away in a ponytail. You touched your now full lips and felt how soft they were while another hand felt his new thighs and slender legs causing you to bend down, you then noticed your now very plump heart shaped ass and have it a slap watching it jiggle in your new tight yoga clothing. "Hey, maybe harassing Him won't be the only thing I'll be doing as Mrs. Jennings" you say for the first time in your new motherly voice while smiling about your future plans.
Suddenly the other pod opens while saying, "oxygen: depleted. deploying passenger" as it spits out your now unconscious body that was now inhabited by Martha, you smirk as you walk over to your snoring body. "Enjoy your nap, Mrs. Jennings, while I enjoy you" you say as you put one limp arm around your shoulder and hoist your old body up so you could drag him in bed,hopefully avoiding your family. "You make it to your room with no trouble and put her in your bed to sleep bitten your mother springs up and you quickly hide in your closet as she walks into your room where she smiles and tip goes closer to Martha "hehe enjoy, your nap Nicky, I'm just going to play your video games" she whispers just loud enough for you to hear in your hiding spot as he inputs your gaming system and brings it downstairs. After waiting a couple seconds to make sure the coast was clear you open your closet and top goes quickly downstairs and out side your house where you were now home free.
"Alright, time to see how fast this body can run" You say as you sprint back to the Jennings household to enact your plans. Turns out all the jogging she had done prior hasn't caused her any strife as you quickly found out as your new slender legs strides across the pavement until you were standing just outside the Jennings household. "Alright New family, say hello to the new and improved Martha" you say as you pull lighten keys that were deep in your new breasts and unlock the front door so you could step in. As soon as you step in you notice how quiet it is, no one was downstairs at all, "Okay then, let's check upstairs" you says as you jog up the stairs to hear your friend playing on his gaming system and his sister in her room sleeping.
You look down at your very sweaty body and slightly jiggle your goons before...
