Amanda finished the vial.20 minutes nothing happened. Justin started to examine her body to see if anything changes in the future. Amanda said she weighs about 109 pounds and is 5’1.Justin noticed Amanda had little too no definition in her arms or legs and no breast or butt.

After Justin was done writing Down his observations he asked Amanda to do the same. Amanda started to study Justin’s body. Justin said he was about 110 pounds and was 5’2.5. Amanda began to notice how little muscle Justin had. Amanda noted that he couldn’t have been much stronger than her because his arms were the same size if not smaller.

Amanda wanted to test his strength so she challenged Justin to a arm wrestle. Justin said yes. Justin and Amanda agreed to do the arm wrestling match in the transgender bathroom. First Amanda and then Justin asked to go to the bathroom.

Justin and Amanda squeezed into the 1 person bathroom and put both they’re arms on the bathroom vanity, Justin and Amanda counted 1,2,3 go

Amanda and Justin were pushing with all there might but neither were going anywhere but slowly and surely Amanda was pushing Justin closer and closer to The ground. Justin was astonishing at how Amanda was overpowering him could it be that the enhancer was working but it wasn’t changing how she appeared. Amanda was running out of gas she was pushing so hard and was so close,yet she couldn’t finish him off. Justin noticed that Amanda started to look fatigued and with this new information he had a sudden burst of strength and was pushed Amanda back the starting point. Amanda felt like it was over she had nothing left .Justin then pushed Amandas arm easily to the ground.

Justin started to talk some smack but he couldn’t help but notice how much weaker he was than he thought.

By the time Amanda and Justin arrived back at class There was only 5 minutes left. Justin quickly gulped down the vile of red enhancer in his bag.

The bell soon rang and Amanda and Justin went on there bus rides home.

Amanda arrived home. Amanda had the entire house to herself, Amandas parents are both in Florida for the whole week on a Bussiness trip. Amanda ran to the fridge and grabbed as much food as she could. The serum seemed to make Amanda really hungry. In no time Amanda ate everything in the fridge and must have eaten 200000 calories in 30 minutes. Amanda was full, she couldn’t eat anymore. Amanda walked over to the weight room ready to turn calories to muscle.

Amanda continuously worked out for the next 3 hours.

Meanwhile at Justin’s.

Honey hurry up we’re going to swimming and gymnastics practices yelled Justin mom to Justin’s 14 year old sister tanya. Justin was in his room pouring his red serum into a cup so he could pour it in h The sink because all serums go bad within 48hours and he had 5 hours left. Justin walked down the stairs to the kitchen leaving the cup of serum on the counter for no longer than 30 seconds. When Justin went to pour the cup into the sink it was gone ?

No one was home and his moms car was just leaving to bring his sister Tanya to practice. Tanya must have took the cup of serum because she could find anything else. Justin panicked but they’re was nothing he could do so he opted to do exercise in his room tell his sister comes back.

4 hours later 10:30

Tanya arrived home and ran to the cupboard for a “snack” Tanya ate somewhere between 50000- 100000 calories in 45 minutes.

2 hours later 12:30

Once everyone in Justin house fell asleep he snuck down stairs to take some notes on his sister who was sleeping on the couch.

Tanya was 5’1 115 pounds She has little to no breast but she is quite curvy and much more defined than Amanda and Justin she had the body of an athlete. )After taking these observations Justin went to sleep

The next day 7:30

Justin woke up and was ready to get dressed but something was off. He looked in his mirror and saw a totally new body sure he wasn’t buff or anything but now he’s arms,legs,hands and even his bulge grew by at least 2 inches. His once loose sleeves were now much more full and He had the beginnings of a six pack. He weighed himself and measured his height he was now 5’4 and 126 pounds. After putting on his clothes he walked down stairs.

Once Justin was down stairs he pour himself a bowl of cereal. Two mins later and Tanya woke up and sat down but Justin couldn’t help but notice how heavy that sounded. Five more minutes passed and his mom woke up. When Justin’s mom woke up she couldn’t help but notice how much different her kids looked. She said go back to back to measure there height.

Justin didn’t feel good about this was she gonna be taller ? Finally justin and Tanya went back to back and they were the same height. Tanya couldn’t help but be excited her a 14 year old was the same height as her 16 year old brother of course she teased him for this saying “ soon I’ll be taller and I’m already stronger” Justin was very intimidating. Tanya has no time for a strength competition and she’s went in the shower.

Tanya finally got out of the shower and went in her room to change. She looked in her bedroom mirror at her new body and was amazed. Her perviously almost nonexistent A cup boobs were now DD cup and her ass was huge she looked like a 25 year old supermodel but the most unexpected thing she noticed was that she now had a six pack and big arms and her thighs were so defined it unbelievable. Tanya finally put on an outfit of Short skirt and a push up bra she found in her moms room And Small Tight shirt. She walked out the back dood so her mom wouldn’t notice and walked towards the bus. Tanya and Justin walked to the bus but Justin couldn’t help but notice that Tanya was at least 5’4 and 150 pounds ,Her thighs were big and muscular like a running back and her arms were bigger and more muscular than his.

Finally the bus arrived and Justin and Tanya got on. Tanya and Justin walked down they’re seats but right before they were about to sit down a boy heckled in the back. “Hey what’s you’re name baby girl, you should come back here and sit with me”; it was a popular senior named John. Tanya was memorized she could believe a senior was talking to her. She was a freshman after all. Tanya began to walk towards John in the back of the bus. She couldn’t remember what John looked like but she did remember that all her friends thought he was handsome. Tanya finally was in the back and she saw John, John was very skinny he kinda looked like a noodle with pretty nice face.

John : “come sit right her” points to the seat. Tanya: Tanya: okay sure. Tanya sits down next to John. John could feel her massive ass plop down on The seat and her thicc thighs rubbing against his his very thin ones. “What’s you’re name I’m John are you new here asked John” “my names Tanya I’m a freshman so kinda”. John was stunned, “you’re a freshman damn you look my age if not older, soooooo you wanna come to my house later ?” Tanya moved closer to him putting his hand on her thigh. He grabbed her thigh and was astonished by how muscular it was. He was already very aroused previously from just sitting next to her thicc thighs but after grabbing them with his hands he had a raging boner. Tanya began to notice how aroused he was from just grasping her thighs, Tanya started to flex her leg muscles johns hand went loose because he wasn’t strong enough to push down the muscles. Tanya pushed his body against the window and his face into her chest with little resistance. Tanya looked down to his crotch and grabbed his penis then she whispered in his ear “ meet me after school well walk to you're house by the way I’m a virgin don’t tell anyone or it’s off”. The bus stopped Tanya got up and walked down the Aisle to the down of the bus. John was left in the back of the bus with jizz in his underwear.

Meanwhile Amanda had just woke up she didn’t have to be at school tell 2nd period. Amanda got out of bed and walked into the bathroom. She looked in the mirror she was completely naked. She looked like a new woman her arms had grown to twice the size and her thighs were much firmer and thicker. Amanda was clearly taller and heavier she went on the scale to check how much ? She was 135 pounds and 5’5 after weighing and measuring herself she went in the shower. While in the shower Amanda couldn’t help but play were her new body. First Amanda played with her fat ass, twerking it, slapping it and using her ass cheeks to turn the shower off and on. Amanda then played with new boobs previously Amanda had very little of them. When Amanda ran around outside her boobs never jiggled but now Amanda had perky d cup breasts that jiggled every time she moved in the shower. Amanda got out of the shower and walked into her room to get dressed but nothing fits anymore so Amanda put on her moms spandex work out and shorts and a tight t shirt and went do stairs for a work out. 30 mins later Amanda walked to school to her second period class.

Amanda, Justin and Tanya had all arrived at they’re second period classes . It was tanya’s 2nd day of freshman year after being sick for the last week. When she was walked into class all the kids starred at her and the teacher was surprised a freshman could even look like that.

They’re was one boy in particular he was very skinny and short. Tanya wanted to test out her new new body so she gave him a glance and winked at him.
