Her mostly naked body was just in front of him with her long red hair covering her perky double D breasts.  He could not help but look and stare, he tried to hide but she noticed.  Catherine looked hard at Timothy, then she noticed his pants with a small bulge, she smiled.  Catherine moved her hair behind her head with her fingers while slowly walking towards Timothy.  “Oh my, oh my what do we have here?”  She dragged Timothy by the hand into the locker room just as the other girls noticed him.  Timothy was now standing in the middle of the locker room blushing as all the girls gathered around him.  Before Timothy could run Amber lowered her hands down his pants as Claire unzipped them. Amber took her other hand and slid off her bra.    
Catherine was looking through her backpack, “I know its here, it must be here”.  “Caroline have you seen my phone?”.  Six foot, Three inch Caroline poked head out of the shower, “its in the locker”, she then noticed her brother Timothy just standing there with Amber and Claire undressing him in front of the entire grade 12 swim team.  “Timothy you pervert get out of here”.  Catherine looked at Caroline and replied “No no no ...we want to have little fun, plus he has already seen us naked so whats the harm in us getting something out of it”.    
Caroline stepped out of the shower naked drying her hair and was just standing.  “Fine as long as my mother doesn’t find out,  Timmy you wont tell mommy about this right?”.  Timothy nodded as all the other girls removed their clothing and tossing their panties at him.  Some of the silky and lace thong landing on Timothy’s now erect manhood.   Amber went down on her knees and started kissing his balls ever so softly.  Before Timothy noticed one of the girl had used a towel to tie him to the bench.  Timothy was soon forced to lay down on the bench as Kimberly used her tights to tie his legs down together.  Timothy was scared by all the attention.  One of the girls was whispering something to Claire and Catherine. They both nodded.   
Catherine grabbed a wooden ruler from her backpack and held it to Timothy’s manhood. “Wow I did not think they came that small”.  Caroline looked and laughed “Timmy I have a bigger cock then you and I am a girl, is this as big as it gets?”. Timothy embarrassed nodded.  “No matter we can fix that.”  Caroline grabbed her phone and something that looked like a ring from her backpack.  “I was going to use this with Alex later but I figure I should test it out now”.  Amber grabbed the ring like device from Caroline and placed it at the base of Timothy’s cock and moving his balls through the bottom of the ring.  Catherine grabbed Caroline’s phone from her.  
Timothy looks nervous, with good reason.  All the girls had a evil grin, some of them started touching themselves.  Timothy’s cock started to throb and get larger and larger.  “Catherine do not raise the dial on the app so fast you don’t know how his cock will react”.  “Caroline relax it must be safe otherwise they would not sell it online”.  Amber took the ruler out again “2 inches by 1/2 inch, better”, “We are at 30% should we keep going higher?” All the girls nodded.  Timothy’s cock throbbed harder and grew more, he looked shocked as he had never seen a cock that big, not even in the porn movies he watched.  “55%, what are at?”, “9 inches by 2 inches, I think that is enough for me”.  
Amber leaned over Timothy’s bulging cock and started licking the top of the head,  she wrapped her lips around Timothy’s manhood.  “Amber careful don’t get him too close”.  Amber proceeded to go up and down a few times almost gagging along the way.  Amber stopped and moved her pussy onto Timothy’s cock.  Amber rod it for a few minutes as Timothy started to moan.  Amber stopped and moved over just in time to see Timothy spurt his load.  Kimberly came up and started licking Timothy’s cum off his cock and balls.  Kimberly then grabbed Caroline’s phone and turned up the dial on the app.    
Timothy’s cock did not go limp instead it throbbed harder and harder.  Timothy’s face looked like he was in pain.  “You enjoying all the attention aren’t you little brother?”  Timothy winced but could not bring himself not to nod.   
Kimberly accidentally bit down on one of Timothy’s balls.  He cried out in pain.  Abby took her panties off the floor and put them in a ball and gagged Timothy’s mouth. “I am next” she said.  “First we measure, what is the app at Kim?” ”75% and 16 inches by 4 inches”, Kimberly then started to ride Timothy’s cock.  It barely fit inside her super wet pussy.  Timothy looked up and Kimberly and her golden brown hair and her C cup bouncing.  He enjoyed it so much he was getting close again.   Kimberly cam, she got off Timothy’s cock just in time for him to spurt again.  Abby grabbed Caroline’s phone, turned to all the girls and said “who wants to see 100%?”.  All the girls except Caroline nodded, Caroline turned to them “Remember we can not do anything that will leave any marks or be permanent”.  “Abby go up slowly please”.  “Sorry Caroline too late”.  Abby bent down and and licked all the cum off.  “Time to measure this big boy”.  “24 inches by 5 inches, now aren’t you happy you came in here? You have a manhood you can be proud of and you get to have sex with all of us”.  Abby moved her self onto Timothy’s cock.  Abby could not fit all of the cock on her tiny frame.  She rod it until she came but forgot to stop and came 3 more times.  Timothy’s cock did not go soft as he winced more and more in pain.  He did not cum after Abby even though he has a crush on her, he did not have it in him anymore.  
Catherine took the phone from Abby, “My turn”.  Abby got off begrudgingly.  As Catherine took her position she noticed the phone app moved up to 105% and a warning showed up below the dial, exceeding 100% is not advisable as it has not fully tested” but no one paid attention.  Catherine went up and down so smoothly as Timothy’s cock throbbed more and more.  It grew inside Catherine and she was taken a back when it happened just as she came.  Catherine was still holding the phone when she looked at the display and it read 125%. “Shit that is not good”, Caroline looked at the display as Catherine got off.  All of a sudden Timothy started to cry as he came so hard it touched the ceiling.  The girls looked impressed.  Claire raised her hand “my turn”.  Claire tried to wrap both her hands around Timothy’s cock, that by this time looked like a a small tree trunk.  “Can we slow down please” Caroline pleaded.  Timothy started to weep hard so Claire started to try and put his massive cock into her little pussy.  She was standing up at her full 5 foot 8 inch, she could only get the top of the head in while on her tippet-toes the other girls helped her on.  She came two times in just minutes.  Claire got off and noticed that while she was cumming blood started to stream down Timothy’s throbbing cock.    
“Claire is this your first time?”, “No I have had sex before but never with anything this big”,  Kimberly grabbed the ruler. “Wow its more then 36 inches by 6 inches.”  Claire got off,  “the blood is not mine, it was coming from Timothy’s cock head.  It was spurting blood through the hole.  Caroline quickly grabbed a maxi pad from " her purse and wrapped the top of her brothers penis with her panties with the pad inside.  
“What can we do now? He is bleeding”.  Catherine looked at the app on the phone, somehow it climbed to 200%.  Catherine quickly turned the dial down ... but the number kept climbing. “This is not good ... 250% ....” . Timothy was looking at his cock as it got larger and larger. “300%, lets reboot the phone,”. Caroline panicked and pressed the power button to force off the phone.  Timothy’s cock stopped bleeding, they removed the gag from his mouth. “It hurts so much ... make it stop” Timothy pleaded.   His cock grew more and more. It was no longer able to be upright and he started to look flush.  All of his blood was now rushing to his manhood.  The girls started to freak out.  Timothy tried to reach for the ring like device at the base of his cock, “remove it please”. Amber reached down and tried to open the ring, meanwhile Caroline’s phone finished the restart and they launched the app.  The screen read “Synchronization in progress.”,  suddenly Timothy’s cock twitched very very hard.  His cock now so big Caroline’s panties barely fit on the head.  All of the girls watched as Timothy’s cock got so thick that it popped the ring device off.   The app display read “unable to communicate with ring, synchronization failed”.  The app then exited.  Timothy’s cock started to shrink and go soft, everyone in the room breathed a sigh,  “Timmy it looks like you will be okay just promise not to tell mom I did this”, Timothy nodded that he never wanted to speak of this again.  As a show of good faith all the girls let him keep their panties, even Caroline.    
After 30 minutes Timothy’s manhood had gone down to a normal average size and he started to get dressed again... he put on all the panties under his pants so he could sneak them out.    
All the girls got dressed in front of Timothy, with no underwear under their uniform kilt, they hoped that no teachers noticed.    
Days later Timothy walked in to Caroline’s bedroom. “I want to thank you for what you did” he said.  She lay down on her bed removed her panties from under her school uniform kilt.  “Well I was the only one that did not get a ride or came from it,  close and lock the door .... I want you to lick clean my pussy until I come.”  Timothy complied.  He lay down put Caroline’s kilt over his head and went to town.  As Caroline got close and moaned with pleasure Timothy’s cock started to throb.  Timothy excused himself while he removed his cock from his pants, he was hard again but this time he was 12 inches. “Timmy come here”, Caroline put his head down between her legs again .... he licked her hard and fast, she arched her back and came with her pussy juice all over his face he looked up and got her to come a second and third time.  Meanwhile he got close it started to hurt.  Caroline decided to be nice and put her lips around his amazing cock.  “Timmy come into this”, Caroline held up a metal specimen cup just as Timothy’s cock exploded with cum, right into the cup.  Caroline was pleased and closed the cup.  Timothy went into Caroline’s bathroom to wipe his face and his cock.  His cock was still hard so he decided to strip and stepped into the shower and rub it off.  Caroline walked in and watched him rub it so hard she decided to help, she stripped down and stepped into the shower.  Caroline knelled down and put her breasts around his rock hard cock and licked the head with the tip of her tongue.   
All of a sudden Timothy came again but this time it felt a little different, he looked down and noticed  his cock was no longer between his legs just his balls.  Caroline still had his cock between her breasts and part in her mouth.  She then noticed him step back. “Whats wrong don’t you like it?”, then the noticed. Blood was oozing down from between his leg.  Caroline freaked out, stepped out of the shower and grabbed a super flow tampon from the vanity and inserted the tampon into the hole where Timothy’s cock used to be.  The bleeding was subsided because of the tampon.  Caroline ran outside to call her friend Amber who had first aid training.  Amber came over right away and went directly into the shower where Timothy was changing out the third tampon.  Amber grabbed a suture kit from her pocket.  She looked at what was left of Timothy’s cock, it was black and dead. “I am sorry Timothy it can not be reattached, it has been too long”.  Timothy looked at his cock and started to cry.  Amber quickly changed gears, “let me close up that wound so you do not bleed to death, maybe we can make lemonade from this lemon”.  She started to clean the wound and shave the hair away to keep the area clean.  Amber carefully used Caroline’s electric shaver to remove all the hair.  Timothy was laying down on the floor and could not bring himself to look down and see what Amber was doing.  “All done, I have done what I can do”.  Timothy looked down to see he now was smooth above his ball sack the hole was closed and he was no longer bleeding. “How am I going to pee? I have nothing down there”.  Amber replied “don’t worry Caroline and I don't have a penis and we pee just fine, she smirked”. Caroline peaked in and showed her brother with a makeup mirror his urinary tracked was now a hole just below his balls.  Amber put some bandages over the area to help the suture hold together.  
Amber admired her work and could not help but taking photos.  
Caroline gave Timothy a pair of her period panties with a pad at the bottom.  Timothy started to cry again. “Don’t worry Timmy your baby batter is safe in the specimen cup.  I put it in to the deep freeze downstairs in the basement.  Mommy never looks their since Daddy put the deer inside.  It will be safe until we find a better plan”.  
“You still have your balls, so you can produce more” Amber added.  
Timothy stood up and went to his room.  
Caroline thanked Amber for her help and walked her to the door.   They both could hear Timothy still sulking.  “He will be fine in a few days, give him days, but I may have sutured the blood supply from his scrotum,  he may lose his balls in a few days, dont worry it will then all look like a pussy with a clit”.  
It took Timothy a few days to get use to his new peeing method, but he did.  In the middle of the night he pulled down his pants and his new briefs and sat down.  He was half asleep until he noticed a little blood on the front of his underwear approximately where his ball sack is, he thought nothing of it until he leaned over to wipe.  Something felt different, he stood up half asleep pulled up his underwear and pants. He looked into the toilet just as he flushed, that is went he noticed his scrotum floating on top of the water and underneath his testicles starting to go down the drain.  He stopped flushing too late and the last of his manhood went down, and was lost forever.   Timothy crying walked into his sisters room and climbed into bed with her.  “What the Hell do you think you are doing” Caroline yelled.  Timothy pulled down his pants and showed her.  “Well so long and good ridden” Caroline responded, “Now go back to your bed”.    
The following day in school Caroline was talking to her boyfriend Alex as she noticed her brother walking around wearing a kilt and white panties.  She ran over to him and dragged him into the girls locker room.  “What the Hell do you think you are doing Timothy?”,  Timothy  showed his sister again, “Amber shaped it into a pussy for me this morning”.  Caroline was worried what her mother will say, Timothy calmed her down by saying her mother knows and its their mothers panties he is wearing and a spare kilt.    
That evening when Caroline came home her mother was walking around naked with Timothy.  “Caroline, Thank you I have wanted to do this to your brother since your father left, now we are free to walk around naked and not worry about your brother, from now on he will be known as Theresa”.  
Theresa did not seem happy with her fate, but eventually got used to it and grew breasts.  Then one day Caroline called Theresa into her room were Alex was on the bed naked with the ring like device around the base of his cock.  “Theresa you want to help me control the app?”,  Theresa ran out of the room crying just as her mother walked in to help Caroline.
