Jasmine was wearing a really tight pencil skirt that came all the way down to her calf but mercifully had a slit all the way up to her mid thigh making it easier to walk with her two massive horsecocks barely concealed between her legs, if she walked too fast her cocks would swing and bulge out against the fabric. She was also wearing a tight top and no bra and her tits nearly popped out of the shirt of she wasn't careful. Jasmine was really starting to regret wearing her sister's clothes as she sat on the bus to school.
As she sat alone near the back and the bus bounced over the horrible roads her cocks started to get hard and grew right out from under her skirt and under the seat in front of her reaching almost 3ft before being spotted by a really cute freshman girl named Mary. Mary was a small 5' nothing brunette with a large 34 E bust and tight athletic body and a fellow cheer member and she gasped as she looked across the isle to she the huge horsecock laying on the floor following it back to Jasmine who was looking out the window unaware. She smiled to herself as she saw it start to retract and was planning on cornering Jasmine during cheer later this morning.
After arriving at school Jasmine headed to the locker room and changed for cheer after banishing her cocks and had no problems until after cheer. She heard the shower running long after she thought everyone had left and went to go turn it off thinking someone had left it running but as she got closer she could hear a girl making noises as if she was masturbating. Not wanting to be seen she snuck over and looked to see who it was and was shocked to find the hot freshman Mary standing in the shower and further shocked to see her stroking a massive 5ft cock that was almost peeing pre as Mary stroked the cock that seemed to be growing even longer as she watched! Jasmine had already returned her 17 inch horsecocks from the morning and grew them even longer letting them reach 3ft while soft and then start to let them grow hard as she watched Mary stroke her indeed growing cock. As Jasmine's cocks grew longer and longer she also started to produce pre and her balls worked overtime to make more cum as her cocks grew surpassing her 7ft cock from the morning and reaching an insane 13' 2" as huge ropes of pre lasting almost 20 seconds shot from her cock and splattered on the floor, the noise hidden by the shower, creating a huge puddle. Jasmine looked back at Mary to see that she had grown a lot in the time she had gotten hard being almost 8ft and still getting larger as her cock poured forth a never ending stream of pre as Mary moaned as she stroked her massive member. Finally Jasmine stepped out and revealed herself and her massive horsecocks making Mary gasp "Holy shit! Those things are huge!" She said as Jasmine's never ending cocks came into view.
"Your not bad yourself but you keep growing, aren't you hard yet?"
"Uh yeah I actually have a 15 inch cock fully hard but it grows non-stop until I cum. So give me a bit and I can be even bigger than you!"
"Wow but my load will dwarf yours if this morning was anything to judge by."
"Challenge accepted!"
And with that she reached out and stuffed one of Jasmine's cocks into her mouth. Jasmine watched the massive bulge of her cock stretch Mary's throat then bulge out her stomach as she sucked down 4ft of Jasmine's cock. Jasmine responded by doing like wise to Mary's growing member. Both girls quickly started to get rounded and inflating bellys as the massive amounts of pre produced by both was caught in each others stomach's. Jasmine's remaining cock was jerked by both girls as huge streams of pre worked to fill the shower with its many drains and was failing so far. As Jasmine's first cock inside Mary's mouth neared orgasm she yelled "Fuck I'm gunna cum!" And her cock unloaded into Mary's already massive belly making it swell to look like she had swallowed a massive pumpkin. Mary was forced to pull off even before the first stream was finished and was blasted full in the face with Jasmine's seed. The first shot lasted a full minute before shooting 45 second long streams for almost an hour. As her first cock came Jasmine's second cock started to cum a few minutes after her first and she moaned in increased pleasure as this cock jerked in her hands and shot one huge stream of cum for 40 minutes. Both cocks filled the shower room to waist height in cum as the drains worked to clear the mess. As Jasmine came down from her orgasms she looked over at Mary who had jerked furiously the whole time watching the display and her cock was huge! It jutted out from her small body 25ft long reaching across the locker room and filling the rest of the room with her pre. "Fuck! Watch this!" She said as she finally came herself. She shot one continuous stream of cum that varied in strength as her massive cock flexed to push out her huge load. Mary only came for 15 minutes but her load was more than twice the size of both of Jasmine's cocks and filled the locker room and flooded the gym to waist height in girl cum. As Mary went soft her cock returning to a small 4 inches she smiled at Jasmine "That was fun! We should meet after school sometime." Then as both girls were outside after Mary's huge load had forced them out of the locker room she turn and walked to her car just as school was cancelled to to a surprise flood in the gym.
