Jen had quickly and quietly gotten on the bus,doing her best to keep her cock tucked deep down into her sweat pants. Her panties felt so tight against the massive member, and Jen was afraid she would tear these ones apart as well. She sat near the front, away from everyone else and just stared at the seat ahead of here, trying to ignore the lingering and growing lust in her crotch. The bus moved along its route, picking up several other students who just added to the background noise Jen was ignoring.
It wasnt super long before Jen's friend Katie plopped down beside her, wearing a slutty short skirt and tight top. "Hey Jen" the red head said, turning slightly towards Jen to talk. Jen's eyes travlled from the seat in front of her to her friends smooth, light, exposed legs and up her body to her now inticing looking C cup breasts. "H-hey Katie." Jen managed. Her crotch stirred as her cock began to awaken once more. Jen moved her hands over her pants to hide the shifting bulge. "Cold huh? I hope you brought your cheer outfit for later at least. We get to cheer for everyone at the football game after school! Im so excited!"
Fear rose even more in Jen. The football game would mean she'd be in front of everyone with this thing. Her cock slipped from her panties and began to inch down one of her pant legs. Jen kept moving her arms to try and keep Katie from noticing. Despite her best efforts, it kept growing, going down past her knee and starting to dripple precum. Her horse pussy began to moisten as her balls churned. Bitting the inside of her lip to keep quiet, Jen 'mhmmm'd in agreance with Katie. She kept looking over at her, her hot body, her tits and...
"Oh!" Jen jumped a little as she came just a little, the thick cream leaking out of her pant leg. She came just from thinking too much about Katie?! "What Jen?" Katie asked. Jen murmured a response and bent over to try and hide the cum on the floor. Jen discreetly also tucked her cock behind her leg to keep it from hardening further and tenting her pants. She pushed as much of her cum as she could under the seats and hoped no one would notice. As Jen sat back up, she accidentally grazed Katie's leg with a partially cum covered hand.
"Hey wa-aaaAahhah!" Katie trailed off as Jen gasped. Katie began arching her back and grabbing at her chest and rubbing her crotch. Jen couldnt take it and her cock immediately shot out the end of her pants and into view of everyone. Katie's new cock burst through her panties as well, popping out of her skirt with her balls resting on the seat. Katie moaned like a bitch in heat as she eagerly touched her brand new cock. Jen stroked hers watching, unable to help herself. Katie came in second, fountaining cum over the bus. Jen started to cum shortly after, amazingly turned on from seeing her friend like this.
All the girls on the bus started to moan as the few boys looked around in shock. Shortly after various sized and coloured horse cocks wagged above seats, filling the bus with more and more hot sticky seed. It was a while before they were done. A trail was left down the road showing the bus driver had pulled over. Cum was up to their knees, and all the girls were panting. Jen and Katie had shared a deep kiss for a while, but it was broken by the bus driver turning around to yell at them. "C'mom girls!" He shouted "Keep your cocks under control please!" Murmuring he turned back and drove onwards to school, with a bus load of cum waiting to burst out like a wave.
