"Fine!" Tiff sighed. "Ready when you're ready."
Katie stood up in the toilet stall and tried to push her member down, which only made it harder and spasm under her touch. There was no way she would be able to pull her skirt over this!
"What are you waiting for Katie? Let's go!" Tiff yelled through the door impatiently.
"Y-yeah! Just a minute!" Katie answered, her 9 inches rod throbbing in her hands.
After some pulling and tugging, she found her erection was much more cooperative if she would guide it under her waistband and inside her shirt rather than trying to keep it down. She then took her bag and hugged it in front of her, keeping her new addition sandwiched under her shirt. She exited the stall.
"Just go, Tiff! I'm right behind."
The two girls quickly left the school and walked to Katie's house. Each step Katie took elicited pleasurable tingles in her dick as it rubbed inside her shirt, tucked against her belly and her bag, which was only making the situation worse. She could tell fluids were oozing from the tip, making her breathe heavily.
"Come on Katie, we're almost there! Don't slow down! You really need to exercize more..." Tiff let out, not even looking.
Katie pressed on, her vision getting a little blurry from the effort. It was taking all of her willpower to not just stop dead in her track. Just as she was taking a deep breath to calm herself, her foot hit something on the curb and she fell forward, faceplanting. Her bag absorbed most of the impact fortunately, but her dick rammed into it and got squeezed under her own weight and against her wet belly.
The intense rubbing pushed Katie over the edge and she felt her inside tightening as a burst of fluids exploded under her breasts, soaking through her shirt. She clenched her teeth to stiffle a moan when the strong orgasm hit her. Her hips bucked against the bag as she lost control of herself for a second.
As she slowly sat on her knees, she brought the bag back in front of her to hide the wet, translucent fabric of her shirt that was now stuck to her body, and outlining her softening member.
"Are you okay Katie?" Tiff asked as she turned around. Katie was still out of breathe, trying to process what had just happened.
"Y-yeah! Tripped over something, that's all!" she replied in an uneasy voice. The thing between her legs was shifting around under her clothes, shrinking down back to her panties and retracting inside her body, Katie realized. After this short pause, she stood up and the girls resumed walking.
Katie still felt sort of funny between her legs, and a little weak on her knees from the afterglow. Quickly enough though the girls reached her house, and Tiff turned around to face her. Katie hugged her bag a little tighter over the moist front of her shirt.
"Thanks for walking me home, Tiff! I'll explain everything eventually, but now is just not the right time! And please ditch the fruits you brought back from that weird place, you don't want to get into trouble."
Tiff nodded, unconvinced, and waved her friend goodbye before heading back to school.
Katie entered her home and dropped her bag immediately as she was closing the door. Her shirt was drenched in thick fluids that had smeared all over her belly and under her small chest. Pulling down on the skirt though, the penis was gone... although her clit protruded outward a little, visibly thicker than it used to be.
She reached down with a trembling hand and tugged on it, but nothing happened. Maybe the release had fixed her problem, she thought with relief...
