Umi slept quietly slumped in her chair. Rena sat at her desk behind Umi and Pup was in the empty seat beside her. They had spent the remainder of lunch watching the students take turns fucking the teacher, not one of whom had been able to make her cum.
Pup turned towards Umi and leaned in to her sleeping face.
"Should we wake her up?" Pup asked as she tapped Umi's nose with her finger. Umi unconsciously turned her head to the side.
"Probably." Rena answered.
"I got this." Pup giggled as she got out of her seat, wrapped her left arm around Umi's neck, and groped her breast. Her other hand slid underneath Umi's skirt.
"Jeez, her balls are so big even after cumming like that!" Pup exclaimed as she dug around. "I want to feel them when their full. Okay, here we go."
Umi twitched as Pup dug two fingers into her pussy.
"Wakey, wakey." Pup cooed into Umi's ear as she played with her nipple and fingered her. Umi moaned quietly in her sleep and Pup picked up the pace, circling and thrusting her fingers as she stirred up Umi's insides.
Umi slowly opened her eyes, feeling warm and comfortable. She unconsciously grinded her hips, unsure why it felt so good. After a moment, she finally snapped to and became aware of her surroundings. She turned to the side and gasped, shocked that she was an inch away from Pup's grinning face.
"Good morning, big girl." Pup slipped her glistening fingers out, wrapped her hand around the base of Umi's cock, and squeezed it. "God damn..."
"S-sorry..." Umi stuttered in her confusion.
"For what?" Pup slowly stroked Umi's flaccid dick. "Hey, we still got a bit of time, think you could get hard for me? Just a quick ride before class, promise I won't try and make you come."
"I... uh..." Umi froze up, unsure what to say or do.
"Alright Pup, your scaring her."
"Oh, right. Sorry, sorry, sorry." Pup pulled away from Umi, sliding her hand up Umi's cock as she did. Her hand reached the head, which was big enough to fill her palm. Umi twitched as Pup massaged her still sensitive glans.
"Pup."
"Okay, yup. Just wanted to feel it real quick." Pup finally let go, and Umi's warm cock flopped across her thigh.
Umi glanced around the room. She was flustered, but calmed down once she realized she was back in the class room. She turned around to see Rena behind her.
"We brought you back after you passed out." Rena said. "Your lunch and your underwear are under the chair."
"I put your skirt back on!" Pup interjected.
Umi's skirt was soggy and wet with cum. She leaned over to see her lunchbox next to her cum soaked panties, cocksock, and ballkini under her chair. She shuttered when she leaned over as her distended stomach reminded her that she still had a womb packed full of cum. She looked back up at Rena and Pup.
"T-thank you." She stuttered.
"You're welcome!" Pup cheerfully exclaimed. She sat for a moment, then slowly reached out with her legs and lifted Umi's thick flaccid cock off her thigh, squishing it between the arches of her bare feet.
"Pup..." Rena glanced at Pup, annoyed.
"I-it's okay..." Umi mumbled. She felt a little uncomfortable being the center of attention, but she was also happy the two went out of their way to help her.
"See, she's warming up to us." Pup said as she stroked and jerked Umi's cock.
Rena looked to Umi, then back to Pup.
"Hm." Rena watched Pup's feet for a moment when a thought occurred to her. "Where are your shoes?"
"I took them off."
"When?"
"When I got here this morning. I put them in my locker. I like being barefoot and the floors here are all super clean."
"Huh, I guess so." Rena said as she glanced down at the floor.
"That, and sometimes I just like to feel warm cum between my toes. Speaking of which, it was fun watching you fuck that girl silly." Pup said to Umi. "That was the biggest load I've ever seen."
Rena nodded in agreement.
"Yeah, I've never seen someone cum that much." Rena looked to the front of the room, where Bahlus was bent over her desk as she was vigorously pounded by a tall lanky girl. "You should go next. I bet you could make her cum."
"Ah, yeah!" Pup gasped. "Do it, do it, do it!"
"I c-can't." Umi said as she shivered from Pup's feet playing with her dick. "I can... only cum once a day."
"Aww, what?"
"Once a day, huh?" Rena said as she stared at Umi's cock. She could feel herself getting aroused at the mere thought of that much cum being pumped inside her. "Taking all that must be pretty intense."
"Ha." Pup laughed. "No kidding."
Umi quivered a bit as Pup's feet teased and stroked her still sensitive cock. Her feet were tough and firm, but still felt quite pleasurable. Unfortunately, having already blown her load for the day, a nice bit of stimulation is all she could get from it.
"Wow, you aren't getting hard at all. Dang. Oh well."
After another minute or so, Pup finally stopped playing with Umi's cock. Umi grabbed her dick, put it back between her legs, and straightened her skirt so it covered down past her knees, hiding her cock. She scooted forward in her chair, spread her legs, then scooted back, and the bulge under her skirt disappeared. Both Rena and Pup were shocked.
"It just disappeared." Pup said.
Rena leaned over from behind.
"How did you do that?" Rena asked.
"It's um... I just..." Umi slowly pulled back the top of her skirt. While her thick cock rested between her thighs, her large balls hung just over the edge of her seat below her legs. With her skirt draped down, it covered everything without outlining her genitals.
"Huh, that's neat." Pup said as she raised her foot underneath Umi's leg. She pressed her foot up into the skirt where it met with Umi's right testicle. "You really can't tell it's there."
"Yeah." Umi looked to Pup, who playfully tapped her testicles with her foot, then back to Rena, who met her gaze with her piercing blue eyes. She suddenly remembered what she had done right before she passed out, and her heart began to pound. She quickly turned back around, too nervous to face Rena.
