"Are you sure you want to do this?" Hajime asked her for the dozenth time.

"Yes. I…have been thinking about it a lot." Chiaki answered. The two were currently standing in the middle of an empty classroom, several hours after classes had ended. The two had met up after Chiaki had asked Hajime for help with something that she only trusted him with.

"W-well?" He asked. She nodded, and with a deep breath, she began undressing. She removed her vest and handed it to Hajime, who was already blushing just from seeing her take that off. After that she unbuttoned her shirt and took it off as well, revealing a lacy pink bra underneath. Hajime immediately couldn't help but look over, and the combined sight of her bra, her massive amount of cleavage, and the adorable little mole on her chest made him instantly horny as his face turned a bright red, and he looked away.

"It's okay…you can look." Chiaki said with a smile, her cheeks pink. "I trust you." She'd been wanting to try this kind of thing for a while, but had been scared to do it alone. She'd asked Hajime for help so that he could protect her, and help keep an eye out for others while she was going around. Plus…even though she didn't want to get caught, she did want to be seen by at least someone, just to see what it was like. Hajime gulped, and slowly looked back over at her, watching as she undid her skirt next, letting it drop to the floor, leaving her in just socks, shoes, and her underwear. Hajime could feel his dick straining in his pants as he looked at her, even more so as she reached behind her back and worked on unclasping her bra as well. Once it was done, and cups immediately loosened and she slipped it off, her face now matching Hajime's in color as he looked at it, his breath escaping him.

Somehow they looked even bigger than before. Adorable, hard pink nipples topped her busty mounds, and they jiggled as Chiaki shifted on her feet. Hajime had to resist putting a hand on his crotch as his dick throbbed in his pants. Chiaki giggled as she smiled to herself. "Do you…like them?" She emphasized the question by shaking them around a bit, making Hajime actually gulp.

"Y-y-yes…very much so." He said, and she giggled again. She slipped her fingers into the waistband of her panties, and paused. She took another deep breath, and finally pulled them down, stepping out of them before bending down to pick them up, leaving her chest jiggling more, especially when she stood back up. Hajime was surprised to see she was completely shaved, her pussy on display for him to see. Feeling his gaze on it, her blush deepened even further.

"A-are you ready?" He asked, and she made a sort of humming noise as she looked down at her feet. She shook her head and walked over to a desk, sitting down on it, lifting her leg up to take off her shoe. Hajime gasped as this left her in a position that left her pussy completely exposed to him, leaving very very little to the imagination. As she slipped off her sock, she seemed to realize this, and she whined a little, but the smile remained on her face, and she moved to do the other sock and shoe. Once she was done, she stood back up, now completely, bare ass naked from head to toe. She shuddered, and Hajime had to take a deep breath to calm his nerves as he clutched her clothes tightly to his chest.

"R-ready." She said, her voice shaky. She turned and started walking towards the door, now giving Hajime an excellent view of her smooth, slightly pudgy ass, which jiggled with every step. Hajime had to resist the urge to straight up grab one as Chiaki opened the door and peeked out.

"A-again…are you sure you want to do this?" He asked, and, still facing away from him, she responded by opening the door and stepping outside, so he quickly followed. The hallways were empty, but the two could hear very distant chatter of a couple students as Chiaki ducked to the other side of the hallway, into the women's bathroom, peeking out and around, while Hajime simply followed her out, holding the clothes.

"Be careful, okay?" He said, stating the obvious. Chiaki gulped, and took a step out into the hallway again, then another step, and then another, until she was back out of the bathroom, and completely out in the open. Her hands, like the rest of her body, were trembling, but she didn't cover herself. She couldn't help but laugh. She was naked, completely naked, out in the open. She spun around on her foot, her assets swinging around as well as she giggled, and then bounced on her feet, making her chest bound accordingly. That only worked to make Hajime even hornier as he kept frantically looking around.

Then, Chiaki started walking down the hall, and Hajime had to pause to get his bearings for a moment before following her. Her giggles echoed through the empty halls as she whipped around the corner, and saw the windows, looking out into the courtyard, where a few students stood talking and doing whatever else. Chiaki smiled and walked up to the window, pressing her body up against it, shuddering as her hard nipples touched the cold glass and her boobs squished against them. This left her slightly bent over, and Hajime, despite his nervousness, was enjoying the view. Before he could say anything though, he heard a noise, and turned around, freezing. Coming down the hall towards them…was Chisa!

"Uh, Chiaki! We…we need to go…" He said as he turned to her, watching as she rubbed her breasts against the class, daring anyone to look up and see her. "Chiaki!" With Chisa rapidly approaching, and no visible place to easily hide, Hajime was trying his best to urge her to keep going, but she was seemingly mesmerized by the glass. Groaning, he grabbed her hand and started pulling her away, making her nearly trip as it finally seemed to snap Chiaki out of it, and they started running, hearing the teacher's footsteps getting closer and closer.

"Come on, we need to find a place to-" Hajime said, but cut himself off as they rounded the corner, and found Ibuki. Hajime stopped, but Chiaki kept going, and plowed into the girl, knocking her to the floor, ibuki's face getting buried in the girl's bosom. Hajime felt himself turn pale as a thousand bad excuses flashed through his mind.

"S-sorry, Ibuki…" Chiaki said as she got up, and became concerned when she saw the musician's nose was bleeding, but she gave the gamer a smile.

"Wow, didn't take you for the type~" She said.

"I-Ibuki! W-we can explain, look, she…uh…sheeeee had a spill! On her clothes! All the way to her underwear! Aaaand she didn't want to wear them so she asked me to help her get new ones! But…she didn't want to…to…ummmm…" His terrible excuse was quickly falling apart, but Ibuki just laughed as she and Chiaki stood up.

"Hey, you're not the first person I've ever run into streaking. Just the first who had a helper, which is probably a smart idea, to be honest!" Ibuki said, and looked Chiaki up and down, making the gamer blush again. "But damn girl…you're definitely the hottest one I've seen! Can I touch em?!"

"S-sure…" Chiaki said. Hajime was still freaking out, sure that Chisa was still one her way, but before he could say anything, Ibuki had her hands on the girl's chest, squeezing them so tightly that Chiaki moaned as her legs shook. Hajime's erection throbbed painfully as he stared dumbfounded at the display, Ibuki's tiny hands barely able to wrap around the girl's massive chest as she groped her. Fortunately, or rather unfortunately, it only lasted a few seconds before Ibuki stopped, leaving Chiaki panting.

"You've got somebody following you don't you? That's why you're so worried." Ibuki inferred, and Hajime nodded. "Don't worry, I'll help you with that, and you can keep on going enjoying yourself! Have fun you two!" Ibuki walked past them, giving Chiaki a spank on her butt as she did, making her squeal. "Hey, Miss Yukizome! I have a question for you!"

"Um…okay then…Chiaki, let's go! While we have the chance!" Hajime said, and started moving. Chiaki gulped as she started taking wobbly steps as well, following him down the hallway. She felt hot, and dizzy. Her pussy almost felt like it was throbbing, and her hands twitched. She wanted to…

"Nnnnn!" Chiaki gasped as she felt her finger press against her clit. She'd moved it without even thinking. The two rounded the next corner, and Hajime smiled as he saw the stairs. The two had agreed Chiaki would streak as close to the school entrance as she could before getting dressed again, and there was their path. Hajime turned to Chiaki to give her the good news, but to his horror, he found a strange…and hot sight.

Chiaki was up against one of the doors, her finger deep inside her pussy. Her chest heaved, her breasts moving up and down with her rapid breathing as she moaned. Her body trembled against the door as she frantically fingered herself, horny just from what had already happened. "Ch-Chiaki!" Hajime said, also immensely turned on by what he was seeing.

"I-I can't…Ha-Hajime…" She groaned as she banged her head against the door as she let out a loud moan. Hajime was freaking out as he looked around, making sure nobody was around to see this. Thankfully they were still alone, for now.

What neither of them knew however, was that Kazuichi and Gundham were on the other side of the door, their ears against it, listening.

"Is that…?" Kazuichi asked.

"Chiaki? I believe so." Gundham finished.

"And is she…?"

"Giving herself pleasure? I…believe so…yes…" They both listened intently, succumbing to their horny curiosity.

Back on the other side, Hajime was pleading with Chiaki to leave with him, worried somebody could show up at any moment, but she wouldn't listen. She was too wrapped up in her own arousal, having inserted a second finger as her moans became louder and louder. She occasionally moaned his name as well, which made him only more aroused, leaving him struggling not to take his dick out and start masturbating right then and there. Finally, she came, and Hajime couldn't look away as her cum sprayed out of her pussy, spraying onto her hand, her thighs, and the floor. She panted as it all flowed out, and when it was done, she nearly collapsed, before Hajime rushed to catch her. As soon as he firm, his arm became squished against her breast, and he shuddered, but held on to her. It only became worse, or better, when she turned to face him, pressing her entire chest against his as she looked up at him, still panting slightly.

"Hajime…" she breathed, and he shuddered again. That face…

"W-we need to go…" he said, and using him as support until she got her bearings back, they moved to the stairs and started making their way down. As they were descending, he looked back, and was horrified to see Kazuichi and Gundham leaving the room she had been laying against the door to, but Hajime and Chiaki ducked out of sight before they could be seen.

As they quickly made their way down the stairs, with Chiaki finally on her own feet again, they nearly got spotted by several more students, but eventually made it, the entrance in sight. Hajime was about to say Chiaki should finally get dressed, but before he could, Hiyoko walked into view and as soon as she saw Chiaki, her face turned bright red. Even so, she still smirked and laughed, pointing.

"WHAT ARE YOU DOING?!" She asked. "Streaking around and having your boyfriend carry your clothes for you? What, are you an exhibitionist? Because if so, who would ever want to see those disgustingly massive tits of yours?" She laughed, and started looking for her phone. "I gotta take a picture! You may be ugly, but I'm sure everyone would still want to see your fat-" Suddenly, she was cut off when Hajime rushed up to her and smacked her directly across the face. He'd accidentally used enough power that she stumbled back, nearly falling over both from the force and surprise. When she stopped, she looked up at him, her lips trembling, her eyes wide, frozen in shock as she clutched her cheek with her hand. Hajime stared back at her for a moment, before he shook out of his own shock, and was about to apologize before she started bawling.

"H-HOW DARE YOU HIT A GIRL! I-I'M TELLING MAHIRU!! AHHHHHHH!" She screamed as she ran down the hall, clutching her face as she did. Hajime sighed.

"S-sorry, I really didn't mean to hit that hard…it just kind of happened, I-" Hajime started explaining himself to Chiaki, but she was already walking towards the doors. He rushed up to her and grabbed her arm. "What are you doing?!"

"I just want to take one step outside. Just one. Please?" She asked, her body shaking as she breathed heavily. Hajime looked out, seeing a couple students still outside, and then back at her, ready to say no. But…her face…those eyes…he just couldn't.

"F-fine. But make it quick, okay?" He said, and let go. She smiled at him as she walked out and felt the sun on her bare skin, the concrete under her bare feet. She shuddered, making her breasts jiggle, and she couldn't help but laugh. It felt so…nice. Hajime kept an eye on the other students, who hadn't noticed her yet. But as she started to walk out further and further, he rushed forward and grabbed her arm again, exclaiming "Chiaki!" But he'd said it a bit too loud, and the students looked over. All they saw however was the entrance, as Hajime had pulled her back inside and up against the wall, their bodies touching, their chests connected as he accidentally pressed against her.

"H-Hajime…" She groaned, and he pulled away.

"S-sorry." He said, but she shook her head, and held out her hand. With a nod, he handed her her clothes, and kept watch as she redressed. It didn't take her long to put everything back on, but it definitely looked like she was disappointed to be wearing everything. "How…was it?" He asked, and she smiled, before leaning forward and giving him a kiss on the cheek.

"I can't wait for next time." She said, before she walked out the doors, leaving Hajime stunned as he watched her walk away…watching her ass move, and still wildly horny.

"I need to masturbate." He said, and ran off as well, as fast as he possibly could.
