Mani lifted up he pencil next to her side and placed it against the white paper in front of her. Halloween was only four days away, she had to finish her assignment. Glancing up she noticed Kazuki in the door way of the art room, "Hey Kazuki...Taro's gone home already." she said putting her pencil down and standing up. Her breasts bouncing as she fixed her shirt and crossed her arms. "So, I heard from Lana that you're going with Sarah to the halloween party this weekend." she said clearing her throat slighty. "It's about time you got a girlfriend.."

"Who told you that?" He said, shrugging his shoulders. "She's not really my girlfriend, just going to a party with me." He averted his eyes when she looked up at him so he wouldn't be caught staring at her bouncing chest. "So who are you going with? And more importantly... what are you going as?"

"I just said Lana told me." Mani said blinking slightly and laughed under her breath. "I'm just going by myself with Taro. It's not a big deal if I don't take a date." she looked down at her sketchbook then up at him, "That...is a surprise."

 "What's a surprise?" He asked, reaching for her book and pulling it from her hands to get a good look at it.

"Hey!" Mani reached out for the sketchbook as soon as he opened it a picture of a girl bound up was in it. "I-It's not in there!" she said snatching it back blushing blood red. "I'm going as a cowgirl!" she swallowed slightly blushing like mad. "Erase that picture from your mind.."

"Well, aren't you a kinky one Mani. I never would have thought. Guess it is always the quiet ones..." He said with a laugh. "Don't worry, your secret's safe with me. Anyway I gotta go, see ya around Mani." And with that, he tossed her book back to her and left her alone in the art room.

"Kinky one?" Mani sighed to herself and gathered her things together. She knew he would make fun of her outfit at halloween, but she brushed it off. "Kazuki!" she called out standing up and clearing her throat. "Would you walk me home?" she asked looking up at him. "I usually don't ask...but it's dark outside now and yeah.." she looked away clearing her throat. "Taro also asked me to help you with your math homework."

"What, you afraid someone'll come up and kidnap you...? Judging from that picture you'd probably enjoy it." He said, grabbing her teasingly from behind and holding her hands behind her. Laughing, he released her, secretly sneaking a glance as her breasts bounced, before coming up beside her. "Fine, I'll walk you home, just get your stuff."

Mani blushed slightly as soon as he touched her, and looked up at him. "Alright." she said turning away and going back to her section of the art room. Grabbing her things she looked up at Kazuki, before standing up. "Let's go." she said walking ahead of him slightly. It was quiet until she got home, "So, Come on in." she said opening the door up. Taro was out and about with his girlfriend, so they had the house to themselves. "I need to help you with your homework."

"I said i'd walk you home, I didn't say anything about homework. I'm fine, I don't need any tutoring, and I don't want any either." He replied. "Just go do your own homework, I'm going home."

"Not according to Taro.." Mani said timidly. "Come on, we can do that weird strip poker thing...the thing we used to do with my barbie dolls. It'll be interesting." she said shrugging slightly. "Come on." she grabbed his hand timidly and pulled him inside before closing the door. Pulling him along behind her, she glanced over her shoulder at him as she closed her door. "Work on the first problem, you know the rules."

"Fine..." He said as she pulled him inside, a grin forming on his face. "When you put it that way, how can I refuse?" The game went well for Kazuki; he got bad grades cause he was lazy, but he understood the material perfectly. 20 minutes later he sat across from Mani grinning at her as he got another question right. "Alright Mani, you lose again. Now... lose the shirt." She was almost out of clothing, already without her pants, and all that remained was her shirt, bra, and panties.

Mani swallowed slightly and took off her shirt. Placing it to her side, she reached out and grabbed her sheets. Pulling it around her, she stood up. "T-That's enough...I'm not taking off my under garments." she said standing up. "You under stand the work....you can go home now."

"Oh no you don't!" He said, pulling the sheets down from her, revealing her rather large breasts, which bounced from having the sheets yanked down. "You can't cover yourself up, that defeats the whole purpose... and besides, I've still got a couple more problems... don't worry though, you don't have to take off your underwear... I've got another idea."

Mani stared down at him. "What...other then this?" she asked reddening by the look in his eyes. "You're looking at me weird."

Kazuki gave her a smirk as he answered another question right and moved around behind her, staring down her bra from above. "Of course I'm looking at you... I've got you in your underwear, and well... those boobs of yours are huge." He said, reaching around to squeeze one of her breasts, lifting it slightly and allowing it to fall again, causing her chest to bounce. "Who'd have thought little Mani would grow into such a busty woman." Without giving her a chance to respond, he grabbed the tie from her school uniform, pulling her hands behind her and tying them in place behind her back. 

Mani looked over her shoulder at Kazuki, "I-I...didn't say you could touch my chest." she said wiggling up as soon as he bound her arms up. "Kazuki, untie me...!" she blushed like mad as soon as he spoke to her pervertedly.

"Well it's either that or you lose the bra. I wouldn't mind seeing more of your boobs but I don't think that's what you want... so now... I get to tie you up a little more for each one I get right. Now, hush, or my next question I'm gonna use to gag you." He said. "But feel free to keep struggling... I love watching those big boobs of your bounce around." He said with a laugh.

Mani curled up on her bed. "No, I told you the game was over with. Now stop it before I call for Taro.." she said covering herself as best as she could with her pillow.

 Kazuki finished his next problem, and true to his word, he moved behind Mani, sitting on her bed and pulling her into his lap, clamping a hand over her lips to quiet her down. "Hush you." He ordered, fondling her breasts as she struggled, growing hard and pressing into her butt slightly as she wiggled.

Mani moaned into his hand suprised and closed her eyes tightly unable to believe that he was touching her so freely. "K-Ka-Kazuki...this isn't." she wiggled in his lap slightly trying to calm down herself, but failed as she began to get turned on. 

 Kazuki laughed slightly as she wiggled about, and pulled a cloth over her mouth, tying it tightly over her lips. "There, that's my prize for the last question." He said, removing his hand now that she was gagged. "Unless you'd rather lose the bra and give me a better look at your boobs." He laughed as she wiggled, sitting her back on the bed. "Now... next question..." He answered the last of the questions and held it up for her to see. "So, did I get it right?" He asked with a smirk.

Mani looked at his answer and shook her head no. Before freezing up. Someone had come home earlier then usual. Wiggling around she began to muffle countless time at Kazuki.

Kazuki looked back at the problem and checked his math before turning and glaring at her. "You liar, it is right!" He said before a noise downstairs got his attention. Grabbing Mani, he lifted her over his shoulder and walked with her into the closet to hide. "Quiet!" He said as he held her close and she struggled. "I don't think you want to be found like this."

Mani froze up completely as soon as he covered up her mouth. "..." she turned around tiliting her head down into his chest trembling afriad as her brother opened up the door to her room, "Mani! What are you....doing home so early." he fell quiet seeing she wasn't there, before letting out a sigh. "That girl...where is she?"

Kazuki waited until Taro had left Mani's room before letting out his breath in relief, loosening his grip on Mani a bit, though he kept her gagged and tied while in her lap. "That was a close one... don't you ever lock your door, Mani? We could have gotten caught!"

Mani glared over her shoulder at him. Muffling something at him hatefully, and moving her shoulders up and down. She pulled out of his lap and began to move away from him.
