A/N: This is an optional chapter. What I mean is if you're contented with the verbal affirmation of love between the main characters, skip this chapter. But, if you believe that there has to be a physical affirmation (If you know what I mean), then read. Be warned though because it's not a work-safe chapter (i.e. don't read during office hours). For those who do not want everything portrayed in detail, you can proceed to Chapter 21(op2).

Chapter 21(op1): Light

"I guess it's due to too much muscle tension when we demonstrated the strikes and blocks." Natsuki said while relaxing on Shizuru's bed. "You mean your joints don't react when you cut with a sharp blow using a shinai?"

"I'm flexible," Shizuru said as she threw herself over Natsuki on her bed. She reached up the nightstand to switch on the lamplight and then she used the remote to turn off the main light in the room. "You're probably ageing."

"You're older than me," Natsuki smirked. Shizuru crawled over Natsuki and she bent her leg for her knee to press Natsuki's crotch. Shizuru waited for a reply but Natsuki just reach up her hands to hold the small of Shizuru's waist and the pattern of her breathing began to change. "Did you lock the door?"

Shizuru smiled at Natsuki's question. She was nervous at what she was about to do but she couldn't resist anymore. Besides, she did her research and Natsuki has given her permission. But still she was afraid. There were no more words coming from Natsuki, just a dazed look as Shizuru continuously applies pressure on her apex. Natsuki then bent her own leg to touch Shizuru's crotch. Natsuki felt that it was wet. She moved her thigh up and down to rub Shizuru's center and she received moans, moans that made her feel wet too. That was the go signal for Shizuru. She couldn't hold back anymore and she felt so hot at what Natsuki did. She lowered her lips to meet Natsuki and for the first time she darted her tongue. Natsuki instinctively opened her mouth allowing Shizuru to explore her. She made her own tongue dance with Shizuru's invading tongue. Everything felt right. It was too pleasurable and they were moaning at each other's mouths while they kept rubbing and pressing each others slit with their legs. Shizuru forgot everything she read. What she knew at the moment was to do what is pleasurable.

"Shi-Shi-Shizuru…m-more…Ah…Ah.."

"Ah…Yes Natsuki…mmm..Ahh.."

Natsuki's mind went blank. Shizuru felt that Natsuki has stopped moving her thigh up and down so she lowered her own crotch and began grinding it against Natsuki's thigh. Natsuki saw what Shizuru did and she was so aroused that she panted and threw her head back lifting her upper torso to touch Shizuru's full breast. They haven't undressed each other yet but jolts of electricity seem to spark everytime they touch each other.

Shizuru realized that if she keeps on grinding she might lose her energy to lead as she had promised, so she distracted herself with Natsuki's creamy neck and throat exposed in front of her. She began kissing and nibbling the soft skin while Natsuki kept on moaning and humming and occasionally expressing pain when Shizuru bites.

"Mmm…Shi-Shizu-ru…You'rrre…doing…great..Ah…Ah…mmm" Natsuki mumbled through her labored breathing. Natsuki's buds were pert and erect due to her overwhelming arousal and she felt that Shizuru was taking too long on her neck. Natsuki reach out her hands to pull up Shizuru's tank top exposing Shizuru's black lacy bra. Natsuki could see right through Shizuru's bra and her instinct tells her that she needs to remove the offending fabric. She caught Shizuru's attention and Shizuru also quickly pulled out Natsuki t-shirt. Natsuki lifted her torso to help Shizuru and the t-shirt was thrown away by Shizuru. Shizuru brought down her lower body to clip Natsuki's waist then she began kissing the soft skin above Natsuki's pert breasts. Shizuru unclasped Natsuki's bra and then she ran her hands up and down Natsuki's sides.

"Mmm…Ah Shizuru…Shizuru…" Natsuki couldn't think of anything but Shizuru's name.

"Nat-su-ki, do you like it?" Shizuru teased when she felt that she's finally getting the hang of it. Natsuki's flushed skin aroused her all the more. She realized that there are soo many things that she could do to Natsuki now. She could even experiment.

"…Shi..Shizuru..just…go…on…please…mmmm….ah..ah..ah..mmm"

Shizuru didn't waste time. She lifted her lower body and slowly she slid her throbbing center from Natsuki's knee to her thigh. She did this for her own pleasure and then she began pleasuring Natsuki again. She hastily pulled off Natsuki's denim bra and she grinned at the sight - two erect buds just right to match Natsuki's taut frame. They seemed soft and mouthwatering. Shizuru felt something was traveling inside her body. She wanted to rub her sex again, against Natsuki's thigh. She decided to pleasure Natsuki while pleasuring herself. Shizuru kneaded Natsuki's breasts at the same time while grinding her pulsating, hot, womanhood against Natsuki's thigh. When she felt that she was getting closer to the edge, she stopped grinding and she lowered her mouth to capture one of Natsuki's nipples.

"Ah! Shizuru! MMMMMMMM" Natsuki's moans were louder and labored. Natsuki doesn't know the meaning of her own word but she muttered, "Harder…please."

Shizuru sucked and flicked Natsuki's nipple with her tongue while squeezing the other one with her right hand. She also pinched the nipple with her thumb and index finger eliciting loud squeaks from Natsuki.

"Ah! Shi-Shi-zu—ru…Ah!..Uhnn..Uhnnn....Ah!" Natsuki's head was thrown to the side. Her hair was wildly splayed on Shizuru's pillow.

"I want all of you Natsuki. You're so beautiful," Shizuru spoke huskily while tracing a wet path with her tongue between the valley of Natsuki's breasts. She then began sucking Natsuki's other breast while squeezing the other one. Natsuki panted hard and she lifted her hands to Shizuru's mane. Shizuru then felt that Natsuki was pushing her head down and she knew what Natsuki wanted.

"Shi-shi-zuru…please…I…I…want you…inside…." Natsuki pleaded not knowing what exactly she is asking for. She just knew that only Shizuru could release her from the overwhelming need of her womanhood. Her mound of Venus was wet and throbbing and Shizuru was driving her crazy with her touch and kisses. In her mind, she was grinding her center against Shizuru's tongue.

Shizuru, traveled downward by leaving a trail of wet kisses on Natsuki's tummy and then Natsuki lifted her waist to show which part of her body needs Shizuru the most. Shizuru smelled an intoxicating smell coming from Natsuki's womanhood. Shizuru slowly pulled Natsuki's boxers leaving her wet navy blue lacy panties. Shizuru spread Natsuki's legs apart and she place her body in between. She looked up at Natsuki and she saw her chest heaving.

"Nat-su-ki" Shizuru called. Natsuki opened her watery eyes and looked down.

"It's…it's embarrassing…but—Ah!"

Shizuru was still looking at her but she used her middle finger to rub Natsuki's hot, and wet center. She loved Natsuki's reaction. She pressed harder and began a slow pattern of strokes.

"Uhnnnnnn….Ahhh…Shi-zu-ru…Uhhnnnnnn..Ah…more…please." Shizuru then sat on bent legs and lifted Natsuki's legs quickly and she hung them on her shoulders. She continued her assault of Natsuki's womanhood by munching through her panties.

"Mmmm, I like Natsuuuki here." Shizuru mumbled.

"Ah!..Ah!..Ah!" It was too much and yet Natsuki wanted more. She even pushed her own crotch against Shizuru's mouth gnawing her wet slit through the thin fabric of her panties. "Re-re-move…Shi.."

Shizuru obliged by pushing aside Natsuki's panties and then she licked her slit.

"UHHHNN…SHI…UHNNNNN"

Shizuru then slid down the offending garment so she could get directly to her prize. Her own center was drenched but her urge to go deeper into Natsuki was so great. Again, she hung Natsuki's legs on her shoulders and held them tightly because Natsuki began to wildly shake them.

"Natsuki, you're beautiful," Shizuru madly said and she lost all self-control. She started with a slow, long lick on the entirety of Natsuki's slit as if she found the sweetest honey on earth. Natsuki's mound of Venus was dripping with white juices.

"AHH…UHNNNN…PLEASE...."

Shizuru saw Natsuki's clit and she pressed her lips against it. The pressure traveled down the whole of Natsuki's body and she shook her legs violently but Shizuru held her firmly. Shizuru hardened her tongue to find Natsuki's center and then she found the entrance to her womanhood.

"HAH…HAH…AHH" Natsuki panted in anticipation.

Shizuru tried to push her tongue and then she realized that she had to use something harder. She gave Natsuki's center a long wild lick once more before she changed her position. She laid down Natsuki again and spread her legs apart. She then held Natsuki's body with her left arm while her finger began its work on Natsuki's tight center. Natsuki was happy that she could finally hold on to Shizuru's body. Shizuru slowly pushed her middle finger inside.

"UHHHNNN…" Shizuru dipped her mouth on Natsuki's nipple to distract her from the pain of her assaulting appendage. "Ha..Hard…Harder…" Shizuru then broke the thin membrane and completely deflowered Natsuki.

"AHHH!"

"Shhhh, it's fine Natsuki. I love you." Shizuru said. She was on her senses now, now that she's aware that this process is going to be a bit painful.

"HAH, HAH, HAH," Natsuki panted heavily. She felt Shizuru's finger filling the unknown void inside her, waves of pleasure hitting her insides from all directions. Shizuru then began to wiggle her finger inside and search for Natsuki's sensitive bundle.

"AH! AH!" Shizuru then felt Natsuki's muscles pulsating, clamping and relaxing. She pulled out her finger and quickly plunged it again, her palm beating Natsuki's slick and rosy clit in the process. She continued this steady rhythm while Natsuki lifted her lower body to meet Shizuru's painful yet pleasurable thrust.

"AH!AH!AH!AH!AH!AH!AH!AH!SHI-SHI-SHIZU-SHIZURUUUUUUUUUUUUUUU!"

All Natsuki knew was that it was Shizuru entering her. It was Shizuru who was driving her to the edge and when she couldn't take it anymore, the finger and the palm beating her slick nether lips, she felt her juices gushing out and she was blinded by the light suddenly surrounding her. Shizuru stopped pumping her when she felt that Natsuki finally came. She couldn't comprehend what they did. All she knew was that Natsuki was in her arms naked and exposed. It was never like what she read. There was no method. It was all about instinct. Her finger was still inside Natsuki's hole and she slowly pulled it out. Natsuki felt that it was removed and she gave one final moan. Shizuru laid her on the bed and she cuddled her as she pulled the blanket. She saw blood spots on the bedsheet and somehow she felt guilty but seeing Natsuki clinging on her took away her worries.

The sound of their breathing was the only sound in the room. Shizuru kissed Natsuki's forehead. Natsuki's breathing was slowly returning to normal. Shizuru was nervous of Natsuki's assessment and she couldn't sleep. She just kept on kissing Natsuki's forehead and cuddling her body close to her.

"Natsuki, are you sleepy now?" Shizuru nervously asked with watery eyes.

"Yes," Natsuki contentedly said almost inaudibly. Shizuru couldn't see Natsuki's face so she wasn't aware that she actually sent Natsuki to seventh heaven during their love-making.

"I'm sorry Natsuki. I hurt you," Shizuru muttered with tears in her eyes. Natsuki used her left energy to pull out herself from Shizuru's embrace and look straight in Shizuru's eyes.

"Silly, it did hurt but it was delightful," Natsuki softly said.

"I went out of control several times," Shizuru confessed while sobbing. The idea of hurting Natsuki because she couldn't hold back her desire was punishing her.

"I know but I…I"

"I'm…I'm sorry"

"Shhhhhh...Listen…I love everything you did Shizuru. Everything." Natsuki blushed at this confession as she remembered everything that Shizuru did to her. She had nothing to hide anymore. Shizuru wiped her own tears with the back of her hand and she looked at Natsuki with softened features. "You just tired me out. Now that I know how it feels like I wouldn't hesitate when I do it to you."

"Ara," Shizuru beamed. "I love my Natsuki."

Natsuki placed her hand on Shizuru's tummy and spoke huskily. "I'll make sure to bring you to heaven as well." Natsuki grinned and Shizuru shivered at the feel of Natsuki's hand on her tummy. "I'm tired so help me remove this." Natsuki pointed her finger at Shizuru's bra. Shizuru unclasped her own bra and threw it to the side. "And this too." Natsuki reached down her hand and palmed Shizuru's slit. Shizuru gasped and then she grinned.

"What if I don't want to?"

"Come on Shizuru. I'm weak. I can't move my lower body so please remove it and cling to me. I want to feel you so I can sleep peacefully so remove this" Natsuki rubbed Shizuru's wet panties and Shizuru knew she just had to comply.

"Alright, stop teasing me then. Natsuki pulled her hand up and brought it out of the blanket. She then seductively bit the tip of her own index finger. Shizuru slid off her underwear and move her entire body in contact with Natsuki's delicate parts. It felt so nice. Natsuki lowered her body and she buried her face in the valley between Shizuru's soft and generously proportioned breast.

"Good night Shizuru, I love you."
