What has gone before: 
Ranma Saotome, a 16 year old martial artist, goes to visit his fiancee 
Akane Tendo accompanied by his mother Nodoka and twin sister 
Ranko.  While there, they learn that not only are they the heirs of 
the Anything-Goes School of Martial Arts, but the heirs of the 
Almost Anything-Goes Marital Arts Lovemaking School.  Ranma 
and Akane are given the option to break the engagement after a 
week, but choose to let it remain after a few days.  To seal the pact, 
the two spend the night together, and are joined the next day by 
their sisters when Akane refuses to make a vow of exclusivity.  
Nodoka decides to take them on a month-long training trip to keep 
their school a secret, even from Soun and Genma.  Shampoo and 
Ryoga arrive from China chasing the Ranma, but reach Nerima too 
late.  Ryoga promptly gets lost and Shampoo finds a job at Dr. 
Tofu�s clinic, determined to wait them out.
***************

Episode 2:  Reunions

Ryoga cursed Ranma for the millionth time somewhere in the 
vicinity of Osaka.  Not only did he run out on their fight, but he was 
cursed while following them so that he turned into a baby black pig 
whenever he got drenched by cold water.  He had one week left to 
reach Nerima if he wanted to be there when Ranma returned.

He wasn�t sure if he�d kill Ranma, but he�d definitely beat him up.  
No, he�d kill him.

***************

Shampoo was bored, and as the proverb went, there could be 
nothing worse.  She had waited three weeks for the return of her 
prey, Ranko Saotome, the girl who defeated her in Jokusetzuku the 
day of the tournament.  She had spent those weeks employed at Dr. 
Tofu�s clinic as an apprentice nurse, most of which were spent 
helping treat injuries that would have been borne proudly (as a sign 
of age, and therefore respect) in the village.  Still, his kind and 
gentle manner gradually wore down her disdain for such an attitude.

She had figured out why everyone was convinced that Ranma was a 
boy and not a girl (and vice versa for Ranko).  She had looked at Dr. 
Tofu�s medical records and Ranma was clearly a boy.  They must 
have switched names when they went to China to confuse any 
pursuers.

Part of the problem was that there was no challenges in Japan.  
There was that boy who tried to attack her with a wooden sword, but 
he was too easily beaten and she didn�t care for his proprietary 
attitude even though he lost.  Shampoo hated to admit it, but she 
wanted to meet Ranko again, and not just to kill her.  She was the 
only one she could look upon as an equal.  Maybe she could 
convince her to become a blood sister and therefore a member of the 
village.

Then she could seduce Dr. Tofu and they could all go back to the 
village and be happy.  Her Great-grandmother would surely be 
happy at the thought of a doctor as a great-grandson and at a new 
student.  Ranko could even bring along her brother and his fiancee.  
But that was just a fantasy that she fell asleep to.  Inside she knew 
she had to kill her.  And Dr. Tofu was already involved with 
someone.

***************

Soun and a panda danced for in the streets at the news of Ranma 
and Akane�s marriage, then continued to dance at the thought of 
returning to Kasumi�s and Nodoka�s cooking, then at the...

Nodoka shepherded the others into the house, and was partially 
shocked at the mess that cluttered the kitchen, the living room, the 
bathroom...

Nodoka quickly called Soun and Genma and started them on 
cleaning up the dojo.  Everyone else went upstairs to reclaim their 
rooms.  Everyone smiled at each other as they enter their separate 
rooms; they had spent the last month sleeping in the same room and 
it would be strange going back to the way things were before they 
left.  They had all found out one important thing about themselves:  
that like Nodoka, they found that the lovemaking techniques were 
fine every once in a while, but they preferred not to use them unless 
they had to.

Ranma and Akane entered what had previously been only her room.  
Truthfully speaking, they weren�t married, but Nodoka had said that 
the lie was the only way they could be together without sneaking 
around.  They didn�t mind.

They had reached a sort of compromise on their relationship.  They 
would be married for real after they graduated from high school, and 
at that point they would vow to remain exclusive to each other.  
Until that point they would welcome any of the others if they wanted 
to join them, but their sisters knew that they preferred to be alone.

Akane made room for Ranma�s things (there wasn�t that much, 
mostly clothes), then sat on the bed.  She felt a little tired from the 
journey, so she lay down on her side and watched him unpack.  
After finishing, Ranma looked at Akane on the bed and stripped 
down to his underwear, slipping under the covers.  Akane got up 
and removed her clothes, leaving only her panties.  From outside, 
she could hear Kasumi telling Nodoka that she was feeling a little 
unwell and would be visiting Dr. Tofu.  Akane smiled to herself and 
joined Ranma under the covers that he held open for her.  The two 
soon fell asleep, Ranma�s arms around Akane�s waist as she closed 
her eyes and held his hand.

***************

Kasumi picked her dress carefully, a low-cut affair that would slip 
easily off her body, with a long skirt that almost touched the floor.  
The material was thin enough to be light and airy, but thick enough 
to hide the fact that she wasn�t wearing any underwear.  The 
upcoming event excited her, causing her to caress her mound.  She 
immediately stopped herself.  It wouldn�t do to walk around with a 
wet spot on her skirt.  She pulled on a light sweater so that she could 
slip unnoticed past her father.

Kasumi walked slowly to the clinic, centering herself.  Today was 
the day that she would make love to Dr. Tofu and cure him of his 
�love hysteria� for her.  She hoped that he felt the same way for her 
as he did a month ago; she was not the same person that she was 
when she left.  His patients made way for her once they saw  her 
coming, just like they always had, but now she noticed them and 
knew why they ran away.  Kasumi smiled to herself; she and Dr. 
Tofu would have complete privacy.

Kasumi frowns as she enters the clinic.  Inside is a girl dressed (if 
that was the term) in an incredibly tight and revealing combination 
of a chinese dress and a nurse�s uniform.  With her new 
appreciation of such things, she immediately noticed that the purple-
haired girl was quite cute, and for a moment wondered what it 
would be like to make love to her.  But then she wondered if this girl 
had made any moves on Dr. Tofu.

Dr. Tofu walked into the room then, surprised to see her.  Kasumi 
could definitely the change in Dr. Tofu�s behavior.  She licked her 
lips as she thought of what lay ahead.  Dr. Tofu introduced the other 
girl as his new apprentice nurse, Shampoo, and then introduced his 
skeleton as her.  Kasumi blinked as Shampoo ran to the back to get 
some sort of balloon on a stick and then leave the clinic.  What a 
strange girl.

***************

Ranko kicked open the door to Akane�s room.  Ranma and Akane�s 
eyes flew open as they watched her push through the door, her arms 
full with Ranma�s futon.  She dropped it onto the floor and smiled at 
them.

Ranko:  �Just cleaning my room.�  [sighing]  �I envy you, Akane.  
	You�re the only one of us that�s going to be getting it 
	regular for awhile.�

Ranko sat on the side of the bed, then french-kissed both Ranma and 
Akane.  She was taking a chance that Genma wouldn�t burst into the 
room to take them for some martial arts training.  She quickly 
jumped to the other side of the room, winked at them, and quickly 
lifted the front of her shirt to flash them her bra-clad chest.

Ranko:  �Got to go back to cleaning my room.  See you two later.�

Ranma hugged Akane a little tighter as Ranko closed the door 
behind her.  They had both explored (and been explored by) every 
inch of Ranko, Nabiki, and Kasumi during their training.  They had 
slept in the same room and became the best of friends again.  They 
fought, of course, but they found that the best way to deal with it was 
to just hold each other when they went to bed until it didn�t seem so 
important.

Ranma:  �Do you miss having the others around?�
Akane:  �A little.  I�m glad you�re here, though.�  [laughs lightly]  
	�In the same bed that I lost it to you about a month ago.�
Ranma:  �I lost it to you, too.�
Akane:  �I know.�

****************

Shampoo ran through the streets of Nerima.  Her day had come at 
last; she would be able to fulfill the �Kiss of Death� and finally go 
home.  She refused to allow the thought of losing to enter her head.  
It was true that Ranko had defeated her that day, but she wouldn�t be 
trying to kill Shampoo, which would be her mistake.

Shampoo burst into the Tendo Dojo and headed for Ranma and 
Ranko�s room.  During the three weeks she lived in Nerima she had 
prepared for this day; sneaking into the Tendo Dojo and learning its 
layout, talking to people about her prey.  She ran through the house, 
trampling over the pet panda and the Tendo patriarch who were 
scrubbing the floor and knocked the room door down with her 
bonbori.

Ranko turned from arranging her clothes in the closet, surprise on 
her face at Shampoo�s entrance.

Shampoo:  �Ranko no fool Shampoo with name again!  Die!�
Ranko:  �Shampoo!  What are you doing in Japan?�

Ranko quickly threw one of her dresses into Shampoo�s face, and in 
the split second gained, ran down the stairs into the bathroom.  
Shampoo quickly followed to find a wet boy whom she now knew to 
be Ranma.

Shampoo:  �Ranko?�
Ranko:  �Heh, heh.  Not here.�

Shampoo looked into the bath.  There was no one there.  She saw 
Ranko turn into the room, and now she somehow lost her.  Shampoo 
patted Ranko�s chest to make sure that she was a man.  There was 
no sense in threatening the brother; if she was going to check him 
out as a possible husband (even if the rumors were that he was 
already engaged) it would be best to stay on his good side until he 
proved unworthy.  Shampoo quickly left to hunt for Ranko in the 
neighborhood.

Ranko went to warn Ranma.

****************

Nodoka:  �Genma!  What was that all about?�
Genma:  �Growf.�
Nodoka:  �Don�t �growf� me!  I want an explanation and it better be 
	good.�
Genma:  �Growf... yow!  Hot!�

****************

Kasumi closed and locked the door behind her to ensure that no one 
would bother them.  Nodoka had said that she would have to lead 
Dr. Tofu, at least in the beginning, and that she would know when 
the �Love Hysteria� had passed because Dr. Tofu would act startled 
and disoriented.  Kasumi removed her sweater.

Dr. Tofu:  �Kasumi!  So nice to see you again!�
Kasumi:  �Did you miss me, Dr. Tofu?�
Dr. Tofu:  �Of course, of course, would you like to go for a walk?  Its 
	not much for a first date, but its such a nice day out...�

Dr. Tofu enters the kitchen.

Dr. Tofu:  �Oh look, a flower, I�ll pick it for you.�

Dr. Tofu picks up a plate and hands it to Kasumi.  Kasumi takes the 
plate and puts it on the counter.  She takes Dr. Tofu�s hand (causing 
a slight burst of giggling) and leads him to the examination room.

Kasumi:  �I thought of you while I was gone.�
Dr. Tofu:  �Well, isn�t that nice?  I thought of you, too...�

Kasumi sits Dr. Tofu onto one of the chairs, then sits on his lap, her 
arms around his neck.  She removed his glasses and put them on the 
side.

Kasumi:  �Dr. Tofu, I�ve waited so long for this day.�
Dr. Tofu:  �You have?  What�s so special about this day?�

Kasumi answered by kissing Dr. Tofu.  From below, she could feel 
his member stiffen and tease her basal lips; even if his mind didn�t 
entirely realize what was happening, his body did.

Dr. Tofu:  �I seem to have an erection.  I hope you�re not shocked.�
Kasumi:  �Not at all.  I think its nice.�

Kasumi ground her hips into his lap as she kissed his neck.  She 
then stood up, placing one hand on the drawstring of his pants and 
loosening it, the other hand caressing his manhood through the 
pants.

Kasumi:  �Oh, Dr. Tofu, I hope you won�t think I�m a slut after all 
	this.�
Dr. Tofu:  �Why, Kasumi, I could never think of you...�

Kasumi slipped Dr. Tofu�s pants and underwear down to his ankles 
and kneeled between his legs.  She looked at the erect cock (she had 
learned the �correct� term in the course of her training) for a 
moment and kissed the tip.  Dr. Tofu stopped talking as she grasped 
the shaft and pumped her hand along its length.  He shuddered 
when she stopped kissing it and started to lick, drawing her tongue 
slowly along the vein, circling the tip while it was engulfed in her 
mouth.

Kasumi started to bob her head up and down his shaft; he was 
rapidly approaching his release.  With only a second�s warning, his 
seed burst into her mouth.  She swallowed quickly like she had been 
thought, her lips locked into their position as he started to soften, a 
last intimate kiss in case he couldn�t stand to be around her 
anymore.

Dr. Tofu looked down at the woman who had stopped her 
ministrations and now looked up at him with fearful eyes that were 
starting to tear.  It seemed to him that he was of two minds; one 
which knew that he had just come out of the Love Hysteria (a 
condition which he had read about but never thought to encounter, 
much less suffer from) and one that knew he had been in love with 
the growing girl but couldn�t express itself until she did.

Kasumi:  �I knew you were going to think I was a slut.�
Dr. Tofu:  �No!  I could never think that... I love you.�
Kasumi:  �Oh, Dr. Tofu!  I love you, too.�

Kasumi hugged Dr. Tofu�s waist.  He placed his hands on her arms.

Dr. Tofu:  �I just thought... we�d be married before we did this.�
Kasumi:  �Oh, Dr. Tofu... is that a proposal?�
Dr. Tofu:  �I... I... Yes.  Do you want to get married?�
Kasumi:  �I hardly know you, Dr. Tofu.�

Kasumi pulled back to give him a good view of her cleavage.

Kasumi:  �I think we should get to know each other first.�

Kasumi took his hands and slipped them into the front of her dress, 
then pulled the straps from her shoulders to give him better access.  
She moaned as he started to caress her breasts in his grasp.

****************

Nodoka:  �Well, now that my husband and children have explained 
	what happened in China, we have to decide how to deal 
	with the problem.�
Nabiki:  �Maybe Ranma can convince her to leave us alone.�
Akane:  �Nabiki!�
Soun:  �Nabiki, how can you suggest such a betrayal of your sister?�  
	[starts to cry]
Nabiki:  �I didn�t mean it that way.  Sheesh.�
Ranko:  �I can talk to her.  She doesn�t know about the curse.  As 
	long as I�m a guy I should be safe.�
Nodoka:  �Very well, Ranko.  If that doesn�t work we�ll see what 
	else we can try.�  [looks around her]  �Hmmn... now that 
	the house is clean again, it is time for Dearest and I to take 
	our week�s vacation.  Ranko, if you still have problems with 
	this girl you have my permission to see me during a quiet 
	time.�
Ranko:  �Yes, mom.�

Genma gulps.  Nodoka drags him to their room.

Ranma:  �You think we�ll see pops alive again?�
Ranko:  �Don�t know.  They�ve never taken a week off before.�
Akane:  �Ranma, what is this �week�s vacation�?�
Ranma:  �Oh, well... mom and pops are going to... you know.  And 
	that�s all they�re going to do for a whole week except for 
	sleeping and eating.�
Akane:  �Well, Kasumi might not be back for some time, so I�ll 
	prepare lunch.�

Everyone else gulps.

****************

Shampoo grew tired with her futile search for Ranko.  She decided 
to go back to the clinic, perhaps she could talk to the Tendo sister 
that came in and glean some small bit of information from her.  She 
reached the clinic but found the front door locked.

She went around the side of the building and peeked into a window 
that looked into the examination room.  Her hand lifted the front of 
her short dress and found its way into her panties at the sight she 
saw; she quickly looked around and jumped into one of the nearby 
trees to make sure that no one saw her.  From her vantage point she 
had a perfect view of the couple inside.  Her hand returned to 
rubbing her sex.

****************

Dr. Tofu slipped his hands under Kasumi�s arms and brought her to 
sit on his lap again.  Somewhere deep inside he knew he shouldn�t 
be doing what he was, but he found that he couldn�t stop himself.  
After all, he was only a man like anyone else, and she was a woman 
that he had loved for years.

Kasumi was so wet that she just wanted him inside her.  His cock 
had regained its vitality and was once again poised at her entrance; 
she wiggled her hips, parting her lips with his manhood and then 
sliding down with delight.  Dr. Tofu gasped... he hadn�t expected 
things to go this fast.

Kasumi:  �Oh, Dr. Tofu... you feel so good inside me.  Ohh... yes... 
	kiss my tits!�

Kasumi leaned backwards as Dr. Tofu trailed kisses down to her 
breasts.  She put a hand on the back of his head and smothered his 
face with her chest.  Feeling him start to stand up, Kasumi hung on 
to his neck with her hands and his waist with her legs.  Every step 
was sweet torture as she exploited her connection to him.

Dr. Tofu placed Kasumi�s ass onto one of the examination tables, 
then climbed onto it after her.  Kasumi used the time they were 
separated to turn her body toward him and to raise her legs onto the 
table.  She saw his spear glistening with her juices, wanting to lick 
it, to clean it again, but wanting it inside her even more.  Dr. Tofu 
looked down, looking at the woman who was ready to accept him 
into her again, her dress top pulled down to her waist, her skirt 
hiked up to allow him a perfect view of the lower half of her body.  
She moaned as Dr. Tofu leaned his hips closer and ran the tip of his 
manhood down her outer lips.  Dr. Tofu took her legs and placed 
them on his shoulders as he slowly entered her.  Kasumi�s hips lifted 
off the table to meet his.

Shampoo watched the encounter through the window, noticing 
everything.  From the length and thickness of Dr. Tofu�s manhood 
to Kasumi�s body writhing underneath his.  She could see her 
yelling out �Fuck me, Dr. Tofu, Fuck my cunt good!� through the 
window, even though she couldn�t hear her; every thrust lifting her 
hips to get him to penetrate deeper, every meeting causing the table 
they were on to shake dangerously on its supports.  Rubbing the 
outside of her mound had no longer been enough for Shampoo.  She 
started to penetrate herself with her fingers, first one, then adding 
another and another when she needed it.  Her panties were already 
soaked and she desperately would have wanted to touch her breasts, 
except that she needed her other hand to steady herself.
