In a secret series of spacious, dimly lighted gray chambers, located under one of the hospital complexes, a series of strong clashes reverberate throughout the area, one after another. Our heroes were granted the entry by Ryuuken, Uryuu Ishida's father. Due to the courtesy of Hachigen, who offered to stay outside and secure them for the time of their training our two heroes, Ichigo Kurosaki and Nelliel to Odelschwanck, were training fiercely to keep themselves in shape, just in case they need to fight with evil again.

*BOOM!*

*BANNG~*

*CRASH!*

The loud sounds accompanied almost all of the time when Ichigo's zanpakuto Zangetsu, clashed with Nel's lance Gamiusa. In a series of immediate but strong poses the heroes kept changing their poses, with an average onlooker only seeing the split seconds of their movements. However, if we looked closely enough, we would see that trickles of sweat were appearing more on Ichigo's skin rather than on Nel's.

Damnit! She uses piercing attacks, which are very hard to block with just a sword. I don't have a shield to block them, and in order to stop them from connecting I have to be precise in countering them...But she keeps thrusting me with hundreds of them! Agh!

On top of Nel's natural strength as the retired 3rd Espada, transforming into her centaur forme allows her to stabilize herself on the ground with the 2 sets of feet and a much, heavier body than Ichigo's, resulting in even more power allowed to be put into those thrusts. From a stricte human combat standpoint Ichigo would have a huge disadvantage, and the only thing allowing him to overcome that disadvantage, was his own vast amount of Reishi, the energy propelling all powers and feats of a Shinigami.
*FATHOOM!*

*Tfshhhhhh*

Ichigo was pushed back a few dozens of meters away by Nel's last attack.

"Getsuga! TENSHOU!"

Ichigo sent a blue wave of pure, trampling energy towards Nel.

"Cero!"

Nel easily created a beam of energy out of one of her fingers, which in quick succession started tearing through Ichigo's energy attack, until the both attack's resulted in a explosion, causing a shockwave and leaving white smoke everywhere to fill the room.

"Uaaaaaaaaa!"

Nel has got caught a little off guard, by Ichigo who leapt at her out from the smoke.

"Ah!"

She yelped as she couldn't quite block Ichigo's horizontal cut, which he aimed at the little fabric that kept her breasts together.
Now since the fabric was cut, her large breasts plooped out in the open.

"Kehe!"

"Ayyee! Sto! Stop! Ichi! Ichigoooo~"

Nel pleaded for mercy as Ichigo quickly snatched his chance to lock his lips on Nel's voluptuous boobs, and start sucking on them.

Nel yelped with her heartbeat represented in her panting voice:

"Ay! Pleease! Stop for a second! I can't have sex with you when I'm in this forme! Please allow me to transform back! Ayieee!"

On another time, Ichigo was coming back home from a quick scavenge to get rid of a few hollows pestering in the neighbourhood. As he came back into the residence where he and the four girls lived, he found it quite empty when he asked if anybody is in there, until.

"Hereee~ Ichigo!"

Nel's voice. Ichigo felt alerted that something is off, since Nel usually jumps on him always as he enters the house. Although she also ceased doing it recently. Which he preferred, because having her jump on him each time was bothersome to him. [readers, don't get mad, this will be addressed later ok? lol] But this time she was calling him to the living room.

As he entered the living room he saw Nel sporting a sweet smile, holding what seemed to be a huge sack of some things, secretly behind her legs.

"Whatsup? Where's everybody?"

"Orihime-san is at her new work. Rukia has went to Soul Society to attend some "ass-bothering family business"

"Aaand Riruka?"

"I sent her to the grocery, teehee"

"Now is a perfect time for the two of us to have some fun!"

"Wait..Nel...What are you...Wait! Waiit! Let's negotiate! I'm sorry for that thing earlier!whaa..Wait! What are you.."

Ichigo tried to defend himself from the imminent but it was futile. Nel was happily holding him up with two of her arms like he was a lifting weight.

"Hu..huhu..hhuuhu"

"What are you planning to do to me?!"

"Well..."

She lowered Ichigo to a "princess carry" kind of hold.

"You know, in your human television, I watched this program where they show those little humans."

"Little humans?"

"Yeah, like those little, bald, fragile things that seem to be always held closely by the women in those shows"

"You mean human babies?"

"Yes. Those. Be my human baby today Ichigo!"

"N-no way. NO WAY! I am not-! Agh! Nel! Nel! Don't!"

Nel's expression changed into a sinister grin.

Force me...

Now Ichigo was naked, wearing only a diaper, a coo, a baby veil and Nel was lulling him in her arms.

"Who's my cute little baby? Who?"

"Mmnghpsk!"

"You are! Little Ichi! Youuu. Does the baby want to go to sleep? Let mommy lull her baby to sleep."

"Mmmmmmnghpsk!"

"Oooouh. The baby is sad. Is the baby gonna cry? Let mama help youuu. Do you want to suck mama's breast? Here, little mama's boy!"

On the outside of the house, a few alleyways far from the residence, a pink haired grouch was walking fast in a steel, angry manner.

Buy the groceries! Buy the groceries! Do you send a handicapped person to buy the groceries?! ARRRRGH! I walked all the way to the shop just to get embarassed because I don't have my stupid glasses! Glasses suck! My vision sucks! How can they make me do those things!

She stormed quick onto the lawn of the house and into the house. She grabbed her glasses from the shelf in the antechamber, but then, as she were about to leave, she heard Nel's happy chatter with mumbling Ichigo.

Riruka crept as sliently as she could to see what's happening in the living room. She saw Nel's back, so she couldn't quite understand what's going on. Then, Nel started turning (while still lulling her baby) toward Riruka so the pink haired girl fretted and hid away.

Wha, what is going on? Not that I'm curious...

Riruka blushed.

Ah! I couldn't see very well. I didn't have enough time. Maybe if I go into the garden and peek from the window. Gotcha!

Riruka quickly and stealthily went into the garden, then ducked below the window, slowly trying to see what's going on equipped with her comical-looking huge glasses, eyes wide open and sporting a red blush on her face.

"MMMmmmmcp! Mmmnhha!"

"Ah, how is it now? Did you like having mother's milk?"

Ichigo's drool was all over Nel's breast and he was panting hard as she forced him to suck it for almost twenty minutes.

"Well, too bad it was only imaginary milk. Oh, but here I have a bottle of real warm milk for you!"

"GhuuPhhhhKkkkk!"

Ichigo was gargling on the milk that invaded the inside of his mouth, as Mother Nel's brute strength made her squeeze the plastic bottle so that the contents of it were gone in seconds.

"Okay! Now mommy will lay with you to sleep okay? We're gonna take a sweet nappy-nap together, alright, little baby?"

Ichigo seemed to have passed out with a lifeless face from the amount of physical stress already. He didn't respond much.

Still holding him in her arms, they went together into the bedroom.
Oh wait! I cannot see if you go there! The blinds are upon the windows of the bedroom! Ahhhh...Wait. Why do I want to see that? Anyway, this was so weird. Right? Poor Ichigo, always getting tortured by that cave troll. There's no way that being held that way and having such things done to you would be fun. Right?
Heck, I don't even wish to imagine myself doing those things to him.

Riruka visualised herself being held by Ichigo in the baby's outfit.

Right? So ridiculous. There is no way that sort of thing could arouse anyone now, c'mon. Wait, why did I imagine myself being the baby?!

Actually the results of it were quite the opposite of what Riruka thought. As Nel removed Ichigo's diaper, his huge hard dick was already pulsing and stayed hard for some reason. Probably because of the breast sucking and Nel staring right into Ichigo's eyes the whole time she was lulling him.

Laying the still unconscious man on the bed, she took his long shaft and started giving him a nice fellatio.

Ichigo couldn't not have woken up back to his senses from that.

"Ahhh. Couldn't you have done that from the start?"

Nel punched him hard in the face.

"Ouch! I'm sorry! Gosh! How many times are you going to beat me...Ouch, my nose..."

Nel resumed sucking Ichigo's cock.

After a while when it was glistening from her saliva, (which also miraculously revitalized him from the previous ordeal, thanks to special potential of Nel's drool) They were both ready to get it on.

They stood up, kissed, then Ichigo lightly turned her toward the bed and made Nel fall on it so that she was in the missionary position, naked, of course. He embraced her close and gently on the bed, and kissed once again, now with a serious expression on his face.

"I'm sorry for treating you badly back then. I promise that will never happen again."

"I'm sorry too. I probably went a little overboard with the babying. Thank you for being submissive though. I always really wanted to do it."

"I wouldn't mind even if you'd want to do it to me sometimes again, Nel. As long as I can see the happy expression on your face.
I love you, Nel."

"Ichigo!"

Nelliel teared up a little, hearing Ichigo's words and reconciling with him.

They started having heated sex, with Ichigo putting in all his might to make Nel feel good, and she did vice versa. They fell to sleep after together like that. The rest of the girls, which was Rukia, Orihime and Riruka assembled later that evening.
