It had been some time since Rias had been freed of Riser's arranged marriage. She and Issei had been dating since then. And while he was still having a Harem, Rias was given a little more time than the rest. However, due to this, Issei had been neglecting the other, and felt bad. So, for now, he was paying attention to them, and Rias was on her own.

Said woman was doing some needed work before she could do anything else. However, as she finished signing a paper, her eyes were suddenly, and she felt scales over her head.

"Hello Kaa," said Rias.

"Hello Riasssssssss," said Kaa.

Rias' eyes were then let free, and she saw a 30 ft long Rock Python from India. Only this one, was from the underworld. When Rias was a young girl, she had wondered off, and got into trouble. Kaa was close by, and saved her from harm. After that, Kaa had been a good friend to Rias. As the years went on, Kaa had been developing something more for Rias. See, his kind was special to the others. His was a fully male species, and no females. So, they took humans, demons, angels, and fallen angels to be their mates. And Kaa had come of age to mate.

"What brings you here?" asked Rias.

"I have come to help you," said Kaa.

"If you mean Riser, he's been dealt with."

Rias then explained about Issei, and how they had been dating for a few weeks now. Kaa seemed to have missed his chance. To take her willingly. Now, he would have to be dirty.

"Oh, I sssssssssee," said Kaa, "Well, I'm happy for you. If there is anything that you need help with, I'm here for you."

"Thank you Kaa," said Rias, "I hope you find a mate. I had been looking at your species, and have seen you've come of age."

"Well," said Kaa, "Have you ssssssssseen everything?"

"Other than your age, and your record sizes, nothing much."

"Well, let me ssssssshare you a ssssssssssecret."

At that moment, Kaa's eyes started spiraling into a rainbow of colors, and Rias started to feel relaxed a bit. Kaa's species also had hypnotic powers that helped relax their targest, and make them submit to them, weather it's prey, or mates.

"My kind is fully male. No femalesssssssss at all. But, not all issssssss lost."

Rias had grown to trust Kaa, and was not fighting back at all. Rias' mind was soon under Kaa's control. Kaa held Rias' head in his tail, moving her around the room.

"Now," said Kaa, "I wisssssssh for you, to do something for me, before I take you away."

"T-T-Take me away?"

"Yesssssss, free you of all ressssssponsibilities."

"B-B-B-But me, friends, family, Issei-"

"SSSSSSSSSSSSSSSSSHHHH," said Kaa, "You don't need any of them. You only need the colorssssssssssss."

"I only need the colors," said Rias.

"Now," said Kaa, "I mussssst confessss, my dear. I have had my eyes on you for a few yearsssssssss now, to asssssssk you to be my mate."

"Y-Your mate?" asked Rias.

"Yessssssss," said Kaa, "my kind take humanssss, angelssss, fallen angelssss, and demonssssss, to be our matesssssssssss."

"But, why me?"

"Why not you?" asked Kaa.

Kaa then put something in Rias' mouth. She was taken back, and was slowly aroused by the motions Kaa was doing. If she was not hypnotized, Rias would have shocked Kaa with a spell, and scold him for his actions. However, she was submitting well.

Kaa then started to grope Rias' breasts and ass with his coils. Rias was feeling wet, and Kaa continued with his actions.

At that moment, Rias felt a liquid shoot into her mouth, and it didn't take long for her to realize what Kaa just did. She swallowed every drop, with some of it leaking out of her mouth. Kaa removed himself, and asked, "Now, how wassssss that, dear Riassssssss?"

"It was spectacular!" said Rias, "Pleassssssssse, do more!"

"I will, if you sssssssurrender to me, and be my mate."

"Yes, I surrender to you! Just please, take me some more!"

Kaa then said, "Well, my dear, you won't be needing thosssssse clothes."

Rias nodded, and unbuttoned her blouse. Then, she removed it, revealing her bra, with it covering a small amount of her cleavage. She then wiggled out of her skirt, swinging her hips like a dance. Rias kicked off she shoes, and pulled off her socks, throwing them to the side. She then spun around, and slipped off her panties, showing off her well rounded buttox. Finally, she unclapsed her bra, and giggled her breasts for Kaa, who's eyes went wide, and his body straightened out with a *BOING*

Kaa then howled, and smacked his head on the desk, before getting a hold of himself. Kaa then stopped, and said, "SSSSSSSSorry. Jusssssssst exxxxxxxxcited isssssss alll."

Kaa then said, "Now, repeat after me: you are my mate."

"I am your mate," repeated Rias.

Kaa started coiling around her ankles, pinning her legs together.

"You live only to bear our children."

"I live only to bear our children."

Kaa's coils made it to Rias' hips, and pinned her arms to her sides.

"You will give up your ressssponiblities, and ssssssssssurrender to me."

"I will give up my responibilities and surrender to you."

Kaa's coils went up further, and Kaa skipped Rias' massive breasts.

"Do you take thissssssss snake to be your wonderful mate?"

"Yes, I do-*ULP!*"

Kaa wrapped around Rias' neck, making her gulp, as a loud *PING* was heard inside her head. Now, Rias bore a very silly smile, and her eyes were a spiral of colors, never fading. Kaa then said, "You may kisssss, the bride."

Kaa and Rias then kissed, and the two were very passionate about it. Kaa then broke the kiss, and said, "Now, come with me, my dear."

Kaa lead Rias out the window, with her cocooned, with only her head, breasts and feet sticking out. He closed the window, turning to the reader, and winked.

Just then, Kaa heard a noise behind him, and turned to see a woman with purple hair, and thong like piece covering little of her body, thigh high boots, and wings the same color as her hair.

"Raynare," said Kaa.

"Hello Kaa," said Raynare, "I see you got her."

"Yesssss," hissed Kaa, "Now, release them!"

Raynare then summoned a portal, and out came a snake, longer then Kaa, black scales, and a stripe pattern rather than spots, with a woman who had nothing on, yellow eyes, and brown hair.

"KAA!" cried the two, and they held the snake close to them.

"Mother, Father," said Kaa, "I'm glad you are alright."

"Now, hand her over," said Raynare.

Kaa looked at Raynare in disgust, and said, "You said that she would be mine as long as she was gone!"

"Things change," said Raynare, not seeming to care.

"Son, is this your mate?" asked the older snake.

"Yes father," said Kaa, "She is."

"Leave now, before I change my mind," said Raynare.

Raynare smiled, knowing she would finally get revenge on Rias and Issei.

"Well," said Raynare, "isn't this ironic? You were so high and mighty, yet now, you are nothing but a lowly bitch."

Raynare summoned a spear of light, and said, "Don't Worry. I'll take good care of Issei after you."

Just then, something went around Raynare's neck, and she dropped her spear, as the object coiled harder around her neck.

"SHE WILL NOT BE HARMED!" yelled Kaa, "THIS IS NOT THE CODE OF THE ANGELS! HELL, YOU ARE A PATHETIC EXCUSE OF A FALLEN ANGEL! THIS MINDLESS WAR IS POINTLESS TO CONTINUE!"

"We... We all must... make... sacrifices!" said Raynare, whimpering.

"Isssss that right?" hissed Kaa, "Then let me do my part, to make everything better."

With an audiable snap, Kaa broke the neck of the Fallen Angel, and twisted her head around, making sure she was dead then and there. Kaa then threw the body away, and headed to Rias, coiling her up again.

"Come my dear," said Kaa, "Meet my family."

Kaa and Rias headed into a portal, that took them to a large tree, full of snakes and women. Some snakes were about the same size as Kaa, others were smaller, and some were almost three times as long. Some had women in their coils, other women were just going about, playing with the children.

Kaa then said, "Attention, everyone! I have an announcement!"

Everyone gathered around Kaa, and he then said, "I have acquired a mate! Her name issssss Rias Gremory!"

Everyone cheered, and congradulated Kaa, as Kaa's father said, "Now, now, you all will get a chance to meet her. For now, my son and his new love need privacy!"

Everyone cheered, and a little snake with blue eyes came up, and said, "Hi Kaa! Is there a chance I could ever talk with my new Aunt?"

"Sssssssssoon Silver," said Kaa, "For now, we must ssssseal the union."

"Ew!" said Silver, "That's too much!"

Silver then headed off, and Kaa laughed, as he went to the tops of the tree. As he climbed up, there were snakes with their mates, all of them either having sex, or simply sleeping. Kaa headed to his special spot, to the very top. There, they got a good look at the sky, and smiled.

"I've alwayssssssss wanted to ssssssshow you thisssssss, Riassssssssss," said Kaa, leaning against her.

"It's beautiful Kaa," said Rias, as she sighed in bliss.

Kaa then started uncoiling Rias' legs, and freed them, letting them dangle in the air.

Kaa then looked at Rias, saying, "Ready?"

"Ready as I'll ever be," said Rias.

Then, Kaa slowly pushed into Rias' untouched holes, as she moaned in pleasure. Kaa then plunged into her, and Rias screamed as her virginity was taken from her. Kaa then thrusted in, feeling something trickle down his cocks. He then looked down, and saw blood.

"Oh, you were a virgin," said Kaa, "I'm sssssurprisssssed that Issssssssssei never went for it."

Rias then said, "I don't care right now! Just fuck me! Fuck me like the slave I am!"

Kaa then picked up the pace, and pounded harder into Rias. He then latched his mouth to one of Rias' breasts, and sucked the nipple. Rias moaned harder, her eyes rolling into her head. Kaa then went faster, and Rias started blushing mad! Soon, Kaa started to reach his climax. Kaa then unlatched from the breast, and went in to kiss Rias, who melted into it, moaning.

After that, Rias' pussy tightened around Kaa's cock, and she orgasmed, as Kaa did as well. Rias let out a loud scream, that made some birds nearby fly off. The baby batter mixed together, and one of her eggs got impregnated.

Kaa removed himself, and wrapped Rias up once more, with the woman having a happy smile on her face, and eyes fully colored.

Just then, a voice said, "Kaa! There you are!"

Kaa's father and mother, the latter all coiled up and hypnotized, were sticking out the leaves, and Kaa said, "Father! We could've been busy!"

"Sorry son," said Kaa's father, "Your mother just wanted to have some fun, and asked me to do this, so I thought we would check in on you two."

"Okay, just next time, say something before coming up please!"

"Okay," said Kaa's father, as the family descended down, and Kaa and Rias giving the parents privacy.

At that moment, Akeno came in, and saw Rias' clothes on the floor. Issei had come back with Asia, and saw the body of Raynare in the bushes, and called the rest of the Peerage. However, there was no sign or trace of Rias that they could find. They searched all over the underworld, and over wrold, but nothing turned up. So, after three years, they gave up, and declared Rias dead. They all morned for her loss, but none more than Issei. If he had just spent equel time with all his Harem, this might not have happened.

However, Rias was alive, and now a happy mother of six. All with brown scales, red spots, and either blue or yellow eyes. Rias' eyes were still a rainbow spiral, but she was under control, and trusted to wonder without escaping. Each night, they would have sex, and pleasure each other in so many ways. The children were playing with the others, and Kaa and Rias watched from the side. Rias was coiled up, with Kaa next to her, thinking about how far they had come.

"I'll always love Kaa," said Rias, looking at her mate.

"I will alwayssssss love you too, Riasssssss," said Kaa, as they kissed.
