It's time to reward!

Yachiho began to undress against her will.

"Hey, what's happening?"

"Himari hasn't told you, has she? This is the price of the **** power. After the transformation is undone, the master will have to reward the **** based on the task that they've done."

"Ehhh... Pervert! Don't tell me you did... 'this' to my sister?"

Yuuki blushed. I did it to your mother too.

Yachiho felt embarrassed when she was naked, but she became terrified when her hands extended uncontrollably toward Yuuki's clothes: "What kind of reward is this?"

"... I think the reward is sexual intercourse."

"...You beast! If you dare to touch me, I... I'll kill you!"

“I can stay my hand,” He told her, “but if I don't take the reward, it won't end.”

Yachiho gave it some thought, her eyes peering at him. After a pause, she asked, “You don't sound like you're eager. Am I unattractive?”

“You’re a gorgeous woman,” He said without missing a beat. It was true at a glance, "But I want to respect your wish."

"... Damn it. Okay, do it quickly and we'll go to save Himari as soon as possible."

Yachiho wasn’t the bustiest woman around, but Yuuki thought that her breasts were well-defined. Then his gaze moved down to her thick ass cheeks and bare, exposed slit. He couldn’t help but notice she was soaking wet.

"Hey, are you distracted? Just take your... your... filthy thing out and do it!"

Yuuki sighed and pulled his pants down. With one hand on her ass, he slowly shoved his cock into her well-lubricated pussy. He’d never fucked a woman before, but he thought it was… surprisingly tight. He continued to push in until his entire length sunk inside her. She could take it all.

At this distance, they could feel the warmth of each other's breath. The natural scent Yachiho gave off was like vanilla crossed with strawberry, and Yuuki, in a single moment when his horny teenage brain took full control, pressed his lips on Yachiho's. After a second of hesitation, she kissed him back with the same passion.

They continued to breathe life into each other, growing warmer as our bodies heated up and the kisses got harder. The tongues danced, gliding over each other slickly and tasting one another. To her own surprise, Yachiho found out that she was an amazing kisser.

Yuuki kept slamming his cock faster and faster into her mature, lubricated cunt. He’d never been so eager to fuck someone in his life. He wished that it would go on forever – but of course, it's impossible. Several minutes later, he felt that he was about to cum. He needed to warn her: "Oh… oh… Yachiho, I’m going to cum any second, now. Where do you want it?"

A few drops of sweat glistened on her forehead. She shouted in panic:

"Pull out! Please... do it outside!"

"Sure!" Yuuki slowly pulled backward, most of his energy focused on not cumming. Suddenly, Yachiho's legs wrapped around his hips. Not only did they stop him from pulling out, but they also pulled back, making his cock go deeper into her.

"Are you sure you want me to pull out?" He felt a new rush of energy as if his instinct asked him to creampie the woman. Her pussy kept squeezing his cock tightly. It could explode at any moment.

"I... my body moves on its own! It must be a part of this damned reward!"

Yachiho's train of thought moved like crazy: We are fucking barebacked. I'm not on any kind of birth control. When did I have my last period...

"I can't keep it any longer! Tell me what to do!’

‘I... I don't know! Do not cum whatsoever… AH! FUCK!"

Yachiho forgot that she was also on the verge of cumming. Being thrust hard by a large cock pushed her over the edge, and her love juice spurted out like a flood. That orgasm sealed the deal – it made her cervix open, leaving her womb unprotected.

"I’m cumming! Ngh…" Yuuki groaned, leaning forward and pressing his weight down onto Yachiho. It’s impossible to describe how amazing it felt to creampie a woman who really wanted you. That was a far cry from masturbating or fucking with a condom. His semen surged through his cock, and sprayed into his mate’s unprotected cunt like a hose of hot water. Loads after loads of his sperm filled her baby room, looking for a target.

After the climax passed, they lay beside each other, breathing heavily. Until...

"Hey, why do you still not pull out?"

"I... I can't! It's you who is locking me with your legs."

"Why would I..." Yachiho suddenly realized she was still unable to move her body freely.

What? Why hasn't the reward ended yet?

Then she felt a tickling in her abdomen. It should be biologically impossible, but somehow she knew it was her ovaries releasing an egg.

Oh crap! I am ovulating!

It's quite late, but Yachiho finally realized what the reward actually was. It's not "mating", it's "breeding". A man she barely knew was impregnating her and she was powerless to stop it.

She continued to gaze at Yuuki's face as her egg traveled across her fallopian tube, thinking about what should she do next. Only when the egg began to be attacked by his army of swimmers that she reached the Acceptance stage.

"Are you in love with Himari?"

"What... eh, no. I'm more like her personal cook."

Good, at least I'm not stealing my sister's lover.

At that moment, a lucky little sperm finally invaded her egg. Yachiho could feel the zygote implanting into her uterus. Then her strange sense stopped and she found that she could move again.
