Training the Second Monster

It was 8 o'clock on a Saturday morning. Yuji was still holding Rinko close to his chest as she slept.

He peered at Rinko's face. As she slept with an innocent expression, she looked adorable and charming.

Yuji took out his smartphone to check Rinko's status. Rinko's affection level was already at 92, set to "Lovey-Dovey" relationship.

This was the result of continuous sexual activity with Rinko from 7:00 PM the previous day until 3:00 AM today. Considering that it had taken almost a week to raise Yukina's affection to the same level, it seemed that not only their compatibility but also Yuji's sexual skills had improved.

Currently, their levels were as follows:

Yuji at 23,

Yuki (Yukina) at 18,

Rinko at 12.

Yuji had already collected a (Love) Cupid's Arrows from fucking Rinko, and he had also performed "Monster Enhancement" on her before she fell asleep from exhaustion.

Yuji left Rinko and headed to the bathroom to take a shower. They were both covered in body fluids after numerous encounters. When he finished showering and returned to the room, he found Rinko sitting on the couch.

"Good morning."

"Good morning. It seems you slept well. Take a shower."

"Yes... Thank you."

While Rinko took her shower, Yuji tidied up the bed and prepared a simple breakfast.

When Rinko emerged from the shower, she was wearing one of Yuji's shirts. She wasn't wearing pants, and she had no underwear on.

Yuji planned to make Rinko return home today, and he intended to invite Yukina for sex on the following Sunday.

Rinko then would head here directly after her band's self-practice session. Yuji planned to talk to her and Yukina at that time.

In a quite twisted romance relationship or lovey-dovey setting might make her hesitate about the presence of other women, Yuji believed that under his "Complete Obedience" ability, Rinko and Yukina would accept it.

Rinko hugs Yuji and kisses him. Her attitude is unusual for someone so shy.

Alert: (Using "Monster Enhancement" over Rinko, she'll start calling him by his real name, the same goes for Yukina)

"Yuji-san, I love you, I love you so much."

As she said this, Rinko lifted Yuji's shirt, kissed his body, and spread saliva on it, almost as if marking territory.

With a quite cute and sad expression, Rinko said "It's sad that we have to part for a while starting today. So, let's continue our night together even more..."

"Rinko you're such a lewd girl who is very interested in erotic things, aren't you?"

"That's...!"

"It's okay, I don't hate you. In fact, I love naughty girls like Rinko."

When Yuji said that, Rinko smiled and looked radiant.

"Well then, let's enjoy ourselves until you leave."

"Yes!"

Rinko voluntarily sucked Yuji's cock into her mouth. She gently stroked the shaft with her right hand and sensually caressed his scrotum with her left hand. Her technique might not have been perfect, but her sincerity to make Yuji feel good was apparent.

While Rinko is sucking his dick, Yuji thinks about having Yukina teach Rinko the blowjob material, and has Rinko sit on top of him in cowgirl position.

Even though Rinko was still wearing her clothes. Her erect nipples were visibly pushing against the fabric. Also since she wasn't wearing any panties, her saliva was dripping from her intimate area.

Yuji rubbed his cock against the wide opening pussy between Rinko's legs. The underside of his shaft stimulated her swollen clitoris, spreading pleasure throughout her body. Rinko's outstretched legs curled as she shivered and her mind was overwhelmed with euphoria. As Yuji's dick penetrated her, Rinko's brain was consumed by delightful sensations, leaving a vivid impression of the intense pleasure she was drowning in.

"Naaaaaaaaaaaaaaaaaaaaaaa!"

A sweet electric shock ran through her, and sparks flew across Rinko's head. Her consciousness burns brightly and she feels like she's about to jump, but the shock of thrusting deep inside her vagina doesn't allow her to do so easily.

Despite the fact that her shirt had come undone, exposing her breasts, she continued to move her hips without inhibition.

"Aaah, I'm cumming, I'm cumming, I'm cumming, haaaaaah!

Rinko moves her hips on her own while holding hands with Yuji. Actively participating in their passionate embrace quite active, she screams and moans out her love for Yuji, saying, ``I love you, I love you, I love you.''

When the overwhelming pleasure ran through Rinko's body, making her vision turn white, her swaying and enticing breasts, exposed through her open shirt, squirted a milky fluid. Rinko had started lactating.

When Rinko's body was filled with such pleasure that her eyes turned white, milky white liquid gushed out from her voluptuous breasts, which were exposed through her open shirt, squirted a milky fluid. Rinko had started lactating.

.

Apparently, when Rinko reaches the peak of sexual pleasure, her body naturally starts producing breast milk. Yuji learned this later when the lactation fetish was added to her preferences, likely due to the intense pleasure she experienced.

When he pulls out the meat shaft from Rinko's vagina, she holds it in her mouth wanting to give him a blowjob, intending to perform a cleanup fellatio.

The sensations gushing through his lower body made Yuji involuntarily moan. He caressed Rinko's head in a way similar to how one would pet a beloved pet, fills Rinko with a sense of euphoria, her eyes glistening with moisture, and love, while continuing her blowjob attentions. She appeared to be genuinely delighted.

"Lick… Ah, it smells so lewd... Chuu, slurp... Lick..."

"Oh, this is... pretty good. Keep it up!"

Yuji's dick has already regained its hardness, and Rinko is giving a blowjob not to clean it up, but to make him ejaculate again.

"Yuji, please. Please release your cum it in my mouth."

Rinko, with her flat body and low head, begged Yuji to fill her mouth up.

"Are you sure about this? I don't think it'll taste delicious."

"It's delicious. Because it's yours, Yuji-san."

"Really?"

"Yes."

Yuji decided that if she was going to go that far, he would do it and make her wish came true. This is something Yukina has already done. And she was so captivated by it that she even urges him to do it without asking for permission. Rinko might become like her too.

Despite her inexperience and clumsiness, it was clear that Rinko was trying her best to bring him to climax. Rinko placed her hand on Yuji's thigh.

"It's almost there, about to come..."

"Ubuu..."

Rinko nodded with Yuji's dick in her mouth, and her movements became more intense.

The movement of her head becomes faster, and the hand job by jerking the rod becomes faster as well. The tongue is moving furiously inside her mouth.

"I'm about to cum."

"Phew!"

Yuji ejaculated, holding Rinko's head, and released his semen from his cock.

"Eehh... Mmmphhhh!"

Rinko momentarily looked surprised but continued to hold his penis in her mouth, accepting the semen inside.

After the ejaculation was complete, she seemed to savor every last drop in a lewd manner, extending her tongue to slurp it up, wearing a lewd Ahegao expression that almost resembled a frog's.

"Mmmph... Mmmph..."

Rinko herself was excited and was breathing heavily. Once his dick came out of her mouth, a trickle of cloudy liquid dripped from the corner of her mouth.

Yuji looks at Rinko, whose mouth is puffing out as she soaks in the afterglow.

"You can spit it out if you want."

Then, Rinko sadly shook her head and refused.

"Are you sure? Then take your time and drink it slowly."

She nodded and, with her eyes closed, made an effort to swallow the semen, looking like she found it somewhat difficult.

Yuji hugged Rinko and praised her.

"Thank you for worrying about me... but it was surprisingly delicious, Yuji-sama."

Afterward, Yuji and Rinko continued to have sex continuously until she returned home at 6 PM. By that time, her Affection rating was at its maximum, and Yuji couldn't decide between the:

Crazy in Love,

Complete Obedience,

Setting but he chose "complete obedience". This was done to protect Yukina as well.

Before she left, both of them were again covered in sweat and bodily fluids, so they decided to take a shower. They thoroughly washed each other's bodies. Yuji also applied soap to Rinko's body and had her wash herself, enjoying the sensation as her breasts were rubbed with just the right amount of pressure, creating a blissful moment.
