Editing Shinmai Maou no Keiyakusha:Volume 7 Chapter 2 (section)

===Part 9===

That instant, Mio felt Basara’s penis twitch in between the valley of her breasts. Following that was the sensation of a hot flow spreading across her breasts.

''…Oh my, it’s incredible…''

She could clearly feel him convulsing while still immersed in Mio’s deep cleavage. While she felt a sense of accomplishment at having been able to please Basara, Mio saw that her own deep cleavage was close to being submerged in a bottomless pool of cloudy white liquid — she couldn’t help shivering all over as that pool of viscous, thick liquid began to trickle out of her cleavage, and fall to the ground with pitter-patter sound drops. At the same time, Basara’s penis slowly began to slide out of her cleavage—

''…Ah…''

Moreover, it was still bulging as much as it was before. Mio swallowed, and then moved her mouth towards it. This time, Basara didn’t stop Mio from doing it.

“Haa…mmm…chu.”

Mio finally put Basara’s penis into her mouth. The scent of Basara’s semen instantly scattered in her mouth, fully taking away all of Mio’s rationality; but that didn’t matter, as her rationality would only serve to hinder her own obedience towards Basara — so, when she began to carefully wrap around and cleanse Basara, when she swallowed the semen that filled her mouth, she cast aside the last strand of her rationality.

“Ah…mmm, chu…mmfuu, haa…chuu…mmm!”

Mio sat down with her legs in a seiza-like position, and used every ounce of her ability to please Basara with her mouth. After her saliva-covered tongue wrapped around it, she sucked hardly on it with chuu chuu noises, and then used her hands to gently massage it; soon after, Basara began to thrust his hips back and forth slowly, indicating that his pleasure was on the verge of a climax — this caused Mio’s excitement to intensify further, and she began to match Basara’s movements by moving her head back and forth.

“Mmm…chuu…haa, mmm…chuu, wuu…luu…haa, mmm, fuu…chuu…mmm! Chuu! Mmm♥”

While she was obsessed with sucking Basara’s penis with her mouth, in the instant that a vast amount of flowing hot semen burst out, a sweet climax also caused Mio’s entire body to tense up. It turned out that when Basara ejaculated inside of her mouth, a lot also dripped down towards her breasts. The sudden pleasure was so strong that she could not resist — but she was absolutely obedient to Basara right now, so even though her buttocks trembled to the point that her feminine juices soaked through her panties, she did not bite Basara, she just desperately propelled her throat, and swallowed everything that Basara gave her. However, Sheera’s drug caused Basara to produce a shocking amount…until Mio almost choked, Basara slowly withdrew from Mio’s mouth while still enveloped by the edges of Mio’s lips.

“Mmm! Mmm! …Chuu, ah — ah ♥”

At the same time that his tip came out, Basara’s white liquid spayed onto Mio’s face, frightening her such that she fell backwards. Basara then left the edge of the bathtub, but not to support her, but instead to move over and press down on her.

''…Eh…?''

Mio couldn’t help but stare in awe at Basara’s face in front of her, and she then became aware of what he wanted to do. Basara’s eyes had been ignited with a burning fire of male desire as he stared down at her with passion, and with a tone of voice which was hard to reject, he said

“Just underneath the underwear — can I?”

The moment that she understood the meaning of that sentence, Mio took a deep breath. What Basara meant, was that he wanted to satisfy his lustful desire — to insert it underneath her underwear to avoid crossing the final line.

''…N-No…!''

If she did something like that right now, she didn’t know what would happen. The final line that absolutely couldn’t be crossed would become blurred. Even though Mio thought that — when she thought about the fact that Basara had become so excited by her that he cast aside his reason and craved her even more, she felt so happy that she trembled, and so she swallowed—

“!…Mmm…”

Even though she knew that it wasn’t something she should do, she clutched the back of her knees with trembling hands to spread her legs apart, and exposed her private area in front of Basara. Her hot and wet feminine juices was soaked her underwear, but the contour underneath was also clearly visible, and it emitted bursts of obscene heat.

“Okay, onii-chan — come.”

Mio maintained that posture, and then coquettishly said that she was ready for Basara, after which Basara immediately — inserted his penis little by little from the opening into her underwear which was absolutely soaked all the way through.

“……I’m going in.”

Basara whispered, and then pushed into the deepest point in an instant.

“! —Fuwaaaaaaaaaa!”

Naruse Mio fiercely climaxed just because of this thrust. This was caused by Basara brushing past her opening…while at the same time kneading her sensitive breasts roughly.

“Ah…! …Mmm! Haa…ah…ah ♥”

 

Coming from the sensation of him being underneath her underwear was a climax on a completely different level from the past, causing her to even to forget how to breathe; it was a moment of anguish mixed with joy. While Basara slowly moved his hips, he pushed his penis against her underwear, all the way until Mio’s belly button before retracting, and then—

“! ——”

Wait — although Mio wanted to say that, she didn’t make a sound.

“—I’m going to move.”

The moment after Basara announced that, he began to intensely massage her breasts and rub against her private area, engraving into her again and again a countless number times — no,  she wanted to count them, but she was unable to count the number of her innumerable climaxes.
