No one could get between Machina and Mutsuki, but it looked like they would have a hard time filling the space between them.
“I’m not holding back now.”
“Hwah!”
Lucia embraced Mutsuki from behind. He had not gotten hard again after cumming so much, but it still surprised Mutsuki to feel the cum-sticky penis against his butt.
“Ahn!”
He pushed his hips forward in surprise, causing Machina to moan as he thrust hard against her womb.
Her weight shifted further forward while back on all fours…which meant she squashed Ange even more.
“Hee hee hee¦ Kiss me now, Mutsuki-kun.”
“Eh? Nh, mh…mphh.”
Lucia was a sub but loved to tease his partner, so he could control everyone else here as long as he was not being teased at the moment. He turned Mutsuki’s head toward him while pushing his still-flaccid thing between Mutsuki’s butt cheeks.
He kissed Mutsuki as if showing off to Machina who had been too embarrassed to do it herself. He started off using tongue as if to demonstrate his own superiority.
Mutsuki had trouble being teased mentally, so he was at the boy’s mercy. He could only receive that tongue that seemed to be sucking out the lingering sweetness he was experiencing with Machina.
“Nh, nhh…kh, Lucia-kun…not so rough.”
And once he accepted it, he was exposed to Lucia’s mind-blowing tongue technique.
“Ah, ahh, so big, nh, it’s getting bigger.”
His hips reacted to the pleasure of that soft tongue attacking within his mouth, so he stirred up Machina inside.
His dick swelled out even more and throbbed while stimulating all the surrounding flesh. It seemed rude, but this stimulation from someone else was making him stimulate Machina further.
“Ahh, ah, nh.”
Of course, the girl did not find it rude, but the fact remained that he was picking up speed within her.
Her hips reacted by wiggling around and sexily shaking her large butt.
Watching the heart-shaped flesh wiggle around was entertaining, but the real problem was the stimulation this provided to his penis. The flesh itself transformed from the movement of her butt, stirring up the male thing within.
The boy reacted to the rhythm he himself had started within her and his hips began to move from the pleasure.
His shaft and her flesh had felt joined together as one, but now they separated.
“Nh, ahhhhhh!”
Machina cried out.
He had already cummed once, giving him some relief, but she had not had that luxury, so the pleasure from each stroke was much greater for her. Her body trembled as she came close to climaxing from that alone and she moaned from each and every thrust.
The invader was as hard as steel, but it bent flexibly since it was not fixed at the base. It hit every last part of her internal flesh and attacked the pleasure nerves packed within every one of her folds.
“Ahh, hh.”
Her cries of pleasure seduced the male no matter what form they took, so Mutsuki began thrusting harder against that attractive ass while the demon continued to suck at his mouth.
“Ahhn, ahh, so rough, ahhhh.”
The pleasure of each thrust made Machina cry out.
“Ahh.”
More heat transferred into her each and every time.
Ange mostly did not know how to react to the scene. They were not allies, but she still trusted that classmate to remain calm at all times, yet here she was revealing such a sexual side to herself. The usual expressionless face had loosened with pleasure, the always taciturn mouth was releasing moans, and Ange had to watch it all right in front of her since the girl was on all fours above her.
Ange could feel the incredible pounding Machina was receiving by how the other girl’s breasts would jiggle against her.
And Ange herself had been on the receiving end of that before, so she was reminded of how it felt. She still had her skirt to cover things, but she could feel heat filling her crotch.
She looked up at Mutsuki to see him still being kissed by Lucia.
The demon boy noticed her gaze and grinned as if another idea had occurred to him.
“Hey, hey, Ibekusa. That girl is feeling left out, so how about you kiss her?”
“What!?”
The malice in Lucia’s grin made it clear this was only meant to occupy those two so he could have Mutsuki’s lips to himself.
But before she could snap back at him, Machina did as suggested. Her flushed face made it clear she was experiencing too much pleasure to think straight, plus she had always been an obedient girl. It helped that Ange did look like she felt left out.
“Understood.”
“Eh? Wait, Ibekusa. I-”
“…?”
“~~~~~~~~?”
She sucked at Ange’s lips just like she would at Mutsuki’s.
Ange blinked in surprise, but it did not occur to her to bite or to shove Machina away. The other girl’s mouth tasted dizzyingly sweet and its softness soon prevented her mind from functioning properly.
It helped that Machina looked incredibly sexual lying on top of her and rubbing down against her. Her smooth skin felt nice against Ange’s similar elegant skin.
The soft weight of her incredible bust was also overwhelming. Ange had seen Mutsuki look frustratingly delighted when Micha or Schwartz pressed their enormous breasts against him, but now she understood why.
“Open your mouth.”
“S-stop this…hey, ahn.”
Her words were meaningless. She opened her mouth as told and she gave up on closing it again when that would mean biting the tongue that had entered her mouth. In fact, she offered up her own tongue to tangle with Machina’s.
“Nh, nh.”
“Ah…mh…nhh, Ibekusa…your lips are so sweet.”
“Nhh…taste them as much as you want.”
The two girls kissed just as passionately as the two boys.
A sticky sound came from their mouths and the girl on the bottom finally gulped with some of her red hair plastered to her throat. Machina seemed more dutiful in how she went about it, but Ange was surprisingly aggressive. The large breasts pressed against her seemed to bother her, so she shifted her own body to rub her chest against them.
Lucia grinned at successfully dividing the kissing up along gender lines.
“Nh…Ibekusa-san, let me join.”
“Huh?”
But the scene of the two girls making out caught Mutsuki’s interest, so he left Lucia’s lips and leaned forward against Machina’s back.
With him there, Machina of course gave him priority, so she stopped kissing Ange.
“Nh.”
She kissed him over her shoulder.
He was still thrusting into her and their union squeezed tight while their kiss naturally dragged on.
“Oh, come on!”
Lucia was not happy about this. He leaned over on Mutsuki’s back and forcibly turned the other boy toward him.
Mutsuki did as asked and began another gay kiss.
“Ahn…Ibekusa…ah.”
“Ah…yes.”
Meanwhile, Ange placed her arms around Machina’s neck to resume a sweet lesbian kiss.
But not everything was back to the way it was before. Machina’s focus had been redirected toward Mutsuki’s penis and the different positions of their bodies allowed it to push even deeper inside her.
The pressure on her womb was a constant presence on her mind and the level of pleasure rose once more. She moaned loud into Ange’s mouth and Ange gulped down her sweet breath and saliva.
“…”
When Mutsuki felt the harder sensation of the cervix, he recalled what he had been told earlier that day.
Based on the data taken from Lucya…
“Ibekusa-san, this womb is supposed to have my child, isn’t it?”
“Nh…y-yes.”
“So it belongs to me, doesn’t it?”
“Y-yes, ahh, my womb…belongs to you.”
He could hear the arousal in her voice. The tremors of orgasm were beginning.
“P-please impregnate me. I want to have your child.”
“…”
He wrapped his arms around her slender waist.
