Bonus Chapter.

Pa! Pa! Pa!
"Ahnn! Ahnn! Harder! Yusuke! Harder!" Suspended in the air by a pink rope binding her tight, Akeno's moans echoed through the room. Her hands were tied high above her head, her legs folded against her thighs, her body restrained in a proper turtle tie that left her arching helplessly as every cry rang out louder than the last.
Pa!
"Stupid cunt, did I just hear you ordering me?!" Behind her, Yusuke raised his hand and brought it down against her large ass, the sharp slap landing as he thrust his waist forward with rough force. His cock pressed hard against the tight wall of her asshole before forcing its way into her backdoor, driving her body forward with the impact.
"Yes! I mean, sorry master~!" Akeno moaned as she felt the sting of his slap and the rough pounding that followed. Her unfocused eyes stared at the ceiling above her, her tongue hanging out vulgarly as drool dripped down her chin. Her wide spread legs trembled faintly, and beneath her, the carpet bore a large dark patch thanks to the waterfall spilling freely from her pussy.
Her large breasts, the current wet dreams of every male in Kuoh Academy, swayed violently under the impact of Yusuke's brutal thrusts. Two pink clips clamped tightly onto her stiff nipples, tugging and bouncing with every rough movement.
In the past, whenever she saw Yusuke abusing that masochist Aika and watched the depraved expression on her face, twisted with ecstasy and bliss, Akeno always wondered if it truly felt that good. A strange sensation lingered deep inside her, one that kept pressing and urging her, whispering insistently for her to try that feeling at least once.
So after giving it some thought, she decided to try it. Anyway, even if she was an S, who said she could not be an M and an S at the same time, right? She wanted to try everything with her man, Yusuke. He was a wonderful man, one who would accept every part of her without complaint.
"Shit! You are tighter than before! Slutty masochist, you really are enjoying this!" Yusuke grabbed her soft butt cheeks and spread them apart, staring as her asshole swallowed his cock all the way to the hilt, almost like it was welcoming him in. When he tried to pull back, her fleshy walls clamped down on him like a vice, locking him in a relentless tug of war.
"Ahn! This is bad~! If you keep treating me like this, I might really lose my mind! I feel like I am cumming!" Akeno's head grew hazier by the second, her thoughts melting under the pleasure. Squirt had been shooting nonstop from the moment they started fucking, and it showed no sign of stopping as her body shook and gave in completely.
"You cuming? Aren't you already cuming since earlier? Who knows how many times you have been orgasming, masochistic pig! I feel embarrassed for your parents for giving birth to such a failure of a living being." Yusuke let go of her butt and slid his hands up to her breasts, tugging hard on the clippers. Her body arched instantly as she orgasmed once more, a sharp cry tearing from her throat. He clicked his tongue in open disdain. "Tsk, tsk, you really cum again, hopeless pain addict."
[You've gotten used to this; you've been trained thoroughly by Aika.] The system suddenly commented.
'What do you mean by being trained by her?! If anyone is training anyone, it's obviously me training her!' Yusuke's expression darkened, and he subconsciously tugged at Akeno's nipple harder. He felt insulted by the word 'trained.' Did he look like some Shota being trained by his mother's friend?!
"Agh! Why are you getting tighter?! Shit! I'm cumming!" Yusuke suddenly felt Akeno clenching harder around his cock, her fleshy walls wriggling on their own, caressing him and urging him to release his jizz.
Knock! Knock!
Suddenly, a knock at the door interrupted the duo, or rather, the trio. "Yusuke-sama, it's time for supper," Grayfia's voice called from outside.
"Senpai, it's me, open the door," followed by Koneko's voice.
"Shit! Why right now?!" Because Haki consumed spiritual energy, and because he didn't expect anyone stupid enough to attack the Gremory Castle, Yusuke didn't bother using his Haki at this moment.
To think that someone would come at this critical moment, just as he was about to reply, Akeno's voice rang out. "Ignore them, let's finish first! Cum inside me! I want your thick milk inside me!" She turned her head back to him, eyes shaped like hearts and overflowing with lust and love, her lips curling into a lewd, inviting grin.
Pa! Pa! Pa
"Fuck it!" Her words and expression nearly made Yusuke lose all reason. Without hesitation, he resumed his thrusts. Everyone knew his relationship with Akeno; he had nothing to fear from Koneko, and Grayfia wasn't a yandere. Even if she was displeased, she could go and fuck herself.
Even Rias, the person concerned, couldn't do a damn thing to him, so why should he care about Grayfia's opinion in the first place?
Worst comes to worst, he'd just bolt and return to his place in the human world.
"So rough! I feel like I'm cumming again even though it was just a moment ago! This is incredible! Yusuke! I love you! Fuck me harder! I love the way you make love to me!" Akeno's moans grew louder, as if she wanted them to hear every sound. Her love juices spurted more freely as she climaxed once more.
"Ugh! I'm cumming too!" Yusuke pulled her close, pressing his body against hers and kissing her neck as he poured his spunk into her ass.
Bang!
As the two neared their nirvana, the door was flung open with a violent crash, the lock shattering under the force. The scene inside the room became fully visible to Grayfia and Koneko.
"Senpai!" Koneko's cheeks flamed red. Her first instinct was to selectively ignore Akeno's body, focusing entirely on Yusuke's naked form and committing it to her mental hard drive.
"You two..." Grayfia's gaze locked onto them, her eyes cold as ice. More specifically, she glared at Akeno. How dare she do something like this to Her man?! Just like every yandere, she never blamed her man for what had happened; instead, she directed all her ire at the others.
"Haahn! Haahn! I came so much~!" Akeno didn't seem to notice the two intruders, still wearing a ridiculously lewd ahegao face. She whispered between moans, faintly gasping as copious amounts of spunk slowly dripped from her asshole.
"Who told you to come in?!" Yusuke shot the last of his load, pulling his cock from Akeno and glaring at Grayfia. He was starting to grow annoyed with her. He hated how she always made him feel stressed and even afraid, a feeling that only irritated him further. On top of that, her earlier actions, nearly breaking his hand, only deepened his dislike for her.
His cold remark snapped Grayfia back to her senses. She stared at his dangling cock for a few seconds before regaining her composure. With an expressionless face, she said, "Excuse me for my rudeness. It is time for supper. The family head and Sirzechs-sama are waiting for you. Please get ready." With that, she closed the door.
Crack!
The moment the door closed, the wooden handle she had been holding cracked into tiny pieces that fell to the floor. Without bothering to speak to Koneko, she turned and left silently.
'Unforgivable! Unforgivable! Unforgivable! Yusuke is mine! Mine!' Walking down the long hallways, Grayfia roared in her mind. Her frosty expression grew colder than a ten-thousand-year-old glacier. Earlier, it had only been sheer willpower that kept her from shredding Akeno to pieces. No one knew how much restraint she had used to hold herself back. 'I can't wait any longer!'
Thinking of her plan, ready to be executed at any moment, calmed her raging fury. Recalling the image of Yusuke's naked body and his precious tool on full display, her cheeks flushed red, and her eyes took on a purple heart shape. "As expected of my Yusuke. His body is perfect, and his… his cock is even better than I dreamed of!"
"Ahn! I can't wait!"
'Senpai, he looks even more lewd than before… I think my panties got wet again, nya~!' Koneko stood frozen in front of the closed door for a long while. Finally, she turned and walked back to her room, no longer planning to go to supper. The scene she had just witnessed had ignited her mating instincts. Right now, she couldn't wait to get back to her place and practice some water jutsu.
This wasn't her first time seeing Yusuke banging his women, so her reaction wasn't nearly as dramatic as Grayfia's. In fact, she had peeped on him a few times at school, sometimes on the rooftop or in empty classrooms.
'If only I could do it with senpai too~!'
...
"Ara ara~! Grayfia-san seems really upset." Watching Yusuke untie her, Akeno laughed seductively. She didn't seem to care about what had happened earlier at all, and even had the leisure to tease him by licking his face with her long, wet tongue.
"She's starting to get on my nerves, always trying to ruin the fun. She should care about her own family instead of meddling in Rias's affairs. It's not like she's her mother or anything." Once the rope was untied, Yusuke lifted Akeno into his arms, helping her to her feet. Perhaps because she had come so much, her legs were weak, and she clung to him for support.
"Actually, Grayfia-san is usually gentle and understanding. Perhaps she's acting like this because she sees Rias as her real sister," Akeno said, speaking on Grayfia's behalf as her hands roamed Yusuke's naked body, tracing his muscular form. She could never get tired or bored with this.
'Perhaps she's right. I'll try to give her another chance… Speaking of sisters, I heard that Sona's sister is an extreme siscon. Just thinking about how I should deal with her gives me a headache… Let's hope I don't meet her anytime soon.' Silently, Yusuke used his Telekinesis to pick up a towel and began wiping her body, removing sweat, drool, and other fluids.
His movements were gentle and attentive. When he finished wiping her body, he helped her onto the bed, brushing her disheveled hair as he spoke, "Hopefully, Rias's father and brother will be as easygoing as her mother."
"Don't worry, the two of them aren't like other snobbish nobles. They seem to approve of you as well," Akeno said, her eyes closed and a satisfied smile on her lips as she enjoyed his attentive care.
