B is for [B]utt Sex

"Can you please stop staring, it is making me quite uncomfortable," Sona said, blushing slightly as Issei continued to check out her butt, bent over the wooden desk.

"It's a good butt," he admitted. "Probably the best feature on you."

"I do not know whether that was a compliment or an insult to the rest of my form." Sona gave him a cold glare.

"Take it as a compliment." Issei ran his hands over the curve of her butt, touching and prodding the soft cheeks with his index finger. "Do you shave back here?" Her entire backside was as smooth as a babies butt, with her asshole and pussy free of any sort of hair.

Sona didn't look at him, but judging by her expression, she did. That was all fine with him, shaved or not. Issei wasn't much of a stickler on body hair, however it all came down to personal preference.

He groped the surface of her butt, feeling the softness of it and how utterly firm it was in his hands. Issei sank his fingers into the soft, flawless flesh that belonged to a person he had once admired before all this power.

Taking one step further, Issei's eyes traveled to Sona's tight rosebud. Her asshole, to be frank. Poking it with his finger, Sona let out a cute little squeak as he poked and prodded her backside.

Noticing the still topless Rias at the corner of the room, Issei decided to bring the redhead into this instead of ignoring her. What's better than one girl? Two girls of course.

"Hey Rias, how about you help lube up Sona here," Issei said.

"Sure," Rias said perkily, under the effects of the room. "Why?"

"Why?" Issei showed off his dick to her, still hard even after Sona's godlike handjob. "I'm about to, you know?"

"No I don't know," Rias said.

"He's going to fuck me in the ass, Rias," Sona said, looking away to avoid catching a glimpse of his cock.

"Nicely said." Issei lifted his hand and delivered a smack to Sona's right ass cheek, watching it jiggle with a grin on his face. His own boner became harder when Sona let out a tiny little moan from his ministrations.

Rias approached the both of them and got behind Sona, readying herself. Rias got on her knees, running her hands along Sona's toned thighs and pulled apart her firm buttocks.

Putting a finger in her mouth, Rias made sure her index finger was well lubricated and with no time to waste, Rias inserted her finger into Sona's tight asshole.

"Oh!" Sona gasped out loud.

"What? Too sudden?" Rias asked, stopping for a minute.

"N-no, you can keep going." Sona's face was becoming more flushed, breathing much more heavier than before. This was probably the first time something on this level has happened to her.

And so she did, after Rias inserted her finger into her asshole, she began moving her finger in and out. The previous lubrication made it so that her index finger practically flew in and out her asshole.

Sona's hips wriggled and shook as Rias's fingers continued adding pressure. One finger became two, then became three. Moans and groans came out of Sona's mouth as she felt Rias's finger stretch out her tight hole.

"I think that's enough lubrication." Issei dismissed Rias. "Go masturbate in the corner or something."

Issei got behind Sona, grabbing her hips with his hands. He guided his penis to the tip of her asshole, still slick with Rias's spit.

Poking it a bit, Issei could feel Sona's warm asshole on his cock. Said girl shivered a little, letting out a small squeak as his cock touched the entrance of her rosebud.

Thanking the gods above, Issei slowly pushed himself into Sona. The first push was tight, tighter than he had ever imagined.

"Damn," Issei cursed out, trying his hardest to push his cock into her ass but the tightness of which was overbearing. The lube helped out a bit as slowly, inch by inch of his cock slipped in and Issei could freely brag and say that he was in the Student Council President's ass.

Sona groaned out in pain, shaking as Issei smacked her ass. The whole experience had been nothing but pain for her, the size of Issei's cock being too large for her petite frame.

His cock was fully in her ass by now, and he had to respect the many pornstars that did anal. It wasn't as easy as they had made it out to be.

For starters, it was tight as hell, even with the abundance of lube provided by Rias. Granted, she did use saliva instead of actual lube, but still.

The feeling of your cock being stuck inside a warm and tight hole was heavenly, and Issei cried tears of joy at the feeling.

Seeing as he had fit his entire cock inside Sona's ass, Issei decided to speed it up. Balls deep in her ass, Issei pumped his hips back and forth.

Sona let out a few moans of pain as Issei sped up his thrusting, she grabbed onto the table to steady herself as her insides were burning with arousal.

Slapping her firm ass, Issei brought his arousal to new heights. He smacked it and groped it, upping his speed twofold. Sona's ass seemingly swallowed his ass with every thrust, the inner muscles of her asshole squeezing his cock every few seconds bringing him ever closer to orgasm.

The harsh slapping of her ass was echoed throughout the whole room, with Rias fingering her pussy in the corner attributing to a portion of the noise. It was a wonder that nobody had wandered in yet.

"You're such a slut," Issei groaned out, leaning forward and groping Sona's tits as he continued thrusting deeper and deeper into her. "An anal alut."

"N-n-no!" Sona moaned out, the pleasure overwhelming her. She had begun thrusting her ass back, making sure that Issei's cock reached deeper and deeper inside of her.

He could get used to this, the view of Sona's firm ass jiggling with every move he did. He then began to slap her ass more and more, the white flesh turning red from his repeated slaps.

"More!" Sona groaned out, tears running down her face as her pussy dripped arousal. "Pound me!"

Issei growled out one final time, his cock pulsing wildly. Sona moaned out loud as she felt his cum rushing deep into her bowels, rope and rope of hot liquid entering her asshole at supersonic speed.

With a grunt, he pulled out of Sona's ass, his cock still twitching as ropes of cum hit her back. Stroking his cock, Issei unleashed several more ropes of hot cum on her ass and pussy lips.

"Ara ara." The door of the Student Council President's room flipped open as a figure walked out, hands crossed underneath her large bosom. "When I heard the President was busy, I didn't know it was this busy."
