Back to ecchi though,

He felt great, he had managed to get around his mana problem by basically poaching the earth resource, human stuff.

Issei felt so satisfied of his achievements of being able to use this, he want to celebrate.

And what better way then to fuck with one of the most popular girl outdoors inside the school.

The girl on that is on her knees was the one that escorted Issei to the Occult a few days ago, Yumi who is buck naked in Kuoh, where there are students are walking by on the open field while she is in the nude surrounded by trees and grass.

Her clothes are neatly placed beside the tree while she is giving Issei a tittyjob, there her left breast can be seen with a letter that wrote her Owner's name.

Yumi felt embarrassed at she doing now, shamelessly naked out in the open giving service to her Owner, but this is her Owner's orders so she must oblige.

Issei, felt a bliss, touching the boobs of any girl felt like a pipe dream no matter how much he wish it back then. Now he is sucking tits left and right on whoever he wants. And he is having his dick rub by the breast of a true princess.

"Is this good? I kinda need to go to my club," Yumi asked, rubbing her breast up and down to simulate the meat rod that is between them.

"Just a minute, after this is done," Issei grab those bountiful boobs ads squeeze them harder between his dick. Finally, after a few strokes he finally let out his cum onto her face.

"Oh sorry, that just felt good." Issei cheekily apologize.

"That's ok, I am your property, so it would be obvious that you would use me to satisfy your needs, especially with your reputation." Yumi replied, though she did tried to rub the fluid off, Issei happily love to help by using his water magic to wash it off.

"Ahh, that was the best," Yumi's breast is truly heavenly. With that, he feel like he should let her leave now to continue with her work, probably her Devil work(maybe he should try to summon her in his room).

Yes, she is a devil, it's always hard to remember that she, the Occult and Student council are Devil's. On the surface, she is known as the princess but she in reality she is the knight to her King Rias(which is odd thing to say but chess piece terminology).

She is also his type f girl, an Onee-san.

Issei look at the Kuoh princess to admire her naked body once again before she leaves, her breast isn't as big as Rias nor Keno, but it definitely has a good shape. a perfect curvature that felt equally soft and firm, her body is quite a balance of slim and curvy.

And her ass, damn, his dick is hard again by just looking at it.

Though that's it for now, they have things to do, well Issei simply have girls to grope, but Yumi seems to be in a hurry. So it would be his respect to let her continue on with her day.

Only a nanoseconds last, and his lust came back strong.

"Bend over,"

"Huh?"

"I want you to place you hand on that tree and show your ass to me," Issei ordered, his dick sprang forth again, it seems the titjob was not enough to calm it down.

Yumi blush red but followed as she presented her ass to Issei. He look at those ass, he can see the lips and even the puckered hole that is hidden between those cheeks, he never peg himself as an assman to be honest but it's not like he didn't appreciate it.

Issei grab both of those cheeks as his palms dig into it, he prepares rubbing his revive erection between her buttocks. One would think he is preparing to take her virginity, but surprisingly not. Not because of some moral's, oh no, he had probably sunken low enough to actually do it. But for a practical reason actually.

While his power allowed practical mind control, it doesn't really give him birth control.

He heard of a magic that allowed for safe sex, but sadly Issei couldn't find it since apparently Devil's rarely use it. Considering their now low population and low birth rates, their not to keen on teaching the youngsters something like contraception.

Unfortunate, but he can still use the ass, which is why he is positioning himself near the above. Yumi can feel the tip pressing between her second hole.

"Right there..." She whispered, her answers came in with a thrust and an anal. She moan as a wave of unknown pleasure came onto her.

God damn is this tight. Never thought the princess has a tight asshole, he kept thrusting wildly while grabbing her hips, causing Yumi's breast to flop with each movement.

The knight is trying her best to surpress the moan lest she made a rumor of a ghost sound near the forest.

One, two, three, thirteen, the thrust was so good that Issei let out all of his cum this time. Overflowing her butt with it. She let out a bit of the moan as her anus was filled with cum.

Afterwards, Issei felt that he was finally satisfied and goes back.

"Ah, another day hmm?" Issei notices a white-haired loli near him as he goes outside the forest. The loli, known as Koneko stared at him.

"Ummm, Hi?" Issei waved,.

"Pervert," to which Koneko simply walk away with leaving one word

"Ah, guess she knows,"
