Despite being underneath him, she became the one **ing him.

She expertly kept clenching her butt muscles in effortless movements, milking his dick, and sucking out his seed in small bursts, drawing out his orgasm from the almost depleted balls.

Zach’s whole body rampaged as his dick continued to swell inside her sweet ass.

She closed her eyes even tighter, feeling it stalking around the edges, and willed it to cum.

The incredibly tight walls of her rectum squeezed tightly on Zach’s cock and made him feel as if he was on the verge of giving up.

Consoling himself with the knowledge that no man could survive long in a hole this tight, he slipped his other hand under her waist, holding her tightly in both arms, he arched his naked butt out, and slammed into her ass with the full force of his body behind it.

Her ass cheeks bounced back defiantly as they defended against the suddenly powerful attack with the inbuilt shock absorbers.

Zach repeatedly slammed his lower body into her ass, but each thrust was faster and stronger than the last time. He didn’t want to give Luna a moment’s respite to clench his member any longer.

The slurping sound of his wet cock, sliding in and out of her tight ass, rode on the heels of the tap-tap sounds of his crotch slapping against her bouncing ass.

He gripped her even tightly with both hands, burying his head next to her whimpering mouth, and felt her thighs spread even wider to accommodate his aggressive invasion.

Her eyes rolled, feeling every inch of it in her bowels.

She took control and began to rub against his dick, wiggling beneath him, prodding his stiff rod along the walls of her rectum that ignited sparks in her brain.

Luna’s body trembled all of a sudden when she felt the throbbing dick inside her reach its bursting point. She couldn’t have been more familiar with Zach’s spurting limit. As such she seized all movements and gave one last clench with her butt muscles to squeeze his dick from all sides.

Zach felt his soul leave his body after this point and he couldn’t help but release everything he had been holding back with the sheer force of his will.

On the wide bed, fully naked, and gasping like a slut, Luna let him fill her up, thoroughly enjoying the feel of the throbbing of his cock in her ass hole and the sticky liquid that painted her ass in white.

She twitched and whimpered under the weight of Zach’s body on top of her, but she was far too invested in the fulfilment of her lustful desires to understand what was going on around her.

She was gasping for breath like a sprinter after a hundred-meter sprint, but Zach couldn’t have been more stable.

The situation was always the exact opposite in the past. It had always been him who was left panting and struggling for a breath after a heated session with Luna. Given her racial advantage in such matters, Zach had never felt like he had won in their nightly battles because he was always drained out completely by the little succubus.

But now he barely felt anything. He was still bursting with energy just as he had been at the beginning of the nightly session. It was as if the sperm in his balls couldn’t be used up even if he filled up all of Luna’s holes one by one.

Luna wanted to take some time to rest before going again but Zach seemed to be thinking along a different track entirely. He wasn’t the least bit tired and couldn’t help but think back to the heavenly feeling of his dick inside her tight ass. He wanted to experience it once again.

Zach turned her over on her chest so that her ass was facing towards the ceiling. He pulled on her waist and Luna inadvertently raised her ass slightly to give him the perfect angle of penetration.

He hoisted his mast into her asshole once again. His dick slipped right into the deepest region thanks to his residual cum acting as the lubricant for his member.

A powerless moan escaped her lips, and it was further muffled by the pillow that was underneath her face.

Despite being lost in pleasure, she still had the sanity to ask Zach to rest for a bit before continuing.

“Aren’t you tired? Why don’t we take a rest first?” pleaded Luna in a low groaning voice.

“Surprisingly, I don’t feel tired at all, not even the least bit. It’s like we have yet to begin. I wonder why that is?”

Zach truly couldn’t understand what had changed since the last time he had sex. It had never been like this. After coming this many times, he would usually be sprawled across the bed with no knowledge of his surroundings. But this time was different. He not only felt full of energy but was also fully capable of continuing for any length of time. It was not natural at all.

The host does not need to be shocked. You have absorbed a lot of energy from Diana. She is an overwhelming reservoir of energy, and it is your luck that you managed to secure her for yourself before anyone else. It has helped strengthen your body.

“So, does that mean that I have unlimited supply of semen in my balls?” asked Zach excitedly as he tried to prod the limits of his body with the help of the system.

The system was usually unresponsive to all his questions. Now that it had taken the initiative to answer his question, it could only mean that it was willing to answer him for some reason.

Therefore, Zach didn’t hold back on his questions and asked them all without hesitation.

The excess energy that I helped you absorb while you were unconscious is still stored inside your body and has improved your bodily functions. That’s why you don’t feel tired even after having coitus for as long as you did. Also, the fact that there is no end to your sperm is only because that excess energy is assisting you in keeping your body in an optimal state at all times. It will replenish the depleted stock automatically so as to keep you in a perfect condition.

“You mean that this isn’t just limited to sex?” Zach wanted to understand the kind of benefits he was entitled to thanks to the energy he extracted from Diana.

Of course, its use isn’t that limited. Otherwise, the name of void body wouldn’t be worth anything at all. It increases the rate of recovery of your body by several times. Since your sperm count is also considered a part of your body, it has an exceptional recovery rate and can be continuously recovered as long as there is enough energy in your body.

“So, it isn’t endless after all?”

Zach was somewhat depressed at the revelation after all, the endless semen wasn’t real. It was just a byproduct of the excessive energy in his body.

No, it is.

“What do you mean? You just said that it depends on the energy in my body.”

Then do you think that these little bits of sexual acts are enough to deplete those energy reservoirs in your body? You are severely underestimating the talent that a void body has. Don’t think about these things at the moment. You will surely understand what I am telling you in the future.

The system went into the background once again and no matter how much Zach tried to involve it in a conversation, there was no reply or any kind of system message.

As such Zach put all his attention back into pounding Luna without mercy. The poor succubus had no choice but to comply even though her whole body was sensitive from their previous session. Her body twitched and tingled but she neither had the strength nor the willingness to stop Zach from making love to her in a beastly manner.

Zach took this opportunity to do whatever he wanted with her. Although he let her rest by doing all the work, it was far from what she needed. Her body was already out of it. It was twitching crazily and was so sensitive that she experienced orgasm even with the slightest brush against her skin.

While Luna was trying to reassemble herself, Zach went wild as if he had no intention to stop until the end of the world.

Luna couldn’t handle the stimulation of her body and passed out while her whole body spasmed, giving Zach a sadistic pleasure, something he never knew he would come to like. Zach forgot everything else and pounded away like a well-oiled piston engine.

Exactly ten minutes later, Luna’s mountainous chest struck out as she awoke with a deep inhalation that seemed to have filled her empty lungs with oxygen. The air filled her with a breath of life as if she was rising from the dead.

Her small head bobbed upwards, meeting Zach’s piercing eyes above her as if staring deep into her soul.

Surprise crept across the poor succubus’ face as she felt extremely embarrassed that she had passed out amidst sex with her master even though she had been the one to insist on more.

“No…did I…did I actually fall asleep?” she wondered in disbelief “…that can’t be…”

Reading her mind, Zach spoke out loud.

“Yes. . .” he said “You went out for a minute there. . .”

He laughed softly and he didn’t stop what he was doing despite the obvious disbelief written all over the succubus’ face.
