A Cheat-Grade Fleshlight

Sujin's ass was a milking machine. It might have even outperformed her pussy. Less than twenty-four hours after I'd taken her virginity, she'd already thrown her anal virginity away too.

What kind of absurd succubus was this woman? Had she been born a few centuries earlier, a body like hers could have brought a nation to its knees and no one would have been surprised. Was the thing bouncing on top of me even Sujin at all — or a monster wearing her face?

Squelch! Squelch! Squelch! Squelch! Squelch!

Flesh slapped against flesh, and the obscene friction hammered my heart like a train whistle. A satisfaction so complete it felt like my chest would burst, a pleasure I couldn't control, wrapped around my entire body. I'd already blown one thick load, and my cock showed not the slightest sign of dying.

Sujin had already hit what looked like a peak climax of her own, yet her body hadn't slowed in ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the slightest. That was a Hunter's physique for you.

"Haaahn~! Anh~! Anh~♥ Haaaahn~! Haaaahn~♥ Pulling it in and out…! I love it so much!"

The sheer contradiction of her taking pleasure from a hole meant for waste stoked an even hotter fire in my chest. I could barely hold a thought together. Just how filthy was this legendary hole? If I commercialized her ass as an onahole, getting filthy rich would be a piece of cake. Her pussy and her ass were both SSS-rank.

Ghhk. Fuck, I need to pace myself — a cheat-tier pussy AND a cheat-tier ass? She's a succubus that shapeshifted into a human, isn't she!? There's no other way she could have a broken asshole like this!

Plap! Plap! Plap! Plap! Plap!

With every powerful grind of Sujin's hips, my soul leaked out of me. In the end I dumped two more loads inside her. Even with a reinforced body, that was my limit. And since each ejaculation had been twice as heavy as a normal jerk-off session, it was the equivalent of coming six times.

Sujin, who'd been using my cock as a masturbation toy and whipping her hips like a madwoman, hit her third climax and collapsed on top of me as if she'd passed out. I cracked an eye open. Only the whites of hers were showing.

This was more serious than I'd thought. Drool ran in a thick thread from her mouth. Damn it, I wanted to drink it. I could have substituted Sujin's spit for water and never gotten tired of it.

Pblurt! Plop!

My cock was still buried in her ass. A vulgar little sound accompanied a rise of white foam from her hole — my cum, churned without mercy into lather. My seed seeped out of her in lazy, wriggling rivulets. It was a scene of staggering filth. I wanted to photograph it with my phone, but I was pinned underneath her and could barely move. I had the Watching Eye capture every frame instead.

"She's completely wrecked. Hah… this blew my expectations out of the water. I figured the training would take a week at the very least…"

I'd underestimated Sujin's libido. Or maybe this wasn't simply her libido at all — maybe it was the power of Power of Sex. Power of Sex amplified the pleasure of the act itself. The thing that had turned her into this kind of nymphomaniac was, without a doubt, my ability.

"Looking at it like this, it's terrifying."

It really was a frightening power. Used properly, stacking wealth and influence with it would be as easy as breathing. Even if that was getting ahead of myself — at the very least, bedding women would be effortless. The woman currently passed out from climax on top of me was living proof.

"Sujin tasted incredible, but I wonder if other women will taste this good too."

Needless to say, I had not the slightest intention of stopping at Sujin.

Having a power like this and using it on only one woman would be an unforgivable waste. It wasn't just about my own pleasure, either. To properly exploit the effect that made me stronger every time I had sex, I needed to take a lot of women. Virgins, if at all possible.

"Mmmnhhh…!"

Sujin let out a moan on top of me and rolled her hips. My cock, still spearing her ass, was sucked elastically deeper by the motion.

"Ah~ nngh~♥"

Her moan of pure delight made me click my tongue. She really was an outrageous slut. A woman this filthy, I had no choice but to take responsibility for. Anyone without Power of Sex would never be able to satisfy her anyway.

Sujin was already past the point where masturbation could do it for her. Even now, she was using my cock to get herself off in her sleep. For all I knew, she was ravaging me in her dreams too.

"Whew. If I'm going to keep up with a cheat-grade living onahole like this, I'm going to need a lot of prep. First things first — let's see how much stronger I've gotten."

I checked the notification windows that had surfaced in my mind. So Sujin's ass had been virgin too, just as I'd thought. Taking anal virginity apparently granted a first-experience bonus of its own. Fine by me.

I'd picked up a title as well. The name, though, was pretty cheeky. Backdoor, translated literally, meant the rear entrance. In games it usually referred to a play of looping around to hit the enemy's main base from behind. I pulled up the title's effect.

The effect was the anal version of Virgin Hunter. Same as that title, it boosted the efficiency of first-experience bonuses. There was a skill-bestowal clause too, though I wasn't sure what to make of that yet. I'd find out as I took more women.

Next I checked my stats. With an anal first-experience bonus in play, I expected a considerable jump — and I was not disappointed.

Every stat had gone up by ten. Once a stat crossed 100, each additional point cost ten bonus points — which meant, converted, I'd effectively gained 400 points.

"The stats went up plenty, but it's still a little disappointing. If four loads is enough to knock me out, building a harem is going to be a real problem. I need to boost my stamina."

Investing in sex was not a loss. I got stronger through sex, after all. If anything, it was an investment in the future.

Stamina was probably a component of Strength. I shut my eyes and dumped 600 points into it. Strength climbed from 120 to 180 — a gain of sixty. My bonus points, which had been 688, dropped to 88. Watching that number shrink made my heart clench.

"Don't think of it as a waste. It's an investment in the future!"

I felt the stamina increase immediately. A body that had been running on fumes surged back to life.

"Hoooooh…! Hoooooh…!"

Sujin, who'd ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠been using me as a mattress, suddenly seemed to weigh less. That was the Strength talking — she felt light. She hadn't been particularly heavy to begin with, but still.

"Good. As for the rest…. Huh? The skill tab is glowing."

It looked like it was begging to be pressed. I tapped it. The skill window opened, and I could see the changes at a glance.

Every skill that had been Lv.1 had risen to Lv.2, and the effects had shifted with the levels. Time Acceleration's duration had gone from ten seconds to twenty. Mental Resistance's status-condition resistance had climbed from 10% to 20%. Pregnancy Control had even gained the ability to raise conception chance.

"When skill levels go up, the effects get stronger too. The power of Power of Sex. It's ridiculous."

Through sex I could reinforce not only my stats but my skills. How broken was this ability? Granted, this was only a jump from level one to two, so I couldn't map the efficiency with any precision yet — but I had more than enough to grasp how fraudulent the power was.

And as much as I'd grown, Sujin would have grown too. She'd offered me both her virginities and raked in a fat first-experience bonus for it. She might already be at the level where she could become a Dungeon Hunter. I'd have to keep a close watch on her room with the Watching Eye.

"Nnhhh~♪"

With Sujin still on top of me, spilling sweet little moans at whatever she was doing in her dreams, I drifted off as well.
