Masturbation Is Good for Mental Health

I stared at the floating window in disbelief.

I read the quest description again, hoping I had misread it. But no, it was exactly as it appeared.

"What the actual fuck? He's never jerked off even after becoming an adult?"

It was something I couldn't even imagine. Even if his body wasn't in the best condition, Arwen was still the young master of the Reinhardt family—the empire's sword. Noble ladies, village maidens, mansion maids... there should've been women throwing themselves at him left and right. Yet he was still a virgin?

"Did Isabel and Cordelia interfere or something?"

After the previous head of the family—Arwen's father—passed away, the position of family head had been left vacant. Isabel, who was thoroughly keeping Arwen in check to seize control of the Reinhardt family, would never allow any bitch aiming for the young master to get close to him.

"Yeah, that's entirely possible."

On top of that, this poor young master apparently didn't even know the joy of masturbation. I had no idea what kind of life he'd been living before I possessed him.

"First ejaculation, huh..."

I couldn't even remember when mine had been. The quest said to help with his first ejaculation, but it basically meant I had to jerk him off. Getting a masturbation quest right after possessing an adult game was ridiculous, but for now I had no choice but to follow through.

"Let's just get this over with."

The door was firmly shut. Still, just to be safe, I walked over and pressed my ear against it. Not a single sound came from outside.

"Good. This should be safe enough."

It was a little unsettling that there wasn't a lock on the door, but there was nothing I could do about it.

"There's nothing more humiliating than getting caught masturbating."

Even if this was a game, I didn't want to feel the kind of shame that came with being thrown naked into a dumpster.

"Getting caught by both mom and dad at the same time was fucking traumatic..."

Recalling a past I didn't want to talk about, I pulled down my pants and underwear in one swift motion. The imposing cock I'd glimpsed earlier sprang into view. Even knowing it was mine now, the sheer weight of the thing hanging there was intimidating.

The cool morning air of the room tickled my shaft. Through the half-open window came fresh air that couldn't be compared to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the stuffy mornings of Seoul. Now it was time to fill that air with the lewd scent of night-blooming flowers.

"Shall we begin?"

I ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠brought my right hand to my cock. It was a shame there wasn't any lube, but it couldn't be helped.

"Not like there's any porn here anyway."

But I did have one thing that God had given fairly to all humans: imagination.

"They say imagination fap is good for mental health too."

Rationalizing it that way, I decided on the target of my imagination fap. There was only one person who came to mind anyway.

Cordelia Reinhardt. Arwen's half-sister, the girl I'd just met.

Some might call me a beast for using my own half-sister—who shared half my blood—as masturbation material. But...

"Who cares? Those bitches tried to kill me!"

Besides, the game I'd possessed was an erotic one. In a world full of every perverted fetish imaginable, fucking your half-sister was well within the realm of normal.

I closed my eyes and focused, filling my mind with lewd thoughts about Cordelia. The image of her from earlier gradually became clearer.

Cordelia, a noble lady who had shamelessly shown off her thighs. Just imagining those plump thighs jiggling as she walked toward me was enough to send blood rushing to my cock.

Soon, a scene as vivid as actual porn began playing in my head.

'Whatever. Whether you took the medicine or not has nothing to do with me.'

Unlike the silence I'd given her earlier, this time I spoke clearly.

'Watch your language when speaking to your brother.'

'Kyaa?!'

I roughly grabbed Cordelia's hand, threw her onto the bed, and pulled down her pants.

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

'W-what are you doing?!'

I could perfectly picture the panic on her face as she stared at my cock.

'Shut your mouth.'

Even though it was just my imagination, I could feel the veins in my neck bulging. I pressed down on both her shoulders.

'Spread them.'

'N-nooo!'

I grabbed the stubbornly resisting Cordelia's thighs and forcibly spread her legs. Never mind that Arwen's frail arms shouldn't have that kind of strength—it's just imagination, who cares?

Between her spread legs, I could see red lace panties. Of course I'd never actually seen Cordelia's underwear. It was just something my imagination had created.

'Wearing panties like this when coming to see your brother? You must really want to get fucked by my cock, huh?'

'What are you saying? Have you lost your mind?'

'Shut up!'

When I grabbed her panties, Cordelia's hips twitched.

'Stay still if you don't want to die.'

'Wait! Don't take them o—'

I ignored her and pulled off her underwear, revealing Cordelia's pussy. It was probably just a generic pussy shape my brain had borrowed from one of the thousands of porn videos I'd watched.

'Hic... sob, don't look... please stop!'

Cordelia cried out in shame and embarrassment, but I had no intention of stopping. I immediately pushed my cock into her hole.

'I'm putting it in, Cordelia.'

'No! Please... aaah!'

Without any foreplay, a moan burst from Cordelia's lips as my cock penetrated her.

'Ugh, hic...'

I slowly moved my hips, savoring the way her pussy trembled from the pain. Her inner walls brushed against my shaft. Of course, in reality it was just Arwen's skinny hand stroking ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠my cock, but until I opened my eyes, this wasn't masturbation—it was me raping Cordelia.

'Haaang... haaht, aaaaaah♡♡'

Cordelia was moaning like a whore on her half-brother's cock.

'All that pretending to be refined, and you're nothing but a lewd bitch.'

'Ahht♡ N-no I'm not!'

'Oh really? Look how wet your pussy is. It's clinging to your brother's cock and won't let go.'

'Haaht, that's... haaaang♡ B-because you forced...'

'Still lying, huh? Looks like this naughty little sister needs to be punished.'

"Nooooo!"

The urge to cum was building in my cock. It was time to finish.

'I'm about to cum, Cordelia.'

'What? N-no! Haa... haa... Please, haaht, just not inside... aaaaaaaaaah♡~'

Along with Cordelia's scream echoing in my head, my cock began to ejaculate. The feeling of a passage that had been blocked by foreign matter suddenly opening wide. If I'd possessed a martial arts novel instead, would opening my meridians feel like this?

"Kuuuuurgh, that's the stuff."

With a shout like some middle-aged man drinking makgeolli in broad daylight, my semen shot out vigorously. Arwen's semen, which had been building up for over ten years, poured out like a waterfall.

I'd ejaculated hundreds of times back when I was Byeon Tae-sung, but Arwen's first ejaculation felt so refreshing that it made me forget all my previous experiences.

"Huuu, it's done."

When I looked around, the floor was covered in a sea of thick, clumpy white semen. Naturally, the room was filled with a fishy smell strong enough to make my eyes sting.

"This part is always the worst."

Everyone would agree. The hardest part of jerking off is choosing the material, and the second hardest is the cleanup.

Of course I couldn't just leave it like this, so I had to clean it up. But my trusty roll of toilet paper was nowhere to be seen.

"Should I just put on a thick face and ask a maid to clean it?"

The Reinhardt family obviously had servants working in the mansion.

"No way. They'd definitely treat me like a crazy degenerate."

Rumors would spread among the mansion staff that the young master had created a swimming pool of semen in his room the moment he woke up. In a situation where I desperately needed even one ally, I couldn't afford to alienate people over something like this.

"Yeah, I guess I'll have to clean it myself... what choice do I have..."

I was just starting to regret not preparing something to clean with beforehand when I heard a cheerful ding-dong sound, like a cafe order bell. Immediately after, a notification window appeared announcing the quest completion and stat increase.

A satisfied smile spread across my face.

"Just as I thought."

As soon as I finished masturbating, my Stamina stat had gone up by 1.

"So sexual activity increases the Stamina stat."

The first quest had been a tutorial to teach the player that very fact. From this, I could roughly guess what I needed to do during the one week I'd be staying in the mansion.

One: Have lots of sex.

Two: Raise my Stamina stat.

Three: Gain exclusive skills and traits thanks to the [Protagonist of an Erotic Game] characteristic.

And finally: Get stronger.

Of course, it didn't mean getting stronger in combat, but sexually stronger. Still, getting stronger was getting stronger.

I was a little doubtful whether raising only my Stamina stat would let me defeat Masha, but...

"No, I probably don't need to worry about that."

My voice was filled with confidence. Just like how the first quest had changed from bare-handed exercise to masturbation, the battle with Masha had most likely been changed into some other 19+ event as well.

In other words, all I had to do was keep doing lewd things diligently, and when the time came, fuck Masha. With such a clean plan decided, I clapped my hands together sharply.

"Perfect. Simple enough."

The only thing left now was to clean up the room, which looked like the set of some bukkake porn video. The pool of semen I'd forgotten about for a moment was glistening in the sunlight. The fishy smell had faded, but that was just because my nose had gone numb. Anyone else who smelled it would probably faint in horror.

"Goddamn it, how am I supposed to clean all this up?"

I crossed my arms and closed my eyes, tilting my head this way and that as I pondered, but no solution came to mind. That's when I heard the familiar ding sound again, and the second quest arrived.

"Already? Fuck, can't I at least get a break?"

Grumbling about the tight schedule, I checked the next quest.

The name written in the quest title—Raibel—was one I knew very well. Raibel, the maid of the Reinhardt mansion. She was a heroine you could meet in the early stages of the game. She was also the only heroine in the Reinhardt mansion, which had become a den of villainesses.

"Still, 'make the innocent Raibel your woman'..."

The wording gave off serious vibes of a city thug trying to seduce a country girl who'd just moved to town.

"Grope her tits once and get a blowjob once, huh."

It looked easy but was actually quite difficult. No matter how close the relationship between master and maid was, you couldn't just suddenly say "show me your tits" or "suck me off," could you?

"Looks like it's time for my SS-rank trait to shine."

The effects of the [Protagonist of an Erotic Game] trait:

These effects were incredibly convenient when it came to seducing women. It was practically cheating. All I had to do now was use this trait to slowly conquer Raibel.

"I wonder how long it'll take? Two days? For now, let's start by meeting her today..."

I was carefully planning out my strategy to conquer Raibel when I suddenly heard movement outside the room.

"What the—?"

Before I could even react, the presence had already reached the door.

"Shit... wait, don't open it!"

Despite my warning, the door opened mercilessly. At the sound of the latch clicking, my heart sank.

"Sniff sniff, Young Master?"

A woman sniffing like a dog. Whether by God's prank or the developer's, the person who opened the door and appeared was none other than Raibel—the very target of the quest.

"Young Master, are you okay? There's a suspicious smell coming from the room..."

Raibel trailed off and froze. Her gaze was fixed on my lower body. Specifically, on my cock, which was still hanging out completely exposed.

"This is..."

I was so flustered that words wouldn't come out properly. I quickly turned my body so she couldn't see and hurriedly pulled up my pants.

'You stupid idiot, you should've put your pants on right after finishing!'

Of course, even if I'd been wearing pants, the pool of semen would've given away that I'd been masturbating. Either way, it was too late to regret it now.

Raibel was backing away with a bright red face, as if she'd seen something she shouldn't have. Her attitude made it obvious she was completely disgusted with me.

"U-um... I-I'm sorry..."

'Fuck... I ruined it before I even got started.'

I wanted to save and load right then and there, but unfortunately that function no longer existed.
