Chapter 4

Did I get caught? Sure, I wouldn't score any urine voyeur coins this way, but screw the coins—I really wanted to see it. My sister's pristine white naked body. From those insanely aggressive tits down the slender waistline to the massive curve of her ass. She always bundled up tight, but it wasn't like she could hide something on that level. More focused than ever in my life, I carefully cracked open the bathroom door.

Creak. As I slowly eased the door open, bright light poured through the gap, stark against the dim laundry room. Open it too wide and I'd be busted for sure. I stopped just at the angle where the shower booth came into view. Through the narrow slit, there it was—my sister showering with the booth door closed, unlike me. Thick steam fogged the glass, blurring her nude form. It felt like watching a 144p video. And yet, even through the haze, the silhouette of her body was a goddamn work of art.

—Splash. Splash. Sounded like she was washing up. She lathered a shower puff and scrubbed everywhere—shoulders, arms, armpits, every nook of those massive tits. Then down to her legs, calves, thighs, ass, and ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠even her pussy. Me? I just slap on shampoo and body wash and call it a day. But Haena started some full-on treatment routine. As she shifted poses to reach every spot, she thrust that firm, huge ass toward me one moment, then stuck out those overwhelming tits while scrubbing her back the next. The steam hid the details, but that only fired up my imagination more. God, I wanted to fling the door wide and drink in the crystal-clear view, but I held back with everything I had. Breaking the door handle was supposed to enable urine peeps, not this—I hadn't anticipated it. Guess I needed to order anti-fog spray ASAP.

That's when she finished lathering and turned the shower back on.

—Splashhhh.

Just as she started rinsing off the suds—

Ting! The coin hit the floor louder than expected. 'Shit, did she hear?' My heart dropped. Great, new coin from shower voyeurism, but if Haena caught that sound... She was the classic cool beauty—aloof personality, strong likes and dislikes, and she'd call you out in that icy tone without hesitation. If she busted me peeping? My life was over on the spot.

I tried picking it up super quietly to avoid more noise, but then another coin dropped right on my hand.

Plop.

What the? Double drop? If I'd been slower on the first one, the second ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠would've clattered for sure—total dead giveaway. Two coins at once was nice, but my heart was pounding like mad. Scary as hell. A bunch of info windows popped up, but I dismissed them. Escape first.

I tiptoed out on my heels, slipped out of the laundry room, and bolted to my room.

"Phew..."

Time to check these coins. One was gray like the others, but the second was red.

First, the gray one.

Shower voyeur coin, obviously. More Psycho? Referencing that classic movie? Anyway, adds the "risk peeping on shower" option. Stats aren't bad...

Now the red one. I nearly yelled.

Heroine-exclusive coin, and +3 to Exposure Mania? But "Loves Exposure"—did she notice me peeping? Panic hit hard. Am I screwed? If relations tank and conquest stalls, it's game over. What if she storms my room yelling? Relationship ruined, conquest impossible, Demon Sister rips me apart? Headbutt the floor and beg? Tearful ass apology? My brain was a mess.

But staring at the coin, the worries evaporated like smoke. It was like the coin whispered, "I'll handle it all."

I fired up the computer to order anti-fog spray. While it booted, checked the notifications.

Whoa! Finally, Heroine Status Window. Checking Haena's right away.

What a mess. Especially that [Family Relation] trait—already a pain. Probably need Incest coins to counter it. And the hidden ??? trait. Explanations per stat would ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠help, but right now? Stats scream "long road ahead." Mom and Lea's were even worse—total resets. No base stats? Explains their conservative vibes despite those bodies. Tough conquest ahead.

Next window:

Jackpot. Shop wasn't items—it boosted my stats/skills. Exchange traded coins for shop gold. Skills like Golden Finger, Big Dick Owner—guy magnets. Magnifying Glass for curiosity. Pheromone Walker seemed OP. Newbie me: play safe. Ordered the anti-fog spray. Stored urgent coins, farmed Incest coins till dawn. Thankfully, Haena showed no sign of suspicion.

——Weekend morning. Nothing eventful—just farming, farming, farming.

"Son! Mom's ready."

Yebin called from the entryway. Our promised weekend jog. Dressed, I headed out.

"Me too."

Whoa, overkill? Mom's jog outfit was legendary. I'd hoped for tight leggings battling her massive tits, but nope—baggy student-era tracksuit thanks to zero Openness. Still, those tits stood out...

"Huff... huff..."

I'm dying! "Son! Tired already? Let's train harder from now on?"

Insanely, Mom wasn't winded at all. Self-care queen. Her stamina crushed mine. I'd fantasized watching her tits bounce, hearing exhausted moans... Bullshit—my gut jiggled, I was the one gasping. Gotta build stamina. Life reflection time. Fuck, should've used the treadmill.

Gasping up to her, she handed water. "Here, water."

"Huff... thanks... huff..."

"Weekends from now on, jog with Mom, got it?"

"Gulp... yes!"

Chugged and headed home.

Back home, Mom headed to the master bathroom. Peek opportunity soon. Missed a notif earlier from breathlessness. Tapped it.

Fuck yeah. Supports self-improvement? Thanks a ton. Max Stamina +1 ain't nothing.

Simpler than Heroine windows. Boost that 101 Stamina, and Mom's moans are inevitable? But no—lost control, raging boner again. Peek Mom's shower? Peered out—risky. Weekend, Haena and Lea home, prime spots to spot me heading to master. Too suspicious. Play safe till Openness/Lewdness rise. No fuckups.

Porn it is. Sat at PC. Lately, family panties/fantasies sufficed—no porn needed. But vanilla? No dice. Searched incest porn. Boom, instant horniness.

Stroke. Stroke. Stroke.

"Ahh! Sis!"

Splurt. Splurt.

Imagined blasting Haena's face, wiped up. But my door was ajar. And two coins on my thigh—one was Haena's.
