Chapter 49 Rock-chan
Edited by: Kanaa-senpai
Day 17 of the Tester Life. Morning. Room. Sanada Yakumo.
The sound of rustling woke me up.
I opened my eyes to find the spot beside me empty. Sayaka-san wasn’t in bed; I could feel her presence in the service room across the hall. She was likely maintaining my gear, practicing what I’d taught her yesterday. I figured she’d eventually crawl back in for a morning blowjob, so I stayed put, killing time by reflecting on yesterday’s haul.
Rock’s evolution was the big win. Having him as a reliable tank had already bumped our efficiency, and if I decked him out in proper gear, he’d be more than just a meat shield-he’d be a legitimate asset.
When we finished the crawl and returned to My Room, Sayaka-san was waiting at the door as usual. She practically tackled me with a hug the second I stepped inside. Behind us, the hallway was a mess of salty Students-half of them grumbling in envy, the other half frantically trying to stop their hot-headed buddies from charging back into the dungeon to prove something. I didn’t bother telling Sayaka-san to tone it down. Watching the Students’ reactions was half the fun.
After that, it was the usual routine: gear off, straight to the shower. I’d been wound pretty tight, so I took her from behind under the spray for the first round. Then, while we were soaking in the tub, I had her climb on top for the second.
Once I’d cleared my head, we had dinner and played some games. I was surprised when she asked to play an RPG-she’d said before she wasn’t into them, and this one was a dungeon crawler, of all things. It didn’t seem like the kind of game a girl like her would enjoy, but she was so serious about learning the ropes that we ended up playing way later than intended.
After the game and a single episode of a foreign drama, I hooked my phone up to the TV to show her some porn. Her face turned a spectacular shade of crimson. She was so damn cute like that that I ended up manhandling her breasts and clit while the video played, making her cum over and over. Eventually, I couldn’t handle her lewd little gasps anymore; I moved us to the sofa, where I made her give me a blowjob that ended with me painting the back of her throat.
While she was busy “cleaning up,” I carried Sayaka-san to the bedroom for a heavy breeding press. I followed that up with an ekiben¹-keeping it inside the whole time-and finished her off in cowgirl. By the time I’d emptied myself for the third time, she was a limp, quivering mess from the back-to-back orgasms. I told her I had to go settle the day’s accounts and headed to the living room.
Exchanging the Magic Stones² for cash felt good. The payout was better than the day before-solid proof that I was actually making progress. I picked up some gear for Rock and confirmed my balance had hit 500,000 DP. Then, it was Wall-Butt³ time.
The lead-off hitter was Freya, predictably.
Maybe she was still frustrated after Lanora cut in on her last night, because she was beaming at me through the display. She’s so honest and sweet it’s hard to believe she’s a demon. I told her straight up that I’d been lonely without her last night. It felt like Freya’s Infinite Tentacles were actually addictive; even my cock seemed to have missed her.
For some reason, Freya was incredibly sensitive today, hitting internal peaks one after another. Every time she clamped down, my knees nearly buckled, but I held on and enjoyed the waves of pleasure. My junk was practically screaming, This is it! This is the feeling! I can’t get enough of this! It felt incredible.
At the same time, it was a grim reminder: if I met her for real without a high enough Rank, she’d suck me dry and leave me for dead in a single night.
After Freya squeezed three rounds out of me, the next girl up was a terrified-looking teenager-maybe high school age. She had a red bob cut and looked like she was normally a spunky type, but her expression on the screen was dark and miserable. I felt a surge of annoyance at the students and teachers-just how badly are they treating these girls?-and I gently stroked her ass through the wall to calm her down.
I showed her a rhythm game to distract her, and once she looked interested, I let her have a turn. She used her tail to tap the buttons, looking genuinely happy. By the time her turn was up, she was all smiles. As a thank-you, she gave my cock a rub with her tail while I took her from behind, kneading her firm, hand-sized breasts until I blew my load. When the timer hit zero, she disappeared with a cheerful wave and a wag of her tail.
Feeling refreshed, I cleaned up, went back to the bedroom, and fell asleep while hugging Sayaka-san.
The sound of the bedroom door opening pulled me from my daydreams. Sayaka-san gently peeled back the duvet. I kept my eyes cracked just enough to see her strip out of her loungewear and kneel between my legs in just her underwear.
She slid my boxers down and buried her face in my crotch, her tongue tracing the curve of my balls before working its way up the shaft. She licked along the underside, then finally took the head into her mouth with a wet pop.
She started a rhythmic, pumping motion, her mouth slick with saliva as she made wet slurping sounds. I realized this was the technique I’d explained to her while we were watching the video yesterday. I was impressed by how fast she learned, but mostly I just let myself melt into the pleasure. She’d stop every now and then to tease the tip with her tongue before diving back in. I could feel the heat building in my gut.
”Guh… it’s coming!” I groaned.
Thick streams of semen fired into her mouth, one after another. Sayaka-san took it all, swallowing rhythmically without spilling a single drop. Once I was finished, she slowly pulled away, her lips acting like a vacuum to milk the last few drops before giving the tip a final, lingering kiss. My hips buckled slightly as a final shiver ran through me.
Seeing me like that, Sayaka-san gave a faint, knowing smile.
”Good morning, Master,” she said softly. I gave her a quick kiss, and then we hopped in the shower together before breakfast.
After we ate, I checked my Mana Capacity⁴ while she gathered the trash. Still D-rank. It felt like I should be due for a level-up soon, but I pushed the thought aside and finished my coffee. When the time came, I headed to the service room to gear up. Sayaka-san helped me with the buckles, making the process twice as fast.
”Oh, that’s right,” I said, remembering Rock. “Sayaka-san, remember how I told you about the Magic Sealing Crystals⁵-the items that have monsters trapped inside?”
”Yes. Like the one with the Kobold?” she asked.
”Exactly. Well, that Kobold evolved into a Kobold Defender. I’m planning on giving him my old leather armor and a short spear I picked up yesterday.”
I gestured to my old, battered set in the corner and pulled the spear out of my Magic Pouch. Kobold Defender was the official name now-it showed up that way when I used Appraisal⁶ on the crystal. It probably has some fancy demonic name, but the system translates it into something easy for us Japanese testers to understand. I’m guessing I’m the only one with a Sealing Crystal, which is why my name for him stuck.
”Evolution means he’s stronger, right?” Sayaka-san said. “That makes me so happy, knowing you’ll be safer, Master.”
”Yeah. Anyway, I want to summon him here to get him geared up before I reseal him. I didn’t want to just pop him out and scare the hell out of you.”
It was easier to do it here than to haul all the gear into the dungeon. I would’ve preferred to just keep him summoned while I walked through the safe zones and teleport rooms, but that would definitely cause a panic. Best to wait until more testers have crystals before I start walking my dog in public.
”Thank you. I’ve never seen a monster up close, so I’m a little nervous… but if it’s a Kobold, I think I’ll be okay,” she replied.
”He’s not as scary as the ones in the training videos,” I promised. I funneled some mana into the crystal and activated it.
”Wan!”
Rock appeared instantly, panting happily and looking at me with big, friendly eyes.

”Eh? He’s… he’s cute!” Sayaka-san’s eyes lit up.
Cute? I mean, he’s got some charm, but he’s still a bipedal dog-man.
”U-um… can I touch him?” she asked.
”Go ahead. Rock, sit,” I commanded.
I gave the order so it would be easier for her. Rock barked once and dropped into a perfect seiza⁷-kneeling politely on the floor.
”Kyaaa! He’s sitting like a little gentleman! So cute!” she cried.
She started scratching under his chin and rubbing his head. I still didn’t get the seiza thing, but whatever. The girl had guts, though. Even if he looked friendlier now, he was still a monster. She’d seen the footage of me fighting these things; she knew they were man-eaters. Yet here she was, rubbing his ears like he was a golden retriever. She seemed way too good at it, too.
”Did you have a dog growing up, Sayaka-san?” I asked.
”Yes! We have a Shiba Inu at home. He’s the sweetest thing! ♪”
”That explains it.” No wonder she said she’d be fine if it was a Kobold. To her, it was just a bigger dog.
”Sayaka-san, help Rock into the leather armor. Rock, drop your shield and do what she says.”
”On it! Rock-chan, be a good boy and stay still, okay?” she said.
”Wafun!”
Rock was a perfect angel, staying completely still while Sayaka-san strapped the armor and gauntlets onto him. Meanwhile, I stowed the old chest-drop shield he’d been carrying. I handed him the short spear and a heavy rucksack filled with half our emergency rations and water.
”Not bad,” I muttered, looking him over. Decked out in leather and steel, holding a spear and shield, he actually looked the part.
”You look very brave, Rock-chan!” Sayaka-san said.
”Wafun!” Rock looked practically proud of himself.
”Just needs a belt knife and he’s set. Alright, Rock, back inside.”
”Wan!”
With a flash of light, he shrank back into the crystal.
”That’s amazing… just like that,” Sayaka-san said, eyes wide.
”It’s a handy item. Here, look.” I held the Magic Sealing Crystal up so she could see the tiny, sealed image of Rock inside.
”Ah, Rock-chan!”
”He’s tucked away in there. I’ll need your help again when we upgrade his gear,” I said.
”Yes! I’ll take good care of Rock-chan!” she promised.
”He’s a soldier, not a pet,” I reminded her, though I knew it was a losing battle. “Anyway, I’m heading out. Keep an eye on the place. There’s a matcha cake in the fridge for you.”
I knew she was too polite to buy treats for herself, so I’d snuck it in there while she was doing the trash earlier.
”Ah… Master… thank you so much.” Her eyes started to well up.
”Don’t mention it.”
I gave her a wave, a final kiss at the door, and stepped out into the hall. Time to see what the dungeon had for me today.
