How long had I been asleep...?
After having sex with Da-bin and cumming twice, I'd passed out. Not that I'd satisfied her—I'd finished way too quickly both times.
The perk currently applied to me boosted my stamina by 1.5 times. It was better than before entering this netorase loop, sure, but that multiplier still wasn't enough to cure my premature ejaculation problem. Especially compared to the 3x stamina perk from the previous round—the difference was huge. Back then, I could bring Da-bin to climax on my own. And during sex with her, the inevitable memories of netorase that flooded my mind only aroused me more, making me cum even faster.
How can I get better at sex with Da-bin...? No good ideas came to mind.
Lost in random thoughts, I woke at dawn and noticed Da-bin wasn't lying next to me on the bed where she should have been. Had she gone to the bathroom? Something told me I needed to check what she was up to. I quietly got up and peeked through the crack in the door into the living room.
!!!!!
Da-bin... was masturbating in the living room.

I watched her masturbate for a long while before slipping back into bed and pretending to sleep. We'd lived together for quite some time, but this was the first time I'd seen her like this. Was sex with me not enough for her...? It bugged me even more that she'd done this on the very night we'd had sex.
Thanks to the perk from the regression, her lust was heightened. Her body was already different from before... And I'd stimulated her desires even more by suggesting netorase. Even if she hadn't lost her feelings for me during the netorase acts, the thrill of that forbidden excitement must have raised her threshold for stimulation.
My head was a mess. I'd heard women could reach higher peaks of sexual pleasure than men. Maybe Da-bin was thirstier for it than I was right now.
She stayed in the living room for quite a while before coming back to the bedroom. She quietly slipped under the covers and went to sleep. Seeing her handle her lust alone like that... it even felt pitiful.
If she couldn't be satisfied with sex just with me... was netorase the only option I had...?
My worries spiraled through the night. Then, an idea hit me from something that bastard Park Jun-seo had done—something I hadn't considered before.

Da-bin and I finished up at the cafe like usual and headed home. The thing I'd prepared to satisfy her had arrived, but I hadn't brought it up yet. We got home, ate dinner... and then Da-bin said something she'd never mentioned before.
"Oppa... I'm gonna head to the gym."
"The gym?"
"Yeah. I wanna work out a bit..."
"Want me to come with?"
"No, it's fine, oppa. You've been tired from work."
"Mm... okay, Da-bin. I'll drive you there."
"Yup!"
Da-bin, who was always far from athletic, suddenly wanted to go to the gym. She was definitely starting to change.

.
The dull clank of metal on metal. The relentless whir of treadmills. Upbeat music played in the gym, but Da-bin felt a raw, unpolished vibe here. Was it the unfamiliar sounds...? Or the sight of men working out intensely...?
For some reason, her heart pounded faster.
She changed into workout clothes and hopped on a treadmill, starting to run. Sweat beaded all over her body, her thighs starting to ache. A pleasant fatigue settled in.
Good thing I came here... If I don't exercise, I might end up doing something weird again like last night...
It makes me feel guilty toward Do-yoon oppa when I do it alone... If I work it off with exercise, I won't crave touching myself like yesterday, right?
Da-bin ran on the treadmill for a long time, venting her pent-up stress. As she stepped off, drenched in sweat, a familiar voice rang in her ears.
"Hey! Im Dda! What brings you here?"
A voice she wasn't sure whether to be happy or annoyed to hear. It was Choi Hyun-woo, her college senior and Do-yoon's classmate.
"Hyun-woo oppa?"
"Yeah! I work out here!"
"Oh..."
"You here to exercise too?"
"Yeah. I just signed up today..."
"Whoa, Im Dda! Big decision! Trying to lose weight?"
"Huh?"
The teasing started the moment he saw her, poking at her in that playful way. Classic Choi Hyun-woo.
"Living with Do-yoon made you gain weight, huh? But it's all in your chest, so it's fine?"
"Hey! Choi Hyun-woo!"
Unable to hold back, Da-bin snapped back at him casually like old times.
"Ah—sorry, sorry! It's a compliment, Da-bin."
"Oppa, seriously! Even here? There are people around..."
"Haha! I said it's a compliment, Da-bin. Anyway, perfect timing! Want me to show you some moves?"
"No thanks! Gross!"
"You only did cardio, right?"
"Stop following me!"
"Weights are better if you do them together?"
"Argh, seriously!"
"Hey, it's hard to find someone who'll teach you properly. The gym owner’s my friend too—let me know if you need help!"
"I'm leaving!"
"Same old temper, Im Dda. Hey, since you're here, let's grab drinks with Do-yoon next time!"
"Fine!"
Da-bin hurried out of the gym like she'd seen something she shouldn't have.
Of all places, I run into Hyun-woo oppa there... Ugh, annoying...

I pulled up to the gym when Da-bin texted. She got in the car, her body soaked in sweat. Probably skipped the shower because it was her first time and felt awkward. The musky scent of her body aroused me. Good girl for not washing up. But she seemed really pissed about something.
Pouting in the passenger seat, she grumbled.
"Oppa! I ran into Hyun-woo oppa at the gym! He teased me right away—pissed me off..."
"Guess that's where he works out, huh?"
"Yeah! Argh!"
"Want me to call and warn that jerk?"
"Sigh... no, it's fine, oppa. He's always like that—I just have to deal with it..."
"Tell me if he does it again. I'll chew him out."
"It's not his first or second time... Sigh, I must be the idiot for knowing him..."
"He is pretty unique. Anyway, Da-bin, how was the workout?"
"Uh... yeah! Just running, but it felt good."
"Good. No weights?"
"Mm... not yet?"
"If you need, I can sign up too and show you proper form."
"No, oppa needs rest after work... I'll stick to running for now."
"Okay, Da-bin."
I drove us home. She headed straight to the shower, and while she was in there, I pulled out the delivered package. What I'd ordered was a rotor, similar to the one Park Jun-seo had used before.

.
Thankfully, Da-bin didn't mind me pulling out the rotor. I used it to heat her up before sex... but I still failed to bring her to climax. If anything, her body was so revved up now that she ended up in an even more frustrating state.
Should I use a dildo or something...? But that grossed me out. I worried she'd stop looking at my dick altogether if we did... But the biggest problem with our sex right now was that Da-bin's stimulation threshold had risen.
The netorase taboo thrilled not just me, but her too. She couldn't feel that with regular sex with me. The most crucial arousing element was missing.
Since we'd only had vanilla sex before, the netorase with Park Jun-seo might have imprinted on her even deeper. From the moment we involved that guy, maybe we could never go back to our normal selves...
In the end, all I could do was ask Park Jun-seo for netorase again. And to prepare for things going wrong, rack up as many points as possible this time. If netorase with him started messing up our daily life... I could just regress with the points I'd saved.
Of course, now I knew points could decrease too, so no slacking.
Sorting my thoughts, I carefully opened my mouth to Da-bin.
"Da-bin..."
"Yeah, oppa..."
"Should we call Jun-seo again...?"
