The week was hell. An endless cycle of part-time shifts and mind-numbing university lectures left Makoto feeling totally drained. Every muscle ached with a deep exhaustion that sleep couldn't fix, and his brain felt like sludge.
But hey, at least his savings account looked a little healthier. He'd earned a reward, a special one.
That's what led him here, to a shady little side street he normally avoided. He stood in front of a door with a cheap neon sign promising "Ultimate Relaxation."
It was one of those places. Not exactly illegal, but it had a gray-area vibe that was equal parts scary and exciting for a guy like him.
After a quick, business-like chat with the receptionist, he was shown to a small private room. The air was heavy with lavender oil and something sickly sweet that just made his heart pound faster.
Now, he was sprawled out on the massage table, a warm towel draped over him. The soft terrycloth sent a little shiver of excitement through him.
He was a jittery mess of nerves and hope. "Please let her be cute and have big boobs," he prayed to whatever god was in charge of this stuff.
Just as his mind started conjuring up images, a girl's voice floated through the door.
"I'm Yurika," she purred, the sound a playful tease. "Are you ready for our massage, sir~?"
"Yurika. Cute name," Makoto thought, a grin spreading on his face. "This is going to be worth every yen."
The door slid open. The masseuse walked in. Makoto's brain short-circuited.
It was… her!
Her own stormy gray eyes, ones he knew all too well, went wide. The practiced, sexy smile she wore twitched, then morphed into a wicked, shit-eating grin.
She was cute, alright. And the way her chest bounced when she moved definitely checked a box. But she was also his little stepsister.
"What the hell are you doing here, big bro?" she chuckled, enjoying this way, way too much.
An internal scream echoed in his skull. "What the fuck are you doing here, Yuna?!" Down below, his body decided to react to the sheer insanity of the moment with a powerful, inconvenient throb.
This wasn't happening. Of all the places in the whole city, he had to pick this one.
Yuna. His stepsister. She wasn't blood-related, a fact his stupid body was reminding him of right now. His dad married her mom five years ago, and ever since, she'd been a bratty, chaotic, and yeah, cute, pain in his ass. But this? This was a whole new level of disaster.
Her uniform was basically lingerie. The flimsy two-piece thing she wore did nothing to hide the curves she'd developed way too fast over the last few years. Curves he'd been trying his damnedest to ignore.
He must have looked like he'd seen a ghost, because she actually flinched. Her cheeks went bright red, and she instinctively covered her chest with her hands.
"O-oh my~ Big bro?!"
Her shock lasted all of two seconds before that wicked little grin returned. She giggled, a nervous but playful sound. "I work here, you know? Gotta save up for my gacha pulls."
She winked, then leaned over him with a slinkiness that was just wrong for her age. Her breasts, soft and oiled, pressed against his bare back.
A jolt of electricity shot through him.
"Didn't expect to see you here... looking for some fun?"
His brain was a scrambled mess of horror, confusion, and a very annoying, very primal arousal. "This is a normal urge for a healthy man", he told himself, but it sounded pathetic even in his own head.
He gave a jerky shrug and twisted his neck to look at her. "Wait, you work here? For how long? And what exactly do you do? Is it just… massaging, or…?"
The question just hung there.
Yuna giggled again. Her fingers started tracing little circles on his shoulders as she leaned in close. Her warm, lavender-scented breath tickled his ear.
"Only two months. And I do whatever the customer wants."
She pulled back a little, her eyes sparkling. "But with family? Strictly massage only!"
Then, her oiled hand moved to adjust the towel covering his lower body. Her knuckles brushed, not so accidentally, right along the length of his hardening cock.
He froze solid.
"Unless," she purred, biting her lower lip as her voice dropped to a whisper, "you want something extra? I really need those pulls for the new Nikke banner..."
"Nope, nope, no extra stuff," Makoto sputtered, swatting her hand away. He flipped onto his stomach, trying to crush the evidence of his body's betrayal against the table.
"Just do your damn job then," he grunted, but it came out weak. He could feel goosebumps pop up on his skin as she whispered again.
He tried to sound firm, to get things back to normal, but his damn curiosity won. "So, how far do your customers usually go with the... happy ending stuff?" he mumbled, hating himself.
Yuna let out a sweet laugh. Her hands slid from his back down to his ass, giving both cheeks a firm squeeze. "Oh, you'd be surprised," she purred, her breath hot on his ear again. "Just yesterday this old guy begged me to suck his cock."
Makoto's whole body went rigid. A hot, ugly feeling coiled in his gut.
She felt him tense up and giggled. "Don't worry, I didn't! Handjobs only, big bro. I'm not that desperate for gacha funds… yet. And sometimes I refuse to do it if the guy is too... disgusting."
Her fingers trailed down from his ass, getting dangerously close to his inner thighs. "Unless you change your mind?"
"Handjob only, huh?" he muttered. A weird, sick sense of relief washed over him. "Well, at least there's less chance for STDs…" He cringed.
"Not that I care or anything," he added quickly, the lie feeling stupid on his tongue. He had to change the subject.
"Massage harder, you're slacking! I'll tell the manager," he grumbled, trying to sound intimidating.
"Tch, fine!" Yuna huffed, but it was all an act. She put her weight into it, her small hands digging into his tight muscles. Her chest squished against his back as she put on a show of panting softly. "But you're such a buzzkill, big bro~"
Then everything changed. She ground her hips into his ass and let out a loud, fake moan right next to his ear. The teasing was gone, replaced by something sharp.
"If you tell the manager," she whispered, her voice low and dangerous, "I'll tell mom how you used to peek at my panties when we were kids."
His blood ran cold.
She slowly ground against him through her shorts, a slow, torturous friction. "And that was before I even had a proper bush~"
"As if your current bush is a proper one!" The words just flew out. A fatal mistake.
He bit his lip, hard. "Not that I peek, I just… I accidentally saw it." He shoved his face into the massage table, his cheeks on fire while his cock throbbed harder than ever. "Shit. I just admitted it."
"Liar!" Yuna squealed, bouncing on his back like she'd just won the lottery. "You totally peeked! And you loooved it~"
She slid her body down, her shorts riding up as she ground her smooth, waxed pubic mound against his hard-on through the towel.
The heat was driving him crazy. "See? No bush at all~" she teased, whispering in his ear. "Want me to show you?"
Before he could even think, her fingers hooked into her waistband. She pulled it down just enough for him to see the top of her completely bare, glistening slit. The image burned itself into his brain.
"I'll show you mine," she breathed, her voice a desperate, seductive hiss, "if you promise to buy me enough Primogem for my new Genshin banner."
