The apartment was quiet, the only light coming from the faint glow of the city outside the half-closed curtains. Sein’s room was dim, almost dark, but their eyes had already adjusted enough to see each other in soft, shadowy outlines.

Andrey was on top of her, his weight pressing her down into the mattress. His breathing was heavy and ragged, warm against her neck. Sein lay beneath him, her orange hair spread messily across the pillow. Her heart hammered wildly in her chest.

’He’s looking at me... so intensely...’ she thought, cheeks burning in the darkness.

Her gaze flicked briefly around the room she had slowly started calling home. The same plain walls, the scattered clothes on the floor, the half-empty water bottle on the nightstand — messy and monotonous, just like always. Yet this place had become hers.

They initially only intended to take the goods, but now the situation has become unpredictable. Sein, already exhausted from the battle, could only resign herself as Andrey pushed her.

Andrey finally spoke, his voice low and hoarse.

"...Sorry. I pushed you again."

Sein stared up at him, her green eyes reflecting the faint light. She tried to keep her voice steady.

"Accidents can’t happen twice in the same place, idiot."

Andrey shook his head slightly, his cracked glasses long discarded somewhere on the floor.

"No... I really didn’t mean to. It wasn’t on purpose."

Sein could only look at him. She felt the full weight of his body — heavy, masculine, and unyielding — locking her in place. No matter how much she shifted, she couldn’t move. The realization sent a sharp thrill through her, her pulse thundering in her ears.

Then, a cheerful, mischievous voice suddenly rang in both their heads.

System: Heyyy~ You two are in such a hurry! I haven’t even decided what kind of reward this should be yet, you know~

The playful tone instantly shattered the heavy atmosphere.

Sein’s eyes widened in fury. Her face flushed deep red — this time not from embarrassment, but pure irritation.

"Die, you damn System! Go to hell!"

Andrey couldn’t help but let out a tired sigh, his forehead dropping lightly against her shoulder.

Sein glared at the invisible ceiling as if she could punch the System itself.

"I swear I’m going to find a way to delete you one day..."

System: Ehehe~ So mean, Sein-chan! But your Affection Points are rising nicely because of this~ Keep going

Sein groaned and covered her face with both hands, muttering curses under her breath.

System: Alright~ Since you two are already so eager, I’ll grant this reward right away! This time’s special reward is full breast stimulation on Sein until she reaches climax. Progress will start at 0% and go all the way to 100%. Enjoy ❤

A soft ping echoed in their minds, and suddenly a translucent pink barrier bloomed around the bed. It shimmered gently, completely sealing the room in a dome of privacy while still letting them see each other clearly in the dim light.

Sein’s eyes widened as the warm, tingling sensation immediately bloomed across her chest. Her breath hitched.

"Still... better to have a barrier..." she muttered, cheeks burning. "The walls here are pretty thin..."

Andrey, still hovering over her, let out a low hum despite his own heavy breathing.

"Do you often get complaints about being noisy?"

Sein turned her face away, embarrassed, but the stimulation from Andrey was already making her body react. Her voice came out slightly shaky.

"Of course I do... and it pisses me off. I pay a lot for this place, you know."

Andrey shifted his weight a little, looking down at her with a mix of self-restraint and quiet gentleness. His hand slowly moved to her chest.

"That means you chose a bad spot then," he said calmly, his voice low. "If the walls are this thin and the rent is high, the landlord clearly overcharged you. The location is okay, but the building quality is mediocre at best. Soundproofing is almost nonexistent, and the layout makes every noise travel easily between units. You’re basically paying premium for a cheap build."

Sein bit her lip as the tingling turned into a deep, warm throb. She tried to focus on his words while her body grew hotter under his touch.

"So... that means I was scammed by that damn agent..."

Andrey nodded, his fingers moving with deliberate care as he continued to explore Sein’s body.

"Pretty much. Next time, let me check the place before you sign anything. I can spot those kinds of traps easily."

Sein let out a soft, involuntary moan as the stimulation intensified, her back arching slightly beneath him. The pink barrier glowed a little brighter, as if feeding on their growing heat.

"Shut up... and just... focus on what you’re doing right now..." she whispered, voice half-annoyed, half-breathless, her green eyes locking onto his again.

Andrey leaned down closer, his breath brushing her ear.

"As you wish."

Andrey’s hands moved to the hem of Sein’s torn shirt. Slowly, deliberately, he pulled it upward. Sein lifted her arms without resistance, but her face burned with embarrassment as the fabric slid off her body.

’He’s... getting more and more skilled at undressing me...’ she thought, biting her lip hard. The realization made her even more flustered.

In the dim light, Andrey’s gaze dropped to her chest. She was wearing a simple black sports bra that hugged her breasts tightly. Her chest rose and fell quickly with each heavy breath, the soft mounds already straining against the fabric, nipples visibly hardened beneath it.

Andrey’s voice came out low and husky.

"...Can I touch them?"

Sein’s green eyes narrowed in frustration and desire. She grabbed his wrist and pulled his hand firmly onto her chest.

"Don’t keep asking... Just do it already, idiot..."

The moment Andrey’s palm made full contact, Sein’s body jolted. A sharp, needy moan escaped her lips.

"Ahhn...!"

His fingers kneaded her soft flesh through the sports bra, slow but confident, thumbs brushing over her stiff peaks. The way Andrey looked at her made everything more intense, turning simple touches into electric waves of pleasure that shot straight down her spine.

Sein’s back arched off the bed, pressing her chest harder into his hand. Another moan slipped out, louder this time.

"Ahh... haa...!"

Andrey leaned down, his breath hot against her neck as he continued massaging her breasts, occasionally pinching her nipples gently through the fabric. The pink barrier around them pulsed softly, glowing brighter with every sound she made.

Sein’s hands clutched at his shoulders, nails digging in as pleasure rapidly built inside her.

"More... ngh... nhaan..." she whispered breathlessly, her usual tone completely melted away.

Andrey’s hands continued working on Sein’s breasts, his mind clouded with heat.

’They’re so soft...’ he thought, ’and the size is perfect in my hands. I can squeeze them fully without any space left...’

Sein squirmed beneath him, her moans growing louder and more desperate with every knead.

"Nhh...! Don’t squeeze them too hard... or I’ll hit you... ahhn...!"

Andrey nodded quickly, loosening his grip just enough while still massaging her firmly, thumbs circling her hardened peaks through the fabric. He watched her face intently — the way her green eyes fluttered, lips parted, cheeks flushed deep red.

Sein’s breathing became ragged. "Haa... haa... idiot... you’re too good at this..."

Without warning, Andrey slid his hands to her back, unhooked the black sports bra in one smooth motion, and pulled it off completely. Sein’s full breasts spilled free into the dim light — round, soft, and perfectly shaped. Her pink nipples stood stiff and erect, begging for attention.

Sein instinctively tried to cover herself with her arms, but Andrey gently caught her wrists and pinned them beside her head.

"Don’t hide..." he whispered, voice thick with desire.

Sein turned her face away, mortified, yet her body trembled with anticipation. Her nipples visibly throbbed under his gaze, the sheer tension between them making every inch of her skin hypersensitive.

Andrey stared for a moment, mesmerized, before lowering his head. His hot breath brushed over one sensitive peak.

Sein bit her lip hard, her voice barely a whisper.

"...Don’t just stare... touch me already..."

Andrey’s right hand cupped her left breast, squeezing it gently as his thumb brushed across the stiff pink nipple. Sein’s body jerked at the direct contact.

"Ah...!"

Then his mouth descended.

He took her right nipple between his lips, sucking it softly at first, letting his tongue swirl around the hardened peak. The taste of her skin — slightly salty from sweat, warm, addictive — made him groan against her flesh. He sucked harder, pulling the sensitive bud deeper into his mouth while his hand continued kneading the other breast, rolling the nipple between his fingers.

Sein’s back arched sharply off the bed. A loud, broken moan tore from her throat.

"Nngh...! Ahhn— Andrey...!"

Her hands flew to his hair, fingers gripping tightly, not sure whether to push him away or pull him closer. Every suck sent sharp jolts of pleasure straight down to her core. Her body was so sensitive now that each lick, each gentle bite, each wet pull on her nipple felt ten times more intense.

Andrey switched sides, releasing the right nipple with a soft pop before latching onto the left one. He sucked greedily now, hollowing his cheeks, tongue flicking rapidly over the swollen tip while his hand pinched and rolled the neglected nipple.

Sein’s moans grew louder, more desperate. Her thighs pressed together instinctively, hips twitching as wetness began to soak through her panties.

"Haa... haa... idiot... you’re sucking too hard... ahhhn—!"

But even as she complained, her fingers tightened in his hair, holding his head firmly against her chest. Her green eyes were half-lidded, glazed with pleasure, cheeks burning crimson in the dim light.

Andrey hummed against her skin, the vibration sending another shiver through her body. He alternated between sucking, licking, and lightly grazing her nipples with his teeth, slow then fast, gentle then hungry, never giving her a moment to recover.

The pink barrier around them pulsed brighter, feeding on the rising heat and Affection Points.

Sein’s breathing was completely ragged now, her voice turning into needy whimpers.

"More... ngh... don’t stop... ahhn—!"
