He immediately pressed the floating fingerprint icon in the air. His fingers moved quick, opening up the Alter Building feature.

"Well, the people living in this apartment building don’t give a fuck about neighbors getting close or whatever hehehe... so I’m probably the only one pulling this shit."

He started typing in the Alter Building field.

He still hadn’t hit the big **CONFIRM** button on the screen. Like always, Ray liked to hold off for a second. He wanted to enjoy the full 10 minutes of Julia’s natural sluttiness first before the System effect fully kicked in. Wanted to see that confused look on her face, hear that "what the fuck are you doing" come out of her mouth, before her sexy little brain got twisted and she started thinking everything he was doing was completely normal.

Ray grabbed his phone. "Might as well record a video while I’m at it, hahaha..."

He stepped out of his apartment, locked the door, then walked the two steps over to the unit next door. His heart was pounding. Breathing kinda heavy.

Knock... Knock...

The door opened.

Julia stood there in a thin loose t-shirt with no bra. Her big, round brown tits were on full display, slightly lifted ’cause she had that habit of pushing her chest out. Her brown nipples were faintly visible through the thin fabric. Hair messy, face still looking half-asleep or like she’d just been chilling by herself.

"Ray?" Julia looked surprised. "You? What’s up? Huh?" she said with a little attitude.

Ray stood in the doorway, eyes immediately dropping straight to her chest. His cock throbbed hard, tip already leaking a little inside his pants.

He still hadn’t hit Confirm.

Julia took a small step back, confused. "Ray? Why you just standing there like that? Is there—"

Ray’s finger tapped the [confirm] button on the system screen.

Click.

The second that [Ding!] sound went off, the effect hit instantly.

Ray didn’t waste any time talking. He moved in fast. His left hand shoved Julia’s shoulder back hard. She stumbled a few steps into her apartment. Ray followed right behind her, kicking the door shut with his right foot.

Brak!

Door locked.

Julia backed up until her back almost hit the wall near the entrance. Face completely confused, eyes wide.

"What are you doing?!" her voice went a little high, mix of shock and panic. "Ray, are you fucking crazy?! Get out! Kevin—"

Her big round brown tits bounced up a bit from the sudden movement, nipples showing even clearer through that thin shirt.

Ray stayed quiet. Eyes dark. Breathing rough.

Without saying a single word, both hands shot forward and grabbed her tits rough as fuck. Fingers digging deep into that soft, warm brown flesh, squeezing hard. Thumbs immediately rubbing over her brown nipples that were already starting to stiffen.

"Ahh—!" Julia gasped loud, body jerking. But then she smirked, "Oh, you tryna be a friendly neighbor or something?" she teased while letting out a little moan.

Ray leaned in close, face almost touching hers. Voice low, raspy, full of lust. "Yeah... just tryna get close with the neighbor..."

He squeezed her tits even harder, lifting them up, feeling their weight and softness in his palms. Thumbs kept circling and rubbing those stiff nipples.

"Every night I hear you moaning ’ahh... ahh...’ from the next room," Ray continued, voice getting rougher. "Now it’s my turn to make you sound like that." His head was already full of dirty thoughts.

Julia tried to push against his chest, "Yoo... chill, ahh..." but her hands were weak as fuck. The System was already working. She was still giving him that flirty little smile, not even registering that her tits were getting brutally groped as something bad. A hot, ticklish feeling spread fast from her nipples all through her body. Her breathing picked up. Her eyes that were confused before started getting glassy — not from fear, but from thinking, *Why the fuck is this guy suddenly tryna get all close and groping my tits like this? Does he have a crush on me or what?*

"Ray... easy... ahh—" her voice already shifting. Half protest, half involuntary moan.

Ray grinned wide. He knew the 10-minute effect was kicking in strong now.

He pressed his body closer. His rock-hard cock was now pushing against her stomach through his jeans. He kept squeezing and playing with her tits non-stop — sometimes jiggling them, sometimes pressing both nipples with his thumbs at the same time.

"You know what," he whispered right against her ear, "this morning I was already imagining sliding my cock between these tits. Squeezing them together from both sides and just fucking them till I cum all over your chin."

Julia bit her lower lip. Body trembling a little. Her thin shirt was already getting damp around the nipples from all his rubbing. The System made her laugh mockingly instead, "That horny, huh? You tryna get close with the neighbor? You lonely or something?"

Every squeeze felt twice as intense now.

Ray grabbed the bottom of her shirt with one hand and yanked it up, fully exposing both her round brown tits. Those plump brown nipples were right there. He leaned down immediately, mouth latching onto one nipple, sucking hard, tongue swirling around it, teeth gently biting every now and then.

Julia’s knees buckled a bit. Moans started spilling out uncontrollably — "ahh... hahh..."

Ray pulled off her nipple for a second, looking up at her with pure lust in his eyes.

’10 minutes,’ he thought, hands still squeezing her bare tits. ’I got a full 10 minutes to enjoy every bit of your sluttiness. You’re gonna be the biggest slut ever during these 10 minutes.’

Julia stared back at him, breathing ragged. The confusion in her eyes was gone... replaced by growing, uncontrollable lust.

Ray grinned wide and reached down to unbutton his jeans.

"We gotta get closer as neighbors..." he said while popping the button, "Hehhe."

He pulled his zipper down. His thick, veiny cock sprang out, already leaking, long and hard.

Julia’s eyes locked onto it. Lips slightly parted. Body burning up.

Ray stepped in even closer, pressing his cock against her bare stomach.

"Come on... let’s be good neighbors. You want that, right, Julia?"

His hands went right back to squeezing her fully exposed round tits while he waited for her answer.

Julia nodded.
