Steamy cheating sex story of a man who secretly fucks his beautiful big-breasted neighbor while her boyfriend is in the next room. Intense, risky, and passionate forbidden encounter.

Her name was Airi, and she lived in the apartment right across the hall. She had an incredible body — especially her massive, soft breasts that strained against every top she wore. She had a boyfriend, but that didn’t stop the intense sexual tension between us.

One night, her boyfriend came home drunk and passed out early. Airi texted me: “He’s sleeping… I can’t stop thinking about you.”

I quietly entered her apartment. She was waiting for me in the living room wearing a tight orange top that barely contained her huge tits. The moment the door closed, she pressed her body against mine and kissed me desperately.

We didn’t even make it to the bedroom.

I pulled her top down, freeing her massive breasts, and sucked on her swollen nipples while fingering her already soaking wet pussy. Airi had to bite her lip to stop herself from moaning too loudly.

“Be quiet… he’s right in the next room,” she whispered, even as she stroked my hard cock.

I bent her over the couch, pulled her panties aside, and thrust deep inside her. Airi’s huge breasts swung heavily as I fucked her from behind. The risk of her boyfriend waking up made everything even hotter. She kept whispering “Harder… but quietly…” while her body betrayed her, shaking with pleasure.

I turned her around, lifted one of her legs, and fucked her deep while sucking on her bouncing tits. Airi came hard, her pussy clenching around me as she covered her mouth to muffle her moans.

Finally, I pushed her onto her knees and exploded all over her beautiful big breasts, covering them in thick cum.

Airi looked up at me with satisfied eyes, cum dripping down her chest, and whispered:

“Next time… I want you to fuck me in our bed while he’s sleeping.”
