It was hot, so I was left in my underwear in the living room, lying on the floor, spreading myself wide open without realizing the window was wide open. When I lifted my head, I saw my married neighbor watching me from afar, his eyes glued to my pert ass. I pretended not to see... but slowly opened my legs, my panties already soaked. He licked his lips, adjusted his hard cock in his shorts, and I almost moaned just imagining it. Minutes later, I heard the doorbell. It was him. Nervous look, heavy breathing... but his eyes said it all. I just turned my back, leaned against the sofa, and stuck my ass out. "Close the door and come..." I whispered. He didn't think twice. He pulled my panties aside and slammed his thick cock into my winking asshole. I screamed with pleasure, my entire body opening for him. Each thrust was a shock, a forbidden delight. He held my waist, thrusting deep, until I trembled and came hard. My ass throbbed, receiving hot jets of milk, dripping down, making everything dirty. I was left panting, wet, while he hurriedly adjusted his pants, whispering in my ear: "This is just between us."
