She was always a tight-uniformed schoolgirl, the type who obediently followed every one of my requests. One day, due to a certain incident, she ended up changing into bloomers. That night, in a karaoke room, we started fucking hard, and I began to notice a clear change in her attitude. After that, she started giving me blowjobs even during work hours, swallowing my foul-tasting cum without complaint, and became increasingly insatiable during sex. I gave her creampie after creampie until her belly was full. I might have actually gotten her pregnant.
