[My Devilish Girlfriend's Intimate Ejaculation Control!] My girlfriend is incredibly cute, but she's also extremely possessive. One day, while she was at work, I secretly masturbated—only for her to come back to retrieve something she'd forgotten and catch me in the act. "Your sperm belongs only to me! You should only get excited for me!" she declared, and from that day on, she began strictly forbidding me from ejaculating. Every day, she watches me struggle at the brink of my limits, smiling sweetly as she says, "Your expression is so turned on right now," yet still refusing to let me cum. Her intense domination continues to this day.
