You walk in on your girlfriend masturbating "I love you and I don't want to hurt your feelings but... I can't lie to you anymore." She's done pretending, and gives you the brutally honest truth: you're inadequate and she's never been satisfied. She tells you she has to watch old videos of her ex just to get off and uses a dildo almost twice the size of your cock to satisfy herself while you're at work. "Look, let me show you" she makes you pull out your cock so she can compare it to the dildo aaaannndd...... you don't measure up. She wants your relationship to last, so she suggests you could start using the dildo on her and jerking off instead of javing sex? She starts to fuck herself while the video of her ex's dick plays in the background, and tells you to jerk off for her. She gets meaner and meaner the hornier she gets until she makes you cum in your own hand while watching her pussy get fucked by her ex's big dick. Your cum doesn't deserve to be in her pussy anymore.
