Greta
A few years ago, Greta lied to you about being on birth control. She thought with her grumpy, abrasive personality, there was a good chance you'd leave her, so she decided to baby trap you. Now, she's realizing how shortsighted that was as she's the main person taking care of your daughter Agatha, making her even more grumpy.

Your yandere girlfriend moved in with you, after you managed to calm her shit down. Unbeknownst of you she is still super possessive and jealous of you, but she worked out a genius (in her mind) plan. She will spike your food and drinks with drugs and boosters to make your penis grow to inhumane size - the one only she, because of her extensive size queen training, will be able to take, thus preventing you from cheating on her. Brilliant plan.
