Despite being only ten, young Gwen Tennyson had quite the dirty mind. Although she hated having to spend her summer vacation with her doofus cousin Ben, it had some interesting results. Gwen would often catch her cousin posing in front of a mirror in various alien forms, and therefore get glimpses of these aliens' genitals. Some of them were fascinating, all with different sizes and different features.
Gwen occasionally thought about losing her virginity to one of these aliens, but the idea was usually followed by a reminder that said aliens were still Ben. That disgusted her, if she was going to lose her virginity, it would have to be with a real man.
She didn't know who that man would be, that is until she caught her grandfather doing something after the kids were supposed to be asleep. After taking one peek at Max and his giant package, that sealed the deal. All Gwen had to do now was plan on how she would convince her grandfather to have sex with her.
She decided she wouldn't convince Max, but she would use a few spells to trick him. An illusion spell, and maybe a love spell. If Max were to knock her up, Gwen wouldn't mind spending the rest of their lives together, raising their child. To anyone else, Gwen would probably sound insane, even considering having sex with her grandfather was crazy enough, but to be impregnated? He'd probably get arrested.
But Gwen didn't care. Ever since she got her first real look at a pregnant woman during a trip to the mall, she wanted that figure, and she would do almost anything to get it. Having sex with Ben was still a major no.
So Gwen waited until the following night to make her move. Ben was out cold, and a spell made sure he would stay in a deep sleep for at least eight hours, plenty of time. With another incantation, a pink cloud of dust spread around her body. To anyone else, Gwen would appear as her grandmother Verdona, albeit around her late twenties. Max would likely see this as a dream, which would work to Gwen's favor.
Gwen made her way into the main area of the Rustbucket, and rubbed Max's shoulders from behind. The older man sighed in relief, and stretched his arms over his head. "Thanks, Gw-" His eyes widened upon seeing Verdona. He began to tear up, and turned around, giving her a tight hug.
"Verdona!" Gwen smiled, running her hand through his hair. "Yes Max, it's me." Before Max had a chance to respond, Gwen put her finger to his lips. "Don't talk dear. Why don't we see if you've still got that spark?"
Max nodded, and after a minute or two of fumbling to get undressed, the two began to make love. It took about ten minutes, but eventually the deed was done, and the spell was still in full effect. That is, until Gwen moaned "Grandpa" instead of "Max". The Plumber blinked, snapping out of the spell.
"G-Gwen?!" He screamed, but in a moment of quick thinking, Gwen pulled him in for a passionate kiss, applying another, more powerful spell. She pulled away, and smiled. "Yes, grandpa?" Max was blushing a deep crimson, and shook his head before running his hand through his granddaughter's hair. "It's nothing, I'm just amazed at what a beautiful young girl you are."
It was at that moment that Gwen had claimed victory. The spell she had cast was permanent, and any bonding her and Max did would only strengthen its effects. "Imagine how beautiful I'll be with your baby in my belly." Max hesitated for a moment. "But Gwen, you're only ten, you have a long life ahead of you."
Gwen gave him another kiss, then giggled. "Grandpa, I'm basically at a college level. I can finish school whenever I want. But for now, I want to be with you." Max sighed. "Well what about Ben?" Gwen thought about it for a moment. "I could turn him into a girl. That way we could both have your children!"
Max would be lying if he said the idea didn't interest him. "Alright Gwen. But before we do that, are you ready for round two?" Gwen wrapped her arms around the neck of her new lover, and whispered, "Ready as I'll ever be, grandpa."
