6 Gwen side 2: Fat Ass by becquerl

Gwen exhaled heavily as she leaned on the sink in the cramped bathroom of the Rust Bucket. All that ice cream from her d-date was sitting like an absolute rock in her stomach and she was really feeling it now. Really, why had she gone along with Ben when he got the largest, thickest milkshake that ice cream parlor had?

Well, that wasn't really a question. Gwen was a complete sucker for that look of boyish excitement on her stupid, loveable cousin's face. The worst part about the whole shake was that she wound up eating the majority of it since Ben kept on feeding her using his spoon. How was she supposed to turn down all those free indirect kisses, huh? Geez.

Although... Gwen stood up straight and looked over herself in the mirror. She gently reached back and squeezed one of her plump buttcheeks.

Yeah, definitely bigger than before this whole road trip started. She smirked as she squeezed it. This wasn't the first time she'd had a big growth spurt like that, but she was usually active enough that she was able to burn off the calories before they settled on her butt like this.

Gwen's smirk faded into a bashful smile as she thought back to the times in their younger years when Ben had defended her from the bullies in their classes; gallantly fending off the jeers making fun of her oversized bottom and comforting her when she cried about it afterwards. He even joined her martial arts classes with her, just so he could keep an eye out for her. She let go of her butt and covered her burning blush at the thought.

After swooning for a bit, Gwen shook her head and lightly slapped her cheeks to refocus. She turned to the side and looked at her butt's larger profile in the mirror again. Maybe... Maybe she could let it slide this time. Boys liked big butts these days, right? And all that fattening milkshake was probably going to hit her rump like a freight train overnight...

Gwen looked herself in the eye and nodded determinedly. Having to get some new panties was worth it if Ben had more to look at. Yeah, her new, not so secret weapon was gonna work out great!
