Chris looked at this girl. His best friend Carl turned into a childhood girlfriend that he didn't quite know the name of. What would his parents name him? Carly? It's possible they'd just name her something different entirely... Chris took another sip of his old fashioned and then took another glance at this girl. He didn't stare too much at her chest, but it didn't seem like she had a lot of it... She wasn't wearing particularly tight clothing though so maybe they weren't too small. What if they were?...

Chris took a look at the TV where the crowds during a football game had a bunch of massive breasts easily visible in the background.
"Well?" This female Carl asked demanding the answer to a question that in this semi-reality adjusting that Chris did not hear. "What do you think?" She clarified to a question that Chris technically heard, but Chris didn't hear. Kinda drunk and not in his right mind Chris did what made sense to him and...
