Penny Crygor turned 18 and was now allowed to commit public nudity. Her first instance of being naked in public led to an encounter with a tall African American woman that befriended her. Their growing friendship/eventual interracial lesbian relationship encouraged Penny to embrace exhibitionism and also develop a specific sexual fetish: being submissive for tall black lesbians. Also on AO3.

Having supposedly given up nudism, 5-Volt went back to being a dutiful housewife. However, in the back of her mind was a longing to become naked and free once again, which grew overtime until it became unbearable. She wanted to be naked and naughty once again, but after that citation, she couldn't just go out and expose herself lest she actually be arrested for it...could she? Also on AO3.

Penny and Dr. Crygor share a strong bond as grandfather and granddaughter, but that doesn't mean it can't be strained. One shots test the limits of their love for each other. Science, holidays and drama galore, the last few chapters make for some pretty heart-wrenching lore. It's mostly just mundane family drama with familiar plots, but near the end, things get pretty dark.

Dr. Mario tells Dr. Crygor that Penny needs a shot, but she's too scared of shots. When Crygor angrily yells at Penny and scolds her for being scared of shots, she becomes heartbroken and cries. Was Dr. Crygor too harsh? (I did this since Penny is listed as a Mario character, I figured I'd be the one to have the first Mario story with her listed.)

When she is all alone, 5-Volt decides to have a little fun by taking off all of her clothes and being completely naked. She did a lot of risky things in the nude. 5-Volt was soon joined by her husband, and they walked around naked in public, had sex in public, etc. Also on AO3.
