Fics like Vault of Futa Ruby Rose

Slight Fallout AU- When Ruby, along with her family members, and many other citizens of Vale retreat into a Vault they are left without a male specimen to help continue the species. Fortunately for them Ruby had a little 'accident' when she was younger after experiment with radioactive energy when building a robot. She grew a dick and to this day had been an uncomfortable secret she and her family kept until the Vault's water supply, which had been laced with fertility supplements, causes all the attendants to go crazy with lust. For Ruby it kickstarted her dormant need for lust as it made her crazy for breeding all the other women. Overseer Ozma might just allow her to do just that.
