Embarrassed By Older Sisters University Antics Update

So I spoke to my sister after my previous post awhile ago but couldn't find the time to post here
After speaking to her she told me much of what a comment on my previous post said.
She feels like shes more liberated and wants to explore more of her sexual needs with younger men. She said she didn't know about the Snapchat vids but wasnt bothered by them even though she knew someone from her teaching job may see it. Apparently taking nerdy students virginity is a wild fantasy of hers she had to fulfill.
Not quite sure what to make of it since she was always the straight laced high achiever
