Back when Mylie was a trackstar as a sophomore she goes into the sauna after track practice. She set the record in the 400 meter after she ran it in 55 seconds. She's tired and thinks the sauna is private, she goes in in her bra and thong, however it's not private and fat old men enter. She stays facing away from them, they stare at her buttcheeks. Her glutes very visible.

*the fat old men enter the sauna. Mylie thinks Oh no,I thought this was private! *Her buttcheeks prominent and visible
