I started to dress in her bras, panties, and nighties more and more.
Especially at night I would wear them to bed.
One night my sister was mad at me and came in and yanked the sheets off of me and saw I was wearing her nightie.
She immediately called me a sissy and queer.
She told me to take the nightie off and as I did she realized I was wearing her bra and panties.
She looked at me stunned and then came up to me closer to inspect the bra.
She then said I was meant to be a sissy as the bra fit perfectly.
