My sister's panties when I was around 4 or 5. Three of my sisters (ages 6, 8, 11) used to dress me up like I was a living doll for them, dress, panties, makeup, wig and shoes. Then they would parade me around and show everyone in the house and the nabors too. My other sisters (ages 20 & 22) didn't show much interest. Later (I know I was 5 at this time) I put on a pair of my mothers stockings.
