Big Sister's Undies

The first time I tried on girl's underwear, it was my big sister's. While she was at her practice; I tried on one of her underskirts, white with lace at the hem. I took off my shirt and trousers, slipping the underskirt over my underpants. I started to pleasure myself; the underskirt felt soft, it was nylon. After half an hour, I stopped and felt strange, but great! I was sweating and my underpants felt damp, so I changed them. I put on a pair of my sister's panties; they were light blue with lace at the leg holes. I had lot of pleasure with my big sister's underwear; I even tried on my Mum's underskirts as well.
