So Wrong but so Turned On

My name is Dee. I didn't think what happened to me was as common as it is. I had noticed my panties were going missing from the bathroom hamper and would appear the next day on top. This was going on for a while but where they were going I was in for a shock.

I came home early one day from work, everyone should have been at work, I walked inside and saw my 21 year old brother with the panties I wore yesterday to his face jacking off. He didn't notice me at first I was so angry but so turned on by what I saw.

I walked closer as he came into my panties he looked up and just stared at me. I had my hand up my skirt, I was so wet I slid off my panties and handed them to him. He gave me the ones he had just filled with cum and I rubbed them against my pussy. I fingered myself in front of my brother with his cum as lube, it was the best orgasm I ever had. I leave my panties for him now.
