Panty stealing step brother is a masturbation addict.  |  (Random)

I know my little step-brother has issues, most nineteen year old guys do. He always seems to have one hand in his pocket doing something with his rocket if you know what I mean. I'm talking to my girlfriend on the phone, go into my bedroom to grab a sweater and what do I find but my little step-brother laying on my bed with a very guilty look on his face. I ended my phone call quickly to deal with the reason my step-brother thought it was ok to be in my room, on my bed. His pants appeared to be barely fastened and the lid was off my clothes hamper. I deducted pretty quickly he had been rifling through my dirty clothes. Even with my own reasoning I gave him a chance to explain, which he offered none. I wondered what item of my clothing he had in his possession so undid his pants to find out what he had stuffed down there besides his semi hard cock. Oh great, my satin purple panties. There wasn't any reason to get too upset with him. At his age his hormones probably are driving him crazy enough already. It kind of turned me on to think he was getting aroused at the scent of my cunt on my panties. Why not go ahead and give him something more to fantasize about? I told him it is ok to have a panty fetish. It's ok to sniff my panties just so long as he returns them to my hamper when he is finished. To let him know I had no hard feelings I told him to lay back while I let him sniff my panties while I jack off his cock. This was going to be fun, especially when I saw how big his dick is. Nothing like a good size hard cock in a girl's grip even if it was my step-brother's cock. As I stroked him with my spit for slippery lube, I asked if his cum in my panties is the reason they have seemed a little more stiff than when I originally put them in to launder. He has been stealing my panties and shooting his semen in them then sneaking back into my room to put them in my dirty clothes like they never left.

Its kind of creepy yet a turn on to know he thinks of me while he is stroking himself. My step-brother is turned on by his big step-sister, how sweet is that? I own his cock now. He will give me his cum or I will let everyone know what a perverted panty thief he is. I'm such an understanding big step-sister I let him frost my purple panties and then keep them for masturbating material later. I understand all men have needs, even little nineteen year old young men. Now that I've seen what a big dick he has I may just have to sample that inside my pussy next time my panties go missing.
