Embarrassing discovery.

I stand under the hot water, mindlessly massaging my balls and my hardening cock. I know it's odd, but I've got pretty big balls, and they can be nice to rub when I masturbate. I idly realize that I left my shower gel in my bag and I momentarily entertain the idea of jumping out and running naked through the apartment to grab it. My cock gives a little excited twitch in approval, even reaching its full hardness, but my brain win out and I decide to just use Ashley’s for today.

As I search through the bottles on the shelf, trying to find the least girly products I can use, I pick up what I think is a small black bottle. I realize after I pick it up how strange the shape is, then that there's no cap on it. Although I'm not familiar with them I slowly put the pieces toegether together and realize what I'm holding.

With a jump like I've been shocked, I drop my sister's butt plug to the floor of the shower, and then quickly wash my hands with the nearest soap product I can find. Although I'm disgusted I can’t help but remember what Ash said earlier, about all the things she’s been up too. Now my mind is really racing! I look down at the toy and unwanted images of my sister I’ve never imagined invade my mind unbidden. I held something that she put in her ass! She likes things in her ass! My sister is into anal! She's a buttslut! I can’t shake the thoughts rushing through my head and I don't notice that I'm still hard despite all this.
