So, this happened this past weekend. My uncle was doing a little end-of-summer BBQ, so me, my older sis, and mom came over for food. He also has a backyard pool, so a few of us went for a swim.

After I got out of the pool, I went for a quick shower (I hate smelling like chlorine), and left the bathroom door ajar because I'm that kind of person, and also it wasn't that uncommon for our parents to do that growing up, since we only had one bathroom. Of course, just as I'm about to finish up, my sister walks in to pick up her phone (which I assume she left while she was changing into her bathing suit), and gets an eyeful of me naked. It's one of those bathrooms that has un-frosted solid glass door for the shower, so she saw everything. Now, I also have a *huge* exhibitionism kink, and I also have a massive crush on my sister, so the inevitable happened. In the time it took for her to rummage through her clothes and grab her phone I sprung a massive erection, which she saw head-on. She made some quip about "have fun" before she left and closed the door behind me. God, that was hot. I just rubbed out a quick load before I got out of the shower and joined everyone for lunch.

I assume the "have fun" comment was about my arousal, since...otherwise that doesn't make much sense. God, there's something about sharing your sexuality and body with family that's just so hot. This isn't the first time something like this has happened; when I lived at home my mom caught me jerking off a few times, and she just left a box of tissues in my room.

Knowing that my mom and sister have seen me aroused is just so incredibly hot, it just feels so natural and right to not be ashamed, and not hide your sexuality around family. Mom made sure we grew up in a very sex-positive household, so I saw and heard plenty of things, and now I'm just so turned on by it. Anyone else know what I mean?
