I (26m) accidentally flashed my friend (25f)

One night I'm at my friend's place and we are dying each other's hair. We are pretty close so we start chatting about our sex lives and we always tell each other all the dirty details. Well, while she's telling me about her and this girl she hooked up with the night before, she's drawing a design in my hair and idk what it was about her basically in my ear telling me how she fucks that got me SUPER turned on. So, when it was time to go rinse off my head I closed the bathroom door behind me bc I didn't want her to see my bulge in case she walked in.

While rinsing the bleach off my head I ended up starting to get my shorts wet, so I took them off so that I wouldn't be sitting in wet shorts the rest of the time that Im there (plus my dick needed some ROOM). After I finish rinsing, I'm staring at myself in the mirror, tryna see what needs to be touched up, when my friend walks right in. I'm butt naked at that moment (went commando) and my dick is still at half mast at this point.

She screams, I scream, my dick swings in her direction, and she takes a sec to close the door. Maybe TOO long to close the door. Now, I don't got the biggest package but I'm not tiny either, but idk what possessed her to take what felt like a good 30-60 sec look at my cock.

She closes the door and loudly apologized screaming "why are you naked???". I'm standing there, thinking about what just happened, and realize that I'm rocking a full hard-on. After a lil research later i think I may be an exhibitionist cuz that turned me the fuck onnnnnnn.

Anyway, after I managed to calm my dick down I put my shorts on and went back to her room. While it's a lil awk at first I explained to her why I was naked and thought the door was locked. She says "it's fine" and we change the subject. We spent the rest of the night like normal but I caught her glancing at my crotch a few times.

Idk what's gonna happen with her but now it's hard for me not to see her a lil different. Maybe, I'll wear tighter shorts next time I'm with her and see what she does.
