[Intocn]

A few years back I was sharing a place with a girl from my university course. During a summer break, one of her friends came to visit and stayed over for a few nights.

She was a nice petite, 5’3, brunette, rock-chick type, really slim, small ass etc...
She was staying in the livingroom, sleeping on the couch while she stayed. I definitely found her attractive.
There was a mirror in the hallway that I could see the reflection into the livingroom from my bedroom. So, after she had a shower one evening, I slightly opened my bedroom door to look into the mirror. She had left the door open enough that I could see into the livingroom.

Saw her standing there in just a towel and putting away the clothes she got out of into her bag. Then she took out her top and shorts she was going to wear to sleep.
Then she took off the towel, her back was exposed in the reflection, and I saw her petite ass. Looked flat but nicely formed.
Then she turned to the side and I got to see the rest of her. Her slim frame was barely interrupted by her breasts, they were really small, a-cup type size. And I saw her nice pink nipples, poking slightly upwards.

She had no idea that she was fully exposed to me. Had a good look at her pussy, well mostly her brown pubes since she wasn't shaven. She was single, so clearly hadn't been keeping herself tidy for a guy.
She rubbed the remaining drops of water from the shower off with the towel and started to put on her tank top and shorts. Then the light went off and she got under the blanket on the couch.

I spent the next 30 mins or so jacking off over what I had seen and slept pretty good that night.
In the morning, I bumped into her in the kitchen and saw her in the same tank top and shorts. Could see her petite erect nipples poking through.
Couldn't stop thinking about her for the next couple of weeks.

So, that's one of my "something I shouldn't have seen" experiences. Have a few more if others are interested.
