True humiliation

[flyingmonk]

It sounds cliche, but it really happened to me. I don't remember my age, but sometime shortly after puberty. I was horny and went into the bathroom to take care of business. I was sitting on the toilet with my pants around my ankles going to town when my sister opened the door. I know she had to see what I was doing even though i moved quickly to hide it. I never forgot to lock the door after that.

Is your sister younger or older than you? Let’s hope she got a good look.

I have two sisters. The one who opened the door was the one that is two years younger than me. No way she could not have seen it

Of course, this begs the question of what your sister was doing in the school's Boys Room?

My sister (along with my classmate Susan Weinglass & her younger sister Bethany once caught me pants/underpants down in my bedroom jacking-off at age 16. The only fortunate part about it is that I had not yet reached completion. They didn't actually see my penis (I don't think) since I was face down on the bed fucking my childhood teddy bear. Poor bear! It was then that I really regretted my Dad's rule about 'no locks on you kids' bedroom doors.

For some merciful reason my Mom never questioned why Mr. Panda Bear developed some obvious stains as my teenage years progressed. One time I attempted to rinse them out with bleach but that only made the stains more pronounced.
