I was furiously stroking and not being all that quiet about it. Mom opened the door to my bedroom and said, “Honey you need to be a little more disc...eet. If I can hear you, if others were here, they would hear you too.”“Look mom, you come in when I’m being quiet, so I think you like seeing me jerk my cock, in fact, I know you do.” I said.“Honey, I’m no prude, I know boys have raging hormones and that they masturbate. I’m just saying you need to be more discreet.”“BS,” I replied.“Look mom, you. All I could think was oh great, I have a hardon and she is going to stick a finger in my ass and play with my glands. She squeezed some cold liquid on my ass crack and I heard the snap of the glove. She explained what she would be doing and I agreed. She started to push and once her finger was in she started to feel around and I could feel a tingling in my balls and the tip of my cock. Then I heard her mumble, oh there it is. She started to lightly massage it and after about what seemed. Six years later I was giving hand-jobs to who-so-ever carried my books home after classes.Of course as I developed and grew, nothing was hidden from view in the home, but it was when we joined in on holidays to exotic beaches where like minded bohemian strangers were given access to my budding bulges and shape curving hips and buttocks, things started changing, men getting erections excited me.In all families, especially with open minded siblings we carry dark sexual secrets as nice baggage,. I tried to hide it but she said don't hide it I saw the outline of it when you got out of the pool. It's pretty big, I said it had to be big looking at that hairy cunt of yours. She then opened her legs and pulled the gown out of the way, that was the largest cunt I ever saw. I knew Dot was asleep and would not wake up so I stood and dropped my bottoms, and my cock stood straight, she said she had never seen a cock that big, I told her why not touch, she started jacking my cock as I fingered.
