fantasy about your brother/sister

When I was ten my brother was 17 He was beautiful, Blond haired and blue eyed and every tan muscle lay perfect in its place. He thought I was asleep one night and I watched him in the light from the street lamp outside. He lay on his back in the bed and used both hands to jack himself off he seemed huge to me at the time. But even so I watched and at some point he saw that I was watching. It turned him on more to know that I was watching and I was riveted watching him all the way until he arched his back in spasms and shot hot streams all over his belly. I think about it a lot even still.

 

I feel thats OP's sister flirting with him

 

Both my sisters are older than I am by 5 and 7 years. When I was 12 I got up early one morning to pee. I quietly walked to the bathroom as to not awaken anyone else. As I was walking by my sisters' room I noticed that the door was ajar. I quietly eased the door open a bit further and there before my shocked, adolescent eyes was my oldest sister completely naked, spread eagle and still asleep. My eyes initially focused on her pert breasts and erect nipples. I stared at them for what seemed like forever as I felt my excitement, awe and penis growing. As I scanned her naked, maturing body further my attention was quickly drawn to the wonderful patch of hair above her crotch ( I had just started to develop a descent 5 o'clock shadow "down there") and subsequently to her exposed pussy. I almost had an orgasm right there without touching myself. Sensing that I was getting too excited and might get caught I rushed to the bathroom and immediately masturbated to a furious orgasm. I had many enjoyable masturbation sessions and orgasm to that memory for years to come.

 

Good thing she didn't catch you staring at her while she was naked. Just curious, but was that the only time you eve saw her naked? Or did you find yourself trying to peek in on her after that? She must have been a really hot girl if you masturbated to thoughts of her.

 

Yes, that was the only time I saw her naked. I don't know what she would have done if she would have caught me staring in amazement, but I did still try and get a glimpse ever chance I got.

Both of my older sisters were really hot and still are to this day. It was very difficult for an adolescent boy full of raging hormones to grow up in a house with two older sisters.

 

i've masturbated to some pretty average girls that i haven't even seen naked.

 

Brother and I used to jerk off together and jerk each other off

 

Never.

 

I grew up with two gorgeous, older sisters. So yes, I fantasized about them all the time. Yes, I peeked at them naked when I could. Also, the oldest one saw me completely naked with an erection. She caught me lying on my bed, completely naked stroking my cock. That made for some interesting future masturbation fantasies!!!

 

I admit, that is amazing way for the two of you to bond.

You may or may not have had a lot in common, but, you had THOSE moments.

I envy you.

 

Once.
I pictured my brother bent over while I shoved it in his ass and reaches around to play with his hard on. After I came, I felt ... off. I didn't like the experience. Now I never fantasize about family. Ever.

 

That's good
