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

 

this topic comes up from time to time and people usually lamblast the person asking like they are some sort of freak. Good to see some level headed and honest people. I had mutual jerk off sessions with some of my cousins. But I had two sisters and they were pretty gals. I was older and so was out of the house as they matured.

But I have to admit that my thoughts from time to time will gravitate to what it would be like to have sex with my one sister that is still alive. Shes still pretty hot even in her late 50's (I am in my early 60's).

would never act on it, but the thought hits me from time to time.

 

Not my own family, but when they were young, I know my wife and her brother got up to some shenanigans. I use it for masturbation and sometimes we also use
it together when we make love.

 

One of my sisters was two years older than me and had a nice set of tits. I was fourteen when I came home one Saturday afternoon and looked out the window and she was tanning naked on the lawn, those perky tits pointing straight up, her red pubic patch looked so inviting and my cock got so hard I had to take it out of my jeans. I had my hand on it anyway so I stroked it a couple of times but couldn't stop staring at her and kept on.
She reached down and scratched her pubes and that got me really excited and I blew my load on the floor. I watched her for a while more until she rolled over and I got hard again at the sight of her ass and was jerking again when I heard a tractor coming into the yard. Sister got up and headed for the house with those sweet tits out and I had more cum to clean up.
I still occasionally jerk to that memory. I see her about four times a year now, she's still in great shape and I still want to look at her chest and wonder what they look like now.
And now I'm hard again and gotta go.

 

Had some about grandparents or least grams with a stand in Grandpa

 

Absolutely. If you are a woman I know within a certain age of my own at any given time in my life, there is a 90% chance I have thought about you while masturbating. But I only thought about my sister as a teenager and only a handful of times, if that. She's not particularly attractive. It's just that when you're 14-15, if you've seen someone naked, there's no way you're not going to masturbate to them because at that age, if you're not gay, you've seen like one or two people's genitals from the sex you're attracted to. Three or four if you're lucky.

I am not proud of it but I did masturbate in her presence a few times. Not to her and not in a way where I was just whipping out my penis and going at it in full view. It'd be while we were both in the living room watching TV, or whatever, and I'd do it lightly and -- what assumed was discreetly -- in an arm chair facing away from her or with the back of the couch as coverage. Only because in those first few years of masturbating, I was doing it anywhere anytime the need struck me. But she definitely knew what I was doing.

She saw my penis ALL the fucking time just because we were fairly open about nudity in my family. And there were the usual games of "show me mine and I'll show you yours" with friends and neighbors. So, I have wondered if she ever thought about my body to get off just because -- again -- at a certain age, you only have so many real life experiences with private parts to help you climax.
