Starting when I was very young I secretly liked watching my older sister. It started by accident when as a little kid I liked to go up and play in the attic. One day while I was up there the light went out and I saw some light coming through beside a big vent pipe going into my sister’s room. I opened it up a little and realized I could see my sister’s entire room. So I started going up there when I knew my sister was in her room, especially when she had friends there. To me at first it was a game and I pretended to be a spy listening to my big sister sharing secrets with her friends. But as I got older things changed I was looking in her room hoping to see her changing clothes and to my delight on occasion seeing her friends changing. At times seeing them totally naked, then jerking off.
I’d not only seen Sara naked, but I’d watched her masturbate and a couple of times saw her sucking her boyfriend’s cock. I’d gotten to the point where any time I jerked off I’d be thinking about my sister. She was hot at about 5-6, 110-lbs, 34-C tits and a flat tone tummy and very sexy round ass. A natural blonde with blue eyes, and really full lips I often fantasized about having wrapped around my cock. One day when I was snooping around in her room I ran across a bunch of pictures taken when she and a few of her friends had gone to the lake and she had on a bikini that was so tiny she might as well been naked and I took a couple of them as well as a picture of one of her friends in an equally revealing bikini. I started using them when I’d jerk off, which was quite often.
One day when I thought I was home alone I stripped down and was stretched out on my bed jerking off looking at one of the pictures of my sister where her tits were almost totally exposed when I heard something and looked up and saw my sister standing in my doorway watching me with her hand between her legs rubbing her pussy through her shorts. When she knew I’d seen her she started to laugh and walked over to my bed and grabbed the picture out of my hand and said she thought she was missing some pictures. She was more interested in my going through her stuff than catching me jerking off. And she wouldn’t let me get up and put clothes on. Then she looked down and commented on what a big dick I had, saying it was bigger than her boyfriends.
She sat on the side of the bed and told me to finish what I was doing. But it wasn’t easy getting hard as nervous as I was. The next thing I knew she’d pulled off her top and was sitting there topless, then said let me help and started playing with my cock. In no time I was rock hard. But instead of stopping she started to stroke it. She was jerking me off and fondling my balls, then I got the shock of my life when she leaned over and started sucking me off. With those big tits right in front of me I couldn’t resist and reached over and started groping her tits. I’d been afraid she’d stop sucking my cock but instead it looked like it turned her on and she started taking even more of my cock and sucking harder. It wasn’t long before I shot off in her mouth and she swallowed every drop of my cum. When her head came up she had a huge grin and there was just a little bit of cum on the side of her mouth she licked off.
She started telling me how important it was not to tell anyone what had happened because brothers & sisters weren’t supposed to do things like that and people would think we were sick and perverted. Then said and if I told anyone and she found out she’d never suck me off again. As she was talking I’d been continuing to fondle her tits and she asked if I liked her tits? I said I did and she told me to suck them. As I sucked her tits she was asking things like if I’d ever sucked a girls tits before or had a girl suck my cock and then if I’d ever fucked a girl? I said no to all and she said I had a lot to learn. She stood up and slid her shorts off and was standing there totally naked, then had me feel of her pussy and slide my fingers inside, I also reached around and started squeezing her ass and told her what a nice ass I thought she had. I was surprised when she asked if I’d ever thought about fucking her in the ass when I’d been jerking off? I said I had and she smiled and said maybe we could try that one day.
We got dressed and she wanted to see what pictures I’d taken from her room and when I showed them to her she asked where the rest were? I promised her those were the only ones I’d taken. She got a worried look and said if our mother had found them she’d have said something. I told her to come with me and went into our parent’s room and showed her where our dad hid his porn magazines I’d on occasion sneak out and return. We looked and on the bottom in an envelope that I knew were nude pictures of our mother when we were young and sure enough there were 4 pictures of my sister. 2 Were sexy bikini shots and 2 of her and one of her friends kissing with their hands on each other’s boobs & ass. At first she was going to take them back but then knew he’d realize we’d been looking through his private stuff. That kind of freaked her out that our dad might be jerking off looking at pictures of her.
I couldn’t believe that here I was having had my older sister sucking me off and commenting on the possibility of me fucking her in the ass. I’d lied to her about the fact I’d never had a girl suck my cock or having fucked a girl but I was glad because now my hot sister wanted to teach me all about sex. Over the next year and a half my sister to every opportunity she had to suck my cock or to have me fuck her in different positions, including fucking her in the ass. She had me fuck her tits & shoot off on them which I loved and still love doing. And I even got to have a threesome with her and one of her hot friends. That was my first time seeing 2 girls having sex. I hated it when she left town to go to another college except when I got to visit. Her roommate didn’t know Sara was bi and would have freaked out if she knew. But she had no problem fucking me. As well as a couple more of her friends there.
By then I was 6-5, 260-lbs and had a thick 9 1/2″ cock so they all thought I was their age. So my sister told them I was going to our Community College where we lived. And of course when her roommate was gone my sister would fuck me. I’ve always known incest was taboo but what can I say. There’s no arguing with a hard cock or a smoking hot sister.
