First time with my sister.

My sister caught me jerking off and it worked out great.

I'd started spying on my older sister at a young age at first as a game and then because she was hot and I took every opportunity I could to see her naked and luckily got to see a couple of her friends nude as well. I'd seen all her secret hiding places and one day while snooping found some Polaroids she had hidden of her in a bikini, only her tits were hanging out of the top. There were several like that so I took a couple of them and started to use them for fuel when I'd jerk off. I'd fantasize about all the things I'd like to do to her, mostly sucking her big tits, fucking her, and my favorite having her suck my dick. Of course I didn't think there was a chance in hell any of those things would ever happen, so I was happy jerking off to my pictures of her big tits. Then one day I got the surprise of my life as I was laid back on my bed naked stroking my cock thinking I was home alone and there was my then 16 yo sister standing there with a big grin on her face. I think at first she thought it was funny catching her 14 yo brother jerking off, then a bit exciting when she realized I had quite a big dick for my age as she surprised said my cock was bigger than her 20 yo boyfriends or any guy she'd been with. Then it turned to anger as I tried to throw the picture in my hand under the bed, but instead it landed face up right at her feet.

She wasn't bothered that I was jerking off thinking about doing what ever to her. But she knew I had to have been snooping through her room to have found the picture. She called me a little pervert, but less than 5 min later had taken off her top and was letting me fondle her tits and then suck on them as she played with my balls. And only a few minutes later she was sucking me off. Admittedly it wasn't my 1st blowjob as one of my buddies had sucked me off a couple of years before and had done so several times since. Though I never returned the favor but if he wanted to blow me fine. But I realized I hadn't had a good blowjob until my sister sucked my dick that day. I'll admit I didn't last long and filled her mouth with cum. But she had me suck her tits and run my hands over her sexy body some more and had me rock hard again in no time. She sucked me off again, this time taking her time going down licking & sucking my balls & working her tongue up and down my shaft and around the head. As well as having me straddle her and put my cock between her tits and she pressed them together having me fuck her tits, admitting she'd accidentally seen our parents do that and it had turned her on. Finally she finished sucking me off taking my second load of cum down her throat, but promising next time to be prepared and have me shoot off on her tits. Then gave me a sexy smile and said or in her pussy.

She was true to her word as only a few days later we were home alone and knew we would be for hours. She came in my room naked and had me lick every inch of her body including inside her pussy for several minutes and rimming her ass. But it was fair because she licked my asshole a little later sticking her tongue in about an inch and a half. She sucked me off a little and then sat back on her legs cupping her tits and had me stand by the bed and jerk off until I shot my cum on her tits. She rubbed my cum on her tits like it was some kind of skin cream. It turned out a boy had told her that a guys cum made her tits soft and made them grow bigger. Though that had been several years earlier, but at 34'C they were nice. She sucked me off several more times over the next few weeks and let me fuck her tits until I shot off. She also let me put my cock in both her pussy and her ass but only for a minute before she finally let me actually fuck her for the first time. She knew my first time I shot off quick from all the times she'd sucked me off. So she sucked my dick first then let me suck her tits and she tongue fucked my as ( something she really got off on ). Then she finally let me fuck her. The first time she had me fuck her from behind, which might be why I've always preferred that position.

Over the next few months she had me fuck her in every position she could think of almost anytime we were home alone. Sometimes wearing some of our moms sexy lingerie or doing sexy strip shows for me. And sometimes even when our parents were home she'd sneak in my room late at night and suck my dick while I played with her tits. This went on for almost two years until she left for college. Which that was wild too. My parents let me take the bus a couple of times and spend the weekend with her and her hot roommate. That was my first time watching 2 girls have sex and my 1st FFM threesome. Though I'd had a couple of MFM threesomes a few years before with my best friend and his sister we were a little older than. Though it was mostly just her sucking us both off but I did get to fuck her once but her brother wasn't there. My sister didn't know but I found out a few years later that our father knew we were having sex, as well as me jerking off looking at her pictures. It turned out he found the pictures in my room and saw pecker spots on them, but had put them back where he'd found them. He'd also got home early one day and was going to turn on the sprinklers and the faucet was under my bedroom window. He saw us on my bed naked and she was sucking my cock then set up and was opening a condom. So he got back in his car and stayed gone a while making sure to make lots of noise when he came back. He confessed that he'd jerked off thinking about fucking her too, and trying to see her while she was naked. But said he'd never touched her. He confessed that to me one night after my wife had stripped for us and we'd taken turns fucking her while she sucked the other off.
