with both parents working it gave us a lot of time at home alone with out our parents which led to lots of fun for us. i've talked before about my sister and me but haven't given all the details before now just for plausible deniability but she's 7 yrs younger than me, things started when she walked in on me looking at porn when i was 15 and asked what i was doing. after trying to claim i was doing nothing and her persistence i explained to her what i was doing and she only wanted to know more.

for whatever reason after she started asking more about things i asked her if she wanted to model some of our moms lingerie for me, with it making her feel like a big girl she loved it and did that for about 15 mins with numerous different items none of which really fit her 8 year old body but that didnt matter. after her little modeling routine became pretty normal we started some mutual touching and me letting her explore some things. this kept up for a year off and on with her becoming more and more curious and me teaching her new things. whenever she wanted pretty much i'd let her watch porn with me and she started wanting to try the things she'd see. after months of the usual she wanted to try oral sex to which i gladly agreed and started teaching her how to give and receive which was something she loved. in order for me to convince her to swallow the cum i told her she could kiss me with it and share to prove it was good which is still by far one of the hottest things i've ever done.

over the first year she had been developing and getting a great set of tits on her which were unbelievably perky and great to play with. about 6 months after this she came to me asking about sex and what it was like. after giving her some sparse details she was wanting to know what it felt like and those kinds of things that aren't the easiest to describe. now why things hadn't gotten to this before i don't know, it definitely wasn't because i didn't want to but most likely because i didn't want to scare her off. i beat around the bush a little bit hinting that maybe she should just try and see for herself how good it feels after the first time. since she wasn't on the pill i put on a condom and went slow and easy to start. once she got used to me being in her i started to go a little quicker which she almost immediately started fucking back and moaning like crazy. that first time we took lots of time and i showed her a few different positions. wanting to feel her without a condom i used the excuse of showing her how it felt when the condom broke and intentionally broke the condom and fucked her for a little bit like that. when i asked her which she liked better with out hesitation answered without the condom.

we continued fucking and fooling around whenever we could when our parents weren't home even sneaking in some fun when they'd take the dog for a walk. i'll never forget the first time we fucked with out parents home. it was Christmas Eve three years later and our parents had gone to bed upstairs and we stayed up for a little bit downstairs. we got in to the liquor and started feeling good, being drunk and throwing caution out the window i started playing with her which in turn made her slide down on to the floor inviting me down. i got my dick out and started to fuck her with out a condom, luckily i had some sense still and stopped and grabbed a condom and finished fucking her. after that we never really fucked with anyone else home but would sneak in some quick feels and fun.

one weekday during the summer about 5 years after it all had started i came home to find her tanning out on our back deck in her swim suit on a towel, faking the caring big brother card i put some sun block on her and told her she wouldn't want any tan lines and undid her top and rolled her bottoms and tucked them in to a thong for her and went back in. seeing her laying there in essentially just a thong drove me wild. i went back out about 15 mins later and told her she should come in and get some water, at this point she had gotten on the pill without our parents knowing. when she did i came up behind her and slipped my hand in her bikini bottoms that were still in a thong and started fingering her which in turn led to us fucking right there in the kitchen no condom and was the first time i came in her, it was the best feeling ever and i've never felt closer to her.

although there were other times that we fucked these were the times that were most memorable, we continued fucking and fooling around until i moved. we've talked about it since and neither of us have any regrets and wouldn't change a thing we did other than have more fun.
