I've detailed it a few times on r9k, including back when it first happened which was around 2017. But the QRD is basically
>Mostly just sibling rivalry kind of dynamic for most of our pre-adult years
>start getting close once we matured more in our late teens, her getting much more cuddly and affectionate rather than the usual rivalry stuff we used to to as a pretty sudden 180 on our usual dynamic
>also generally find myself more attracted to her, mostly because she had a tendency to wear very tight leggings and jeans around me, the worst being those dogtooth ones that were popular back in the early 2010s that made her ass stand out
>mostly nothing happens until she comes to visit one year, for most of her visit not much happens beyond cuddling
>we act playful and teasy but the tension just obviously builds, culminating with her and myself watching game of thrones in the living room one night with her wearing loose but thin pajama pants
>get exceedingly horny and frustrated because they were loose but showed off her ass in the thing material
>try to ignore it and keep things civil, but of playfulness, wrestling tickling etc
>play with her by putting my finger in her mouth and her trying to bit it, until she eventually stops trying to bite it and starts sucking it
>realise the feeling is mutual and we end up making out and pleasuring each other though not sex
We did evcntually have sex later, she was also quite kinky and indulged other stuff like letting me spank and bite her, as well as pee desperation play, wearing tight shiny leggings (we couldn't afford latex but she got some PVC ones that were good enough) and other stuff. Very fun relationship just a bit of a shame it couldn't be more, I don't think I could be with a woman who didn't match her kinkiness
