Me and my half sister have been secretly dating each other since 2006. When she turned 20, To be honest with you no bull shit no larp crap! We were drunk and skinny dipping together in some random pool we hopped. I after years of seeing her grow up. Could not believe how cute she was, So I leaned over and pressed my lips against hers. And we started making out. We hooked up in the pool. the following weeks was super Awkward we did not speak to each other for a long time. Finally i said to my self enough i need to talk to her about what happened and knocked on her door. She was changing in to her work uniform, and i asked could we talk. She said yes and we for the half hour she had chatted about things. it turns out she also found me attractive and from there we just started hooking up. I got a Awkward to make sure children would never be a issue and since then its been just normal. Like any other relationship only shes half related to me as we share the same father. We don't make this public to any one we know and as of last year were engaged. We have plans to get get married in secret and just live are life happy. Are parents are in other states and the friends we have now are new and don't know us from shit. So we just say were boyfriend and girlfriend. We plan to keep this secret and never tell are family as they would 100% disown us and more then likely report us to who ever they could to make are life's harder. but such is living this way.. I would not change it for the world as shes a amazing women.. just look at that smile and pare of tits .. fucking gets me every time..
