Cousin [F] and I [M] used to mess around when we younger

So my cousin and I grew up together, we’re about the same age and used to live just five minutes from each other. She was pretty much my bestfriend throughout our childhood and teen years.

Most of my life I saw her as nothing other than a loving sister but as we grew older, I couldn’t help but notice that she had become a gorgeous young woman with an amazing body. Nonetheless, I tried my absolutely best to never sexualize her in my head, not even on accident. However all that changed, when our aunt moved nearby with her family.

All three families started having dinner together on the weekend. Our aunt had an adorable young child and my cousin and I would spend time with him and play with him every Saturday evening. One day he suggested we play this game he made up, which was basically half hide & seek and half wrestling.
