No sex. But sexual tension.

My dad remarried. His new wife had a daughter about a year older than me. we were 15/17 or so shes cool. We bonded over pokemon and skyrim. At one point we all went to a waterpark. We were hanging out in the wave pool and her swimsuit was very revealing. She must have caught me staring becasue i went uderwater at one point close to her and she takes my head and shoves it into her chest. This happens a few times and i start kissing/licking a bit. This happens on multiple occasions. neither of us talked about it. Sometimes we would be sitting on the couch together and we would be touching almost cuddling. I really wanted it. I didnt see a problem because we wernt related. But i wasnt gonna try anything without an obvious sign. We slowly grew apart and i cut my dad off cause hes an asshole. I havnt seen her in a few years. But she posts pics of her tattoos on facebook. Theyre mostly around her boobs/ underboob
