Unexpectedly engaging in sexual activity with my stepsister following her provocative behavior in the kitchen

I was cooking in the kitchen when my stepsister, who was feeling a bit naughty, decided to sneak up on me and playfully tease my cock. I wasn't particularly fond of her, but I found myself getting aroused by her provocative actions. My stepmom, who was supposed to be out at a meeting, had left us alone in the house. As I was about to push her away, she took off her clothes, revealing her beautiful body, and then started sucking my dick. It was a crazy moment for both of us, as we had never been in such a situation before. We were both aware of the taboo aspect of our actions, but we couldn't resist the intense pleasure that we experienced. It was a wild and unexpected encounter that left us both wanting more.
