I recently got married and my new wife has a daughter from her previous relationship. We have been getting along really well, and I have been enjoying spending time with her. The other day, we were all hanging out in my parent's house and things got a little out of hand. My wife went to the store and left me alone with my new stepsister. I was trying to be a good stepdad and keep an eye on her, but things got heated up when she started flirting with me. Before I knew it, we were in my parent's bed and she was giving me a blowjob. It was so hot that I couldn't help myself and I came inside her. It was a crazy experience, and I can't wait to see what happens next.
