I've been fantasizing about my step dad ever since I heard him and my mom having sex. I tried not to listen at first, but I my mom was barely moaning and my step dad was screaming the hottest things. He kept yelling "I'm filling you up" and as soon as I heard that, I got so turned on. He's been married to my mom for 3 years and we've gotten along okay. I've been wearing tank tops and spandex around the house and I catch him staring at my boobs a lot. Last night we were watching a scary movie together, alone. I had a skirt on and I went under a blanket next to him. I couldn't tell you what the movie was about. I was so nervous and horny. I moved my hands under the blanket and moved my thong to the side. A few minutes later I gasped a lot and acted scared of the movie. It actually worked. He put his hand on my shoulder.
When he put his hand back in his lap, I grabbed it and pulled it next to me, almost under the blanket. He did lot really notice, but I squeezed it and he squeezed back. I was practically shaking I was so freaking nervous. I started pulling his hand under the blanket. We were still holding hands and I had his hand on my thigh. I started playing with his hand by flipping it up and down while I opened my legs more and repositioned myself so I was more angled toward him. He was really into the movie and I didn't think he was aware of me until I played his hand flat on my thigh and I heard him exhale loudly. I was definitely shaking with nerves at this point and I was crazy wet. I opened my lips with two fingers on my left hand while using my right hand to pull his fingers closer.
