Chating with my stepmom while masturbating on her bed

I casually chatted with my stepmom on her bed, enjoying her MILF allure. Unbeknownst to her, I was pleasuring myself, imagining her on top of me. The surprise on her face when she found out made it even more exciting.

I've been chatting with my stepmom for a while now, and she's always been pretty open about her sexual desires. Lately, she's been hinting at wanting to see me jerk off. So, when I finally decided to take the plunge, I headed over to her place. As soon as I walked in, she could tell that something was up. She knew exactly what I was doing, and she didn't seem to mind at all. In fact, she was kind of into it. She sat down on the bed and let me get started, watching as I stroked my big dick. It was a weird feeling, masturbating on her bed, but it was also kind of hot. My stepmom seemed to be enjoying it too, giving me little nods and smiles as I continued to pleasure myself. When I finally came, she didn't even flinch. It was a weird experience, but a pretty hot one.
