Skinny teen girlfriend's first time with stepbrother's big cock

My skinny teen girlfriend has been dying to try out my big cock for the longest time. She's always been teasing me about it, and I've been trying to hold back. But when she finally decided to give it a shot, I was more than ready. I've been practicing my moves, trying to perfect my technique, and I knew she was going to love it. And boy, did she ever. Her tight little body is just perfect for my monster cock. It fits like a glove, and she can't get enough of it. She loves how it fills her up, how it makes her feel so stretched out. And I love how much she's enjoying it. I can see the pleasure on her face, and it's the best feeling in the world. I hope this is the first of many times we do this. I can't wait to see what else she's capable of.
