I find my stepsister in her panties and I can't resist putting it in her

As I walked into my stepsister's room, I caught her off guard. She was changing out of her school clothes, standing there in just her lacy black panties. Her perky tits barely contained by her bra. I couldn't believe my luck. She tried to cover up, but I pushed her against the wall and pinned her there. Her eyes were filled with fear but also desire. I could see it in her movements as she started to grind against me. I grabbed her hair and pulled her head back, exposing her neck while I devoured her lips with mine. Slipping one hand under her panties, I found her wet and ready. Without further hesitation, I thrust my cock deep inside her, filling her up. She gasped as I began to pound her, hitting the wall with each powerful stroke. Her nails dug into my shoulders as she climaxed around me, her body shaking with pleasure.
