I have sex with my stepbrother after winning in the room, and I enjoy it when his penis goes inside my anus

After winning a game of chess, things took an unexpected turn with my stepbrother. I decided to seduce him, knowing he had a thing for my big ass. I teased him, showing off my curves, and before I knew it, he was undressing me. His excitement grew as he explored my body, his fingers tracing over my skin. I could feel his arousal against me, and I knew what he wanted. I offered him my backdoor, and he took it eagerly. The cool air hit my exposed skin as he positioned himself. His thick member slid into me, filling me up. I moaned in pleasure, enjoying the intense sensation. He continued to thrust, our rhythm syncing perfectly. His hands roamed my body, adding to the ecstasy. The room echoed with our heavy breathing and the sounds of our bodies moving together. This was the best sex I've ever had, and I hoped it wouldn't end.
