The first time with my sister happened when we were teens. I was stroking my cock after a shower. I had left the door open a bit, and I saw her watching me. I said, "If you want to watch, come in." I thought that would make her leave, but instead she came in and watched. After a bit she reached out and touched the head of my cock. I was so hard and turned on that I asked if she wanted to stroke me. She did, and I started rubbing her little tits and tight ass. Then she leaned down and started sucking me. I didn't last very long at that point and came quickly. She wasn't sure what to do so she swallowed my cum.
