Hmong Br0ther and Girlfriend

So Cua came over last night. We were all in the livingroom watching Netflix. They had a blanket over them, while I was on the recliner. I knew she was touching my br0ther because the blanket was moving. At this time, I wasnt excited or anything, more uncomfortable. My little br0ther (18) was sitting on the floor probably realized it too and walked to his room. After finishing the first movie, Cua got up go to use the restroom and when she got up, you can see my br0ther's hardon. It was so obvious that they were doing stuff because his blue shorts were lifted up all the way up and the outline of his hard cock was evident.

At that point, I pretended to close my eyes as if I was taking a nap. I kept my eyes open just enough so that I can take peeks at this huge hardon. Cua came back from the restroom and right when she got to him, I could see him grabbed her coochie while standing next to him. He made a motion with his head for them to go to his room. She led the way and he got up to follow. At this time, he had to pull his shorts down to cover his legs, but the hardon was still showing.

They got into the room and locked it, and I knew that they were going to go have sex. I got up and sneaked up to the door and peeked under the door. You can see my br0ther's short and her short and blouse on the ground. I can hear her moaning more than his, but she kept talking in Hmong to don't moan so loud. He kept going at it and I can hear his breathing. At this point, I was very very wet. I didnt want my younger br0ther to catch me so I went upstairs to my room and finish me off.
