My stepbro's girlfriend gets satisfied by me while he's immersed in gaming

My stepbro is a huge fan of gaming and his girlfriend is always busy with her work. So, when he wants to spend some quality time with her, he just starts playing games. But, as a good guy, I understand that it’s not enough for him, and sometimes I help him to satisfy her sexual needs. That day, when my stepbro was playing his favorite game on his computer, my stepbro’s girlfriend came to me and asked for help. She wanted to get satisfied, but her boyfriend was fully immersed in the game. So, to help her, I started fucking her right in front of my stepbro. It was a kind of a taboo for us, because we are from different races, and it’s not usual for us to have sex. But she was a real sex-starved bitch and she enjoyed every second of our fucking. It was a real family fuck for us, and maybe one day my stepbro will appreciate my help in satisfying his girlfriend.
