My girlfriend wants two BBC

my girlfriend told me a long time ago that he wanted to do a threesome. He wanted to have two black cocks inside her. I have not had any issues with this, I’m quite liberal. So I proposed to my roommate to do a threesome with her. He accepted the proposal, and after being out to dinner with her, we went back to my house. We entered the room and I started to kiss her. When he was excited, my friend came and kissed her from behind. She was overjoyed. My girl is put on all fours and gave us the blowjob, like a good girl. Then, while he sucked still the cock of my friend, I fucked her from behind. Then he has ridden the cock of my friend while I masturbated.
