26 [M4A] I watched my brown girlfriend get fucked by her hung white ex boyfriend

im in an open relationship with my brown girlfriend. it was her idea to open it, and shes been fucking a lot of white guys. she loves white guys more than any other race, even though im brown like her, and i've always known that about her. we have no rules who we're allowed and not allowed to fuck. one day she told me that she started hooking up with her ex again, and that he found out about me as her bf and that we're in an open relationship. he told her he wanted to have a threesome with both of us, and we both fuck her, and she loved the idea. i hesitated at first, but i ended up agreeing to make her happy. he came over the next day and him and i met for the first time. he's white of course, very handsome, tall, and fit. i felt so intimidated by him immediately. long story short, i ended up cumming super early on, and they just kept going and i sat there and watched them. they did everything in front of me and i watched like a cuck. i still cant believe it happened and cant stop thinking about it. i wanna chat about everything
