TL;DR: girlfriend and I tired with a another couple, the husband came and his wife got angry and called the whole thing off

So my girlfriend and I tried again with another couple tonight and it started off great. We talked, was enjoying each other company, etc. Eventually we put on music, we begin getting sexy. The wife of the couple started fingering my girlfriend and rubbing my dick, we start started stripping, and she starts sucking my dick in front of my girlfriend, who she knows has a huge cuckqueen fetish. She says "Ever see a white girl suck your boyfriend's dick?" (Now I'm not sure if I'm into all the race play she had going on but we tried to ignore it) my girlfriend tells her no, and she start deep throating me hard, now mind you I'm 8.5 inches and have quite some girth, but she was handling it like a fucking champ. The husband starts fingering both his wife and my girlfriend. I tell him to also slap her ass as she likes it. Soon his wife is riding me, having my girlfriend and I call her "white slut" and stuff (again not sure if we are into this, has anyone else dealt with a couple who did this?) I then position her in missionary and start fucking her hard, the husband is struggling to stay hard as it's their first time with a couple and he is usually a cuck, but he soon gets hard and has my girlfriend in doggy style, and everything is going great. However I had to go to the bathroom, but when I game out, it seems the wife thought the husband had came (we were wearing condoms) and got mad, and basically called the whole thing off and left. So yeah 2nd time around and had a little bit of drama
