My Wife [27] her first time fucking another man. Not how I [28] expected it to go…

Me (28) and my Wife (27) had our first real cuckold date yesterday, we had something planned for over 2 weeks but he canceled 2hours before… we arranged a last minute date but it wasn't what i expected it to be. Guy wasnt really our type but she was too horny and couldnt let him go… My wife likes dominating me and it was supposed to be a bi cuckold date but it turned out just her getting fucked and sucking Dick for 2 hours and me not even getting hard. He came to our hotel room and i went for drinks after 10min or so… I came back and she was already on him kissing him deeply while he was groping her ass. Only time I really got involved was when she asked to lick her asshole when they were fucking doggy, licking her when she was blowing him and when he came inside her for cleanup. We've been having fantasies about a "bi sissy cuckold" vibe for so lang and i just hoped i would be more involved "helping" her.. we talked and she understands but doesnt know how to make sure it goes different the next time. I'm fantasizing about sucking cock for her for so long but it feels a little bit that i chickened out… she asked if she could invite someone else for tonight because it made her so horny and I told her I'm not up for it.. for years it was me wanting my wife to fuck other men and know when she finally did it I seem to back out… I loved watching her enjoy him but it just feels weird or something. Any advise would be awesome!
