Been approaching my wife about cucking all wrong... Til last night

For the last two years, I've been occasionally bringing up the topic of bringing another guy into the bedroom, but every tune, she says the idea does nothing for her, and she wouldn't even talk dirty to me about it. She said the idea just didn't appeal to her, so she couldn't get in to it. So last night we were laying in bed and somehow the topic of swingers clubs came up. I asked her if she would ever want to go to one, and she (knowing my fantasy of wanting to have a MMF threesome) said she wasn't turned on by the thought of two guys at once. So I said really, it's just about getting to watch you with another guy. She immediately turned to me and said "really?! You would be okay with that?" I said yeah, and asked if that idea turned her on, and her exact answer was "fuck yes!" After talking about it got another few minutes, she abruptly told me to get her rabbit out of the nightstand. She slid it in without needing any lube and asked me what I wanted to see him do to her. After no more than 10 seconds she had an incredible orgasm, ripping the fitted sheet off of the mattress. I was jerking off at the sme time and came immediately when she did. She got a towel and cleaned me up, then we fell asleep, both feeling incredibly satisfied. That was just last night, so I'm dying to know where we go from here. My wife is black (I'm white), and I've asked her before if it's true that black guys have bigger cocks. Without hesitation, she said "absolutely!" I have a feeling if we turn our fantasy into reality, I know what kind of guy she is going to want to try first! I'm not tiny (7" and thick) but I doubt I can compete with some of the guys out there.
