This is me exactly. I love playing the part of Cuck but in reality I'm a very dominate person. We're more of a Stag/Vixen couple but we like to play roles when it comes to sex and fun stuff. Here's my first experience watching my wife, and its not even the sex part yet. That Happened shortly after this experience, like 10 minutes later.
The feelings you're talking about was still something I had to deal with but i think it's part of the whole excitement around it. You want to see and experience it all but that very first visit after the talking is done and rules are agreed on, then fantasy turns into reality with the first time you watch your faithful, devoted wife drop to get knees while he's sitting on the couch and she slides her lips around that massive black cock, you get jealous beyond words but you're so turned on because she's actually sucking another guys dick.
Then as you watched as she gets more comfortable with his dick in her mouth, she really started blowing him, making his head go back, hearing him say "Ah fuck girl this ain't your first time sucking black cock is it? Damn girl you gonna make me cum." Then he puts 1 hand behind her head and is guiding her up and down that huge black cock, while you're thinking in your mind, Damn she does know how to suck that huge cock really really good.
Then he puts both hands on her head guiding her up and down, guiding you wife's gorgeous face and lips farther and farther down his thick black cock with every repetition. You wonder how she's able to get that much of his cock in her mouth, then you realize it's not just in her mouth, she's getting part of it down her throat.
Then he starts holding your wife's head and perfectly fixed hair with a harder grip and starts pausing every time he gets his dick all the way in her and buries her beautiful lil face and eyes up against his stomach just for a second or 2 each time, forcnng her to control her gag reflex.
Then he starts moving her head up and down harder and faster while you watch your beautiful bride get face fucked right in front of you and she wraps her arms around the bottom of his waist and willingly let's him continue to do it, in your own living room, on your couch you and everyone else sits on... and you know what's about to happen.
Then he pulls her pretty lil face and her completely messed up hair hard against his stomach and you see his face suddenly have that look of PURE PLEASURE and contentment as he starts to moan loudly with his entire massive black cock down the love of your life's throat while he's unloading throb after throb of his pent up manhood down Your Baby's throat into her tight, white lil tummy. And all your wife does until he's done cumming down her throat is willingly stay in position, he's not even holding her down, making lite moans with every throb of his dick down her throat. Then when he's done she slowly comes up, tears running down her face from holding back her gag reflex, and she asks HIM if that was good.
You're marriage is forever changed now that you just watched him dominate your wife and she'll always have that experience of feeling HIM balls deep into your marriage as he unloaded and filled up her white lil tummy with a full serving of his Black Seed that made her feel full and satisfied with it inside her white, beautiful lil body.
Then the sex happened and lasted for almost 3 hours.
