For me, it is such an intimate act watching or knowing my wife is sucking her lovers bbc. Firstly, both myself and ******* have kissed her.
Then her wanting to take her bbc in her mouth and pleasure him, is showing her want to please her black lover. The way she handles, strokes, caresses, kisses and sucks his bbc, she is showing how much she loves ot and adores it.
Then the intimacy of either looking him in the eye as she is pleasing him or looking at me as she looks amazing sucking his bbc.
Finally the act of making him cum, allowing him to choose when and where he wants to cum, submitting to him and allowing him to mark his territory by either cumming on her face or making her swallow his load.
