Our lawyer at the time recommended a video of me doing this in case of legal issues latter. To this day I don't know if this was based on legal reasoning or him wanting free porn.Yeah. So I suggest you be on hand on your marriage bed and man-up and hand-guide her black lover's erection into you wife's vagina.
It's like taking the Bull by the horns. If you keep clasping the shaft of his babymaker when he orgasms you will feel it brace strongly and thicken then muscularly jerk when he ejaculates in her.
And if you're really up to it, press two finger-tips up against the softer underbelly of his cock you will be able to feel the individual spurts of his cumload pulsing forward through it and onwards into your wife's stretched-up vagina.
It's awesome and wankworthy in the extreme.
