Isn't it great to watch you wife passionately kissing a black man as he methodically fucks her. Then, after he cums, he stays in her so his seed has no place to go but deep into her willing mature white body where you all want it, once again demonstrating the sexual superiority of black men over white men.
Oh YES!! Stay coupled, kissing and cuddling. Let him see not only the physical lust she had to receive your penis and sperm, but let him watch the emotional connection develop and he realizes that she is becoming attached to another man. By the time he slips in to enjoy the silky seconds, all three of you should know that - if she is fertile - the conception has already taken place.
