As a black bull having been involved in many wife sharing/cuckold relationships I love taking a woman in her marital bed with the hubby/bf watching... it seems to make them hot too!!!
The whole body contact - her wrap-around legs - the kissing - they obviously WANT to make a baby! Wish we could have seen the insemination, and hopefully they stay coupled, kissing and cuddling, after he finishes twitching.
