YNOT – Busty MILF Kelly Madison and her husband Ryan have been entertaining fans at their virtual home for more than a decade. The award-winning website is well known for its frequent updates … but who knew the Madisons had been posting new material at the average rate of 90 scenes a year?

Now everyone does. This week, KellyMadison.com celebrated its “Naughty 900th” episode.

In honor of the milestone, Kelly Madison enlisted the aid of two other busty beauties to assist in seducing Ryan Madison. The poor man was shocked and appalled that his wife would pull such a sneaky trick, but being the good sport that he is, he played along.

“I can’t believe I have done 900 scenes for KellyMadison.com and almost 500 scenes for my other two sites, Pornfidelity.com and Teenfidelity.com,” Kelly Madison said. “Wow, what a slut I am!”

The 900th scene bears witness to that open secret: Madison searched for and found the largest natural breasts in Southern California. Just to make sure no one is faking their enormous rack, the ladies check each other out before Ryan Madison joins them. Suffice it to say no one leaves the adventure less than completely satisfied — especially Ryan, who manages to perform four money shots before the cameras stop rolling.

The scene is significant in another way, as well: It’s the first foursome to appear at KellyMadison.com, which heretofore contained only solo, boy-girl and threesome scenes.

All of Madison’s membership websites are part of the KellyCash affiliate program, which pays 60-percent recurring revenue share or $25 per sign-up.
