The Nympho and the Cuckold

Adults only.
The trophy wife's old workaholic husband cannot keep up with her hyperactive sex drive, leaving her forever horny, so his four horny sons get the hottie drunk and seduce her in a wild marathon orgy. But, having unleashed her inner slut, the four brothers now have to step up their game to keep her satisfied -- all without daddy finding out. Then one of them (no one knows who) gets her pregnant, and now they're all screwed.
