We’re not sure why tan lines on a woman aren’t more popular. The contrast on the skin becomes a targeted focal point and they add a little bit of retroactive mystery, leaving an impression of all you’d see if she were still wearing the tiny bikini that made them. There’s something exciting about them, and Monica pulls them off perfectly. Some might say it’s her trademark, but are we missing something? This is Monica Santhiago we’re talking about! You know that scene in Jurassic Park where the T-Rex is coming, and the glass of water starts to ripple? With each step towards your manhood, Santhiago’s thighs and ass make those same rumblings, except even though you’re scared, you’re happy she’s coming. And you should be scared because this weapon of ass destruction is a lot for any man to handle. Even as thick rumps make their mark on pop culture at large, Monica’s booty is literally awesome. Brazil generally has an outstanding reputation for exotic babes with incredible backsides, but this one really is so phat that you can see it from the front. ‘Bubble butt’ doesn’t begin to cover it. It’s so big and plump that you can actually hear it thumping from the pelvises slamming against it. And there are no “buts” when it comes to this butt, since Monica really knows how to use it, absorbing the biggest porno schlongs with ease. And the rest of her is also just as sexy. From her devilish squint to her small waist and cute titties, she is a sight to behold… and an ass to behold twice – once for each cheek.
