"Mamando a fondo" translates to "Swallowing Deeply," and that's exactly what these insatiable lovers do. No words are exchanged, just hungry gazes and eager hands. She unzips him, her eyes widening at the sight of his throbbing cock. He guides her head down, she opens wide, taking him in inch by inch until he hits the back of her throat. She gags, tears streaming, but she's loving it. He fucks her throat, his balls slapping against her chin, while she moans, vibrations resonating through his shaft. He pulls out, his cock glistening with her saliva, before pushing back in, over and over, until she swallows every last drop of his hot cum.
