GF's sweet, eager mouth is a delicious contrast to her sour, competitive nature. She sucks him off with a fierce determination, her tongue swirling around his sensitive head, her lips tight and hungry. She takes him deep, her throat muscles relaxing to accommodate his thickness. Her competitive streak shows as she tries to take him even deeper, her eyes challenging him. She moans around his cock, the vibrations driving him wild. As he cums, she enthusiastically swallows, a satisfied smirk playing on her lips.
