She's a dominant force, her lithe body writhing with a hunger that can't be sated. Her GF loves to tease, to test her lover's limits. Today, it's all about cock-and-ball torment. She starts with a firm grip, her nails digging slightly into his flesh. Then, she uses her teeth, gentle but firm, making him squirm. She spits on his cock, rubbing the saliva in, before taking him into her mouth, only to pull back, leaving him aching for more. She knows what she's doing, and she's enjoying every moment of his discomfort, his pleasure.
