She starts slow, her feet dancing around my balls, teasing them, making them ache for more. Then, with a wicked grin, she presses down, her feet massaging my sack with just the right amount of pressure. My girlfriend's footjob is a sensory overload, her feet warm and slippery, her thighs quivering with effort. I feel my balls tighten, ready to explode, but she slows down, prolonging my pleasure, drawing out my orgasm until I'm begging for release.
