My girlfriend, a petite, innocent-looking vixen, gets on her knees, her big, doe eyes looking up at me with an unspoken promise. She parts her plump lips, her tongue darting out to lick the head of my throbbing cock. I watch, mesmerized, as she takes me in, inch by inch, her throat relaxing to accommodate my length. She's a pro at this, her head bobbing up and down, her hand working the shaft in tandem with her mouth. She pauses to lick my balls, her other hand playing with them, before taking me back in, her lips tight around me. I can feel my orgasm building, her relentless pace pushing me closer to the edge.
