Ava's eyes widen in disbelief as she sees the sheer size of the cock before her. Her heart races, a mix of fear and excitement coursing through her veins. She tentatively reaches out, her small hand barely able to grasp the thick shaft. As she strokes it, feeling the veins pulse beneath her touch, she can't help but imagine what it would feel like inside her. The owner of the cock, sensing her apprehension, encourages her, his deep voice rumbling, "Go on, Ava. See how much you can take." Ava takes a deep breath, her lips parting as she leans in, her tongue darting out to taste the tip, her eyes never leaving his.
