Teen babysitter gives oral pleasure to well-endowed man

A young, tattooed girl is on the job as a babysitter when her employer's son, a student, walks in. She's not particularly impressed by his appearance, but he's clearly not satisfied with his current partner. He's well-endowed, but no one seems to be able to handle him. The young girl, intrigued by the challenge, takes it upon herself to remedy the situation. She's inexperienced, but eager to learn. The young man is initially taken aback by her audacity, but quickly warms up to the idea. He watches as she takes him into her mouth, her eyes wide with wonder and excitement. She's not particularly skilled, but her enthusiasm more than makes up for it. The young man is pleased, and he continues to guide her until she manages to take him deeper, her throat stretching to accommodate him. The sight of this young girl, barely 18, pleasuring him is enough to make him climax.
