The teen's eyes widen as she takes in the size of her client's cock, a mixture of fear and excitement coursing through her veins. She tentatively takes him into her mouth, her tongue swirling around the tip, tasting the salty pre-cum. He groans, guiding her head with his hands, fucking her face with increasing urgency. She gags, her eyes watering, but she's committed now, her body aching with a strange, new desire. She feels his cock throb, his hot cum filling her mouth as he grunts his release. She swallows, feeling a sense of pride and accomplishment.
