The thrill of the unknown sends shivers down her spine as she wraps her lips around the thick, veined shaft. She moans softly, the vibrations causing the black stallion to twitch in her mouth.

She obliges, her head bobbing furiously, saliva dripping down her chin as she devours the cock, her own pussy soaking through her panties with each delicious slurp.
