Outdoors, a horny student, bound and gagged, eagerly awaits her master's command. Her eyes sparkle with anticipation as he unzips his pants, revealing a throbbing, veined cock. She opens wide, taking him deep into her throat, her tongue swirling around his shaft. With each thrust, she moans, her body squirming in its restraints. Spit and pre-cum drip down her chin as she hungrily sucks, eager to taste his load. Her master, pleased with her enthusiasm, fucks her mouth harder, his balls slapping against her chin. Finally, with a grunt, he fills her mouth with hot, salty cum, which she swallows greedily.
