John Doe, engrossed in his morning jerk-off session, is startled by his stepsister Michelle's sudden entrance. Her eyes lock onto his throbbing cock, and she can't resist the urge to taste it.

John, now fully awake and horny, grabs her hips and pounds her mercilessly, pulling out at the last second to coat her stomach with his hot, creamy load.
