Feeling his tight hole adjusting to accommodate more of her massive size, she started shoving more and more of herself into him. She bit her lip, feeling the tight squeeze. Her shaft was throbbing and due to how long it had been since she had been with someone, mixed with the almost unbearable tightness. Pulling her hips back, she shoved forward again, then lightly smacked his ass directly over the birthmark. The throbbing grew faster and faster, and knowing she was about to cum, she knew she had to pull out. With a sudden speed, she pulled her cock out of the hole. Then she flipped him over onto his back. Looking down at her child, she stroked the thick, meaty girth of her shaft over the boy.
