Making up her mind to escape, she took a step forward, hoping to remove her ass from her son's face, which was currently covered in her meat sweats. But unfortunately for her, her son seemed to have already predicted that she would try to move away and immediately curled his finger into a hook and latched his finger into the inner edge of her anus, like a fishing hook caught onto the mouth of a fish.
And then, with one swift motion, he pulled his hand back, which also pulled her anus, which was hooked by his finger, back with it.
Swish~
The inside of her anus was just as sensitive as the insides of her fleshy rectum, so the moment her inner lining felt something pulling it, it didn't fight the force and went along with it so that it didn't get stimulated any further. And as a result, she automatically stepped right back to where she was with a little tug of his finger, and couldn't move anywhere else since his finger was hooked onto her insides and acted like an unbreakable lock.
