Miaren's breath is warm on Fern's breast as she begins to pant softly.  Both her vagina and her anus tense, quivering with the conflict of keeping things out or holding them in.  More than once, she feels Fern's fingers gripped lightly by her slick walls, and she constantly feels the resistance of the plug.<br/><br/>Whether she tenses or relaxes, that intrusion remains as deep as ever.  The only difference is how its weight presses against her insides.  Both Fern and Adamion will be able to see the brush moving up and down with each contraction of her muscles.
