Kairi jerked forward as much as her position would let her when she felt John's touch along the folds of her slit.  He kept moving his fingers over her and she tried to stifle her moan but the gag prevented this.  She shivered the sensation sending little waves of teasing pleasure through her.  She thought she could stifle her desire but she could feel her self moistening under his hand.  Her face reddened in shame and she was glad he couldn't see her face.
