After a couple of sessions introducing Skye to the tickling kink, I step up the intensity, bringing out 3 different hairbrushes and the electric flosser plus a heavy helping of baby oil. All of the hairbrushes drive her into a crazy fit of screams and thrashing but it's her underarms that are the worst spot by far and I take full advantage of this.

While she's blindfolded I keep one hand lightly tickling her feet while I slowly creep towards her upperbody, catching her off-gaurd multiple times. A ballgag is added halfway through the video to heighten that sense of helplessness.
