"Pay attention, I will only give you this lesson once and if you fail you will have to pay for private tutoring." His body moved in a fluid like motion settling in the crevice between Ambrosias legs. "Friction... is the force resisting the relative motion of surfaces sliding against each other. There are several types of friction." He said while one hand abrasively moved along Ambrosia's inner thigh. Galvins hips bucked and moved in a circular motion around the lump he sat on. "For example..." He lowered himself for a dip running his rump along the seam in the middle of the pants. "Dry friction..." He twisted so he could see the others face. Using one of his hands he brought the pale chin forward and licked along the surface of his neck he could reach. "... lubricated fiction... and if you want to learn more I suggest you fork over another greenback."
