i lock my legs around his head and keep him coiled against me , and now his fingers are slipping into me , too , two fingers into my cleft , delving in and sliding out , and that move from empty to full to empty makes me whine high in my throat , so he does it again , but more fully , and i throw my head back and arch my spine and i shatter beneath him , scream and gasp for breath and then scream again as wave after wave of orgasm hits me .
