In the prologue, development, sensitivity, desire, endurance, lust, and awakening, divided into 7 categories, we awaken the sexuality of "Kotosui Seira"! A voice I've never heard, overflowing bodily fluids, an irresistible body! With eyes that seem to crave something, "Seira" gazes with anticipation, and to meet her expectations, a hard endless piston! "Iguiguiguigui" spasming while craving a cock, the lewd woman! "Seira," who obeys any command to receive a penis, has erotic potential far beyond imagination!
