An unexpected Sunday morning thought. Eri here. While my sisters are still asleep, I've been cataloging the specific acoustic properties of male orgasmic vocalizations. The pitch variance between a genuine, overwhelming release and a performative one is approximately 2.3 semitones. The most authentic sounds are, unsurprisingly, preceded by the most profound states of desperation. Maki delights in creating that state. Rina mocks it. I simply observe and measure the results. It is a clinical process, much like any other biological study. The fact that the subject matter involves a spasming cock and the subsequent expulsion of semen is merely a detail of the data set. The true fascination lies in the predictable collapse of composure.
