I was surprised and impressed to see Haru Shibasaki, a second-year graduate, struggling to develop a concept masturbatorium. Her willingness to overcome her shyness and use her own body to do research was amazing. I salute her for her hard work. Keeping in mind that the purpose of this product is to develop onaholes, I am curious to see what the research results are.
