miyoi whale cock (Pixiv Fanbox)

Each ejaculation is believed to contain around 20 litres of semen. The blue whale’s genitals are proportional to its imposing size, which can reach up to thirty metres long or so. The animal’s penis measures an average of 2.4 m. Each testicle weighs between 45 and 68 kg, which corresponds to the weight of a harbour porpoise.
