WANZ-644 Tsubomi, a professional child-making instructor who teaches you how to impregnate 100% using your own body

This is the Tsubo Pregnancy Clinic, which is run by ``professional child-makers'' who use their own bodies as practice grounds to instill the latest infertility treatment, which has not yet become popular in Japan or even Europe and the United States. The curriculum starts with the collection of semen samples, which is strictly a medical procedure. Everything from guidance on insertion angles to perverted manipulative sexual intercourse techniques using yoga techniques and advanced techniques such as understanding the appropriate ejaculation position.
