"Runner's high and the feeling of orgasm are very similar," says Rina Hasukawa(pseudonym), a third-year student at the University of Tsukuba. She is a female college student athlete who has been devoted to athletics since she was a student. When she started job hunting, she thought about appearing in an adult video to raise funds. "I don't intend to continue in adult videos for long periods of time. Running for long periods of time doesn't really suit me, haha."
