Vaginal Eels
A Sexually transmitted disease in which mold ferments on your Fallopian tube and wriggles out into your uterus. It travels in waves, causing defected babies. In males it results in a clogged urethra, preventing ejaculation and causing excruciating urination.
One time, I spilled some mold dust on my dick and fucked a girl. She woke up with vaginal eels. I have urethrian eels as well.
