"Whosoever wears this magical condom will notice nothing odd until their Manhood is inserted into a vagina. Once inside, the condom will cause the Manhood to increase in circumference by (2d100)%. It may be necessary to consult Vaginal Circumference Potential and Ripped Orifice in Chapter 2: Body. This enlargement will feel pleasing to the male, but painful to the female. It will be impossible to remove the Manhood from the vagina until after ejaculation."
