A husband abstains until his wife's ovulation day for timed conception. The night before, her beautiful childhood friend cooks fertility-boosting food, and a month of restraint makes him erect. After his wife falls asleep, the friend reveals that she noticed and suggests edging may store even more semen. Claiming oral does not count as cheating, she licks from head to balls and asshole, repeatedly brings him to the brink, then deep-throats him until he releases the huge load meant for making a baby. Unable to forget her tornado-like technique, he begins asking for oral the day before each attempt. Soon the affair escalates into sex, dragging him into a forbidden abyss.
