From Arcanet
A spell which bestows upon the target an excessively engorged erection that will not subside for hours. Climaxing doesn't affect the spell or end the spell in any way. Many an apprentice mage, and purchasers of disposable spells, have eagerly snuck home to try out this spell quite certain the pleasure would be incomparable only to swiftly realize that overstimulation is a torture all to its own.
