Get your minds out of the gutter!

Luna leans over and touches the tip of Spike's shaft with her horn, whereupon it instantly vanishes and he feels an immense relief. "Thank you." He says grateful that the throbbing rod which has graced his loins for most of three hours is gone again.

"Now you need to learn how to Re-Manifest it again if you want to have sex with your beloved Rarity." She says picking up her tea again with her telekinetic powers and sipping it.

"You, you know about that?" Spike asks timidly.

"I am the Princess of Dreams as well as the Night: and yours have been quite romantic where our current bearer of the Element of Generosity is concerned. Not only that but as of tonight incredibly erotic as well. Though you don't remember them that was why you woke with your Penis manifested." Luna declares.

"Hu, how do I make it come back?" Spike asks, timid.

"Just concentrate on something you find sexy, like Rarity with her private's manifested." Princess Luna says without batting an eye.

"Ok..." Spike says and concentrates on that image, though it's hard because he has never SEEN Rarity with manifested genitals... After a minute though the sensation of his erect shaft returns and he looks down on it again. "So I know how to make it appear, but how do I make it disappear? I can't come see you every time I need to get a boner to go away." Spike says pleased and more confident.

"That's harder..." Luna declares. "You have to find one or more images, memories or sensations which completely turn you OFF and concentrate on them, it usually takes some practice. The other way is to masturbate to climax, when males do that their Genitals de-manifest automatically once the last of the semen is out." Luna explains, as if this were nothing new, then comments: "You haven't touched the sapphires, rubies, and emeralds I have been saving for when this happened..."

"Sorry, they look delicious but I have been a bit distracted..." Spike says plucking two rubies with his fingers and thumb and popping them in his mouth. As he chews and Luna sips her tea, refilling it from the teapot with a telekinetic hand, spike concentrates on some of the just awful hate-mail Twilight has received since becoming princess, which in a few cases has gotten graphically violent, and about a minute later his erection vanishes.

"Good, you're ready." Luna declares with a smile. "I will send a phantasm of this new you waltzing into the erotic dream Rarity is having but it will be up to you to capitalize on that, and I will only help you so this once: after that you are on your own my young draconic subject." Luna informs Spike, and rings a little bell. Soon a Bat-Pegasus woman in a maid's outfit appears and Luna tells her: "Bring my personal carriage around, we need to get Master Spike home, and he cannot fly nearly fast enough yet."
