Twilight learned a forbidden spell of pleasure, powered by the sun. The longer she stays under the sun's rays, the more her breast would grow, the more ecstasy her breasts would give her. She cast the spell on herself by accident, and despite her attempts to reverse her condition, the rest of her day and night was consumed by increasing orgasmic bliss. Now with the morning approaching and her mind hopelessly addled by pleasure, she stare slackjawed, in awe of the growth that the sun shall soon give her.
