Cum Spell

Righty Tighty is a unicorn mare who lives in a cottage a few miles outside of Ponyville. One day while in town she went to the rainbow falls traders exchange. She was browsing when she came across a book that ways to end your heat. She traded all her items for the book and left the exchange to go home. The next morning she woke up to find she was in heat and it seemed to be worse. She went to the book and looked at all the spells.  She saw the easiest one was one of the ones without a title. She cast the spell and waited. She suddenly felt a weight in her womb. When she stood up she felt a liquid slosh inside her. She looked at her belly and saw it was distended and growing. She went to lay down. When she payed down she went to sleep. After a couple of hours she woke up and looked at her belly and saw she looked as if she were ready to drop triplets.
