Twilight went to Pinkie Pie's Birthday party in Sugarcube Corner one hot May evening. Rainbow Dash and Applejack  were there too.

"Welcome everypony to my party." Pinkie Pe told her friends and smiled.

"I will also welcome Twilight that just moved to Ponyille last week." the pink pony said to her friends,

The late night went on with music, dances and games. Twilight, Rainbow Dash, Applejack and Pinkie Pie played balloon together in long time. The playful ponies played with a pink, big and clear thick balloon they pushed to with their snouts.

"This is a freeze spell that I learned from Starswirl the Bearded's book." Twilight told her friends.

Twilight stopped the pink balloon that hanged in the air without moving. The horny unicorn rubbed her warm horn against Pinkie Pie's butt, as Applejack and Rainbow Dash kissed and hugged the freezed balloon in long time. Loud creaks came from the freezed balloon that Applejack and Rainbow Dash kept on petting, as the ponies got aroused by hearing the balloon creak. The ponies were afraid of balloons, and also ecstatic too. Later had Twilight reached her orgasm by having her horn up in the pink pony's butt, as the ponies felt lazy and horny in the hot summer night. The unicorn freed the frozen balloon that the ponies kicked to for a while. Thereafter were there stories, speeches and other games in Sugarcube Corner till the early morning.
