It was the morning after Pinkie Pie's Birthday in Sugarcube Corner. Twilight awoke that morning after the party. The pony got a large, clear, shiny and pink cutie mark printed balloon at that party despite that the pony had a balloon phobia. Pinkie Pie went by that sunny sumnmer morning by the open window to Twilight's bedroom. Twilight laid and hugged, kissed and rubbed the creaking balloon in the meanwhile. The horned pony shaked in  both fright and ecstasy by feeling the soft balloon skin brush against her body.

"Hey Twilight." Pinkie Pie said to Twilight and smiled.

"Hi, what a party we had last night." the unicorn said to the pink pony and gave a smile.

The two ponies grabbed and released the creaking balloon in long time, as Twilight got a hornboner by playing with the noisy  balloon. Twilight held the balloon with her hooves, as Pinkie Pie gave the horny unicorn a long hornjob. Pinkie Pie watched as Twilight laid on the side, and rubbed the noisy balloon against her stomach and privates in nearly two hours. At last had the horny unicorn reached her final orgasm that noon.
