April

Cheerilee and Sweetie Belle were together by themselves in the Ponyville school after the yearly Hearts and Hooves Day. Blue round balloons, heart decorations and banners hanged around in the decorated classroom that afternoon. It had been three years ago since the CMC had been tricking Cheerilee and Big Mac together at Hearts and Hooves Day with a love poison they mistook for a love potion.

"Let me give you an education in Hearts and Hooves Day." the teacher pony said to the filly and smiled.

The pony blew air in a blue, clear, shiny and round balloon for the filly. Soft creaks and hisses came from the balloon that the two ponies were afraid would pop loudly. Sweetie Belle were frightened by balloons, but her hard horn tickled too by seeing the ecstatic pony blow air in the glittering balloon too. The little pony got a hard horn by hearing the swelling balloon creak, and then  were the two ponies pushing and kicking to the balloon in over an hour. Later on had Cheerilee been sucking horny Sweetie Belle's horn in long time, as the little pony inflated and deflated a pink balloon. Sweetie Belle reached her orgasm by having Cheerilee give her hot horn a long massage with a pink creaking balloon until late in the evening. The days were then passing as usual in Ponyville that spring. Until that summers day where Sweetie Belle got a message from Cheerilee after school.

"Your sister, Vinyl Scratch and Octavia will see you and your three friends including other stars at the annual talent show here in Ponyville." the teacher pony told the filly and smiled.

It must had been something special, as the three fillies had not been at that contest for ages.
