Twilight had went to bed under the night before Summer Sun Celebration, and her five friends was still up. A year had passed since Twilight had arrived in Ponyville. There was games, spicy cupcakes and strong drinks that hot night in June. Youthful ponies came from all over Equestria that night.to the library. The library had been decorated with many balloons in many shapes and colours, as streamers hanged around too. Rarity that had a hornboner pricked a yellow, clear, round, shiny and big balloon over to her friends by using her hard horn. The five ponies and Derpy felt aroused by hearing the shiny golden round balloon make soft whiny and bumpy noises by being played with even if the ponies was afraid of balloons. Fluttershy, Derpy and Rainbow Dash had a wingboner by playing balloon, and they rubbed themselves under the legs under the play. Then was Pinkie Pie sucking Rarity hot horn in long time, while Depy brushed the whiny yellow sphere against Lyra's head. Lyra felt how the soft rubber body brushed against her head, as she got a hornboner by hearing the loud squee noises from the squeakytoy. At last had Lyra reached her climax by rubbing her hard horn in Derpy's butt in some minutes. Ecstatic Derpy felt how she had the hardened unicorn rod inside her butt. There was dancing to the latest hits, reading of fairytales from books and more after the ponies had their balloon play. The party had ended in the morning.
