All PInkie Pie wanted to do was insert her erect cock into the small hole that sat in her cupcake. Moan with pleasure as she thrust it in whilst looking at that picture of her friends that sat on the desk. Expecting them to arrive to the pile of cum and join in. But what had happened was Twilight arrived first, a little perkier than usual. "Pinkie?" The sexy unicorn shouted as the moans became louder, nearing the climax. "Pinkie? Are you okay?" Twilight's voice became louder as she pulled the door open with her horn and stared in awe as Pinkie finished up. Thrusts were quick and beads of sweat slowly poured down her face. "Pinkie, what the hay-hay are you doing?" Exclaimed the young pony, she remembered that Twilight was pretty young and probably never had heard of masturbation. "I'm having fun, silly!" Pinkie replied with her enthusiastic attitude as usual. Twilight approached gingerly, strange, Spike wasn't here. Usually Twilight had brought him everywhere, "Pinkie, dear. What in the world are you doing?" Rarity walked in elegantly showing off the newest scarf she had made that was bejeweled. Pinkie's face was stretched with a grin as she stuck her penis into Rarity's tight vagina, thrusting in and out in a quick manner. Resulting in Rarity gasping and Twilight observing the activies only for a dinosaur to come in. Attacking each pony before digesting them and humping Fluttershy.
