A, Bit Of Big Brotherly Help

Big Macintosh rolled his eyes, as Apple Bloom begged; "Please Big Mac it'll only take ah sec!" He sighed heavily "Apple Bloom ah can't right now, ah'm busy" He told her softly once again. Apple Blooms, friends Scootaloo and Sweetie Belle walked up beside her. "Did he say yes?" Asked Sweetie Belle. "Nah he said no, he ah's busy!" She complained. "Fine!" He shouted, startling all three of them. "But only for ah sec" He said sternly. For today Big Macintosh had to clear forty three apple trees in an hour; due to Apple Jack having to go on some adventure to a Olympic stadium or something. He walked lazily with the three over-exited fillies to their tree house. Stepping up the stairs to the door he asked; "So, what kinda' project ya'll doin' now?" "Oh we will tell you inside" Scootaloo said quickly as they opened the door. As Big Macintosh walked into the small room he noticed various pieces of magnifying equipment. Also loads of clip boards and cups. "What's all this here fore?" He questioned. "OK Big Mac you sit there" Instructed Scootaloo. "Alright...." He responded warily. "OK it says here the Stallion must first get into a comfortable position" Said Sweetie Belle rightfully. "Do ya'll mind tellin' me what the hay ya'll are doing!" He mustered with a grunt, for he needed to get back to work. "Big Mac, we are doing a project on the...hey Sweetie Belle what is it again?" Asked Apple Bloom while Scootaloo got a clipboard and a pencil. "The Stallion penis." Corrected Sweetie Belle smartly. Big Macintosh gasped "Wait what the hay do ya'll need me for!?" He boomed. "Well it says write a report on the way the penis works and if we were to do a report...why not do it with a real one. Also instead of doing it with somebody else, why not ask somebody we are familiar with?". He put a confused look on his face "So....wait, no, no, no I can't do this you fillies are way too young, what the hay does Mrs. Cherilee think she is, teachin' you three about this!" "I don't know she told us to do it" Was all Scootaloo could manage to say embarrassed. "I can't do this with you three!" He shouted. "OK, wait, wait it says first we need to draw a diagram of the Stallion penis first." Said Sweetie Belle. "OK Big Mac, where is your thing?" Asked Apple Bloom, looking around his body; then spotting the large piece of Stallion Hood, between his legs. Before Big Mac could respond; Apple Bloom touched it with the tip of her hoof, causing Big Macintosh to shudder with pleasure. "OK Sweetie Belle write that down, touching the penis makes the Stallion make weird noises, Big Mac watched as Sweetie Belle began furiously writing down notes. "Do it again" Commanded Scootaloo, Apple Bloom listened and gently stroked his now hard penis. Big Macintosh once again moaned, as she continued. "OK he keeps making weird sounds" Apple Bloom told Sweetie Belle. "Apple Bloom STOP!" Roared Big Macintosh. "I'm your big brother, it aint' right for a filly of your age, or any filly for that matter" He snapped. "Sweetie Belle right that down also, the Stallion gets angry." Big Macintosh forced out a muffled laughter, placing his head on his hooves. "OK we are done the way it works, now it says, the Stallion penis Ejaculates...." Trailed off Sweetie Belle. Big Macintosh raised his brow. "What now?" He asked. "How do you make it go?" Said Apple Bloom poking around his lower area. "It says the Stallion has to do it." Sweetie Belle told Apple Bloom. "OK Big Mac, make it go here use this cup." Apple Bloom instructed Big Macintosh
