It was midday in the Whitewood Forest and Big Macintosh was in his black shorts and white tank top. He was ready to get in a good jog before going back to his sister in the fields back in Sweet Apple Acres.
He laced up his black and yellow running sneakers, breathing in and out deeply. Big Mac passed his hand through his mane and ears and then down through his tail. He looked down the trail he had to run and made his first step.
He jogged along the path and met a few other stallions and mares along the way. He kept his nice and slow pace for a while but then decided he want to burn a lot of calories, so he started to sprint.
"Must.. be.. faster," he said, trying to be quicker with every step. He was nearing halfway through the forest when he saw Fluttershy just seconds before crashing into her. His face had came into contact with her boobs, and he fell backwards onto the ground.
"Oh my goodness, I am so sorry! Wait... who did I bump into?" the yellow pegasus mare said, looking around. She didn't see anyone heard mumbling noises from the ground. She took a few steps backwards and looked only to have seen Big Mac lying flat on his back.
"Ohmygoodness Big Mac, I'm so so sorry," she said as she came and sat on top of his stomach. "I really didn't see you coming. Oh dear, I knew I shouldn't have jogged too fast."
Big Mac squinted as he placed a hand to his head, looking up and trying to see who was sitting on him. His widened to the first thing he saw, boobs that were glossy. It was sweat that Fluttershy had accumulated from jogging, but that didn't matter to Big Macintosh. He was completely bent over backwards for her at that moment.
She leaned in towards him and placed her hands under his chin, "I'm really sorry Big Mac. If there was only something I could've done to make you feel better."
Big Mac's penis had erected to its full length, and Fluttershy leaned back on it.
"Oh my," she aloud, moving her hand behind her rear to feel what it was that caught her by surprise. She looked at him, putting a hand over her mouth to hide her smile. She giggled and then looked around and saw no one. "You know, Big Mac. I could relieve some of that tension you have down here. I think it should suffice for me bumping into you and all."
Big Mac looked at her eyes, her seducing stare captivated him within moments. However, he wasn't sure if this was right way to go about.
Fluttershy didn't want to wait any longer and was feeling too horny to let another minute pass by. "Alright, tell me when you decide. I'll just get busy, okay?"
She began rubbing her ass up and down his erected shaft. Big Mac's breath started coming in short pants as she continued, making it feel harder.
Fluttershy stopped at the tip of his shaft. She pulled away her black tight underwear from over her anus and let herself lean in on his penis. Part her pink mane came down over the right side of her face.
"Are you liking what you're getting so far, Big Mac? If you don't, I could do better."
"Yup!" he replied. Fluttershy smiled, pressing herself down on his penis. Its tip, penetrating her anus, begins to move up slowly inside of her.
"Mmmph..." Fluttershy let out, being filled with great pleasure. She came up and went down until had all of his erection within her. Her breath began coming in short pants as she began to ride on him. "This"-pants-"feels"-pants-"so"-pants-"good."
Big Mac only made a short breath through his nostrils, giving approval of her comment. Fluttershy placed her hands on his chest, and she moved her hips and made her ass go up and down, slapping her sweaty booty down on his pelvis area.
"So good," Big Mac said as he felt some of his semen, being squirted up inside her anus. Fluttershy stopped and got up from off of his penis. It was then that Big Mac remembered he had to be back to help Applejack with the farm. He grabbed her by the hand and looked into her eyes.
"I can't spend the whole time. I have to go help Applejack with the apples, so I'm going to make this quick."
He quickly inserted his erection within her vagina, and a small scream left Fluttershy's mouth. He moved and made Fluttershy go down onto her back. He then held up her right leg, putting his other hand onto her left nipple thrusting her deeply.
"Mmph, mmph, mmph, mmph, ah, ah, mmph, mmph, aah," Fluttershy continued as Big Mac kept thrusting, his sweaty body coming against hers. Fluttershy's boobs moving up and down, her pupils moving up almost back in her head, her tongue coming out like a cute puppy dog.
"Ah, ah, ah, mmph, mmph! Mmph, ooooh yeeees, moore, ah, ah," she went on. Big Mac was nearing his climax. With each thrust he felt his climax point coming closer and closer.
"Here.. it.. comes," Big Mac said, cumming inside her and filling her up. Her stomach began to expand and a lot of his thick semen dripped down from her clitoris.
"Mmmmph...."
Big Mac pulled out of her, and he headed back to the farm to help his sister, leaving Fluttershy alone on the trail.
Fluttershy was on the ground, looking up at the sky. She smiled and said, "I didn't reach my climax... but that was a good fucking."
