Just This Once

“Alright, I brought some games to help us get a little more comfortable if we need it.” Rainbow Dash grabbed her saddlebag and started rummaging through it. Applejack placed a hoof on hers and stopped her.

“I think we’re a little past games by now, sugarcube. Besides, weren’t you in the middle of something when I walked in?” Applejack’s eyes wandered over to Big Mac as a soft grin spread across her face. Rainbow Dash lifted her head up and smiled across to Big Mac. She leapt across the room, landing with her snout just under his balls. The sudden contact made him squirm, but only a little, quickly settling into the feeling of Rainbow Dash nuzzling his scrotum.

He watched his wife cross the room to his sister. Sugar Belle smiled and placed a hoof on Applejack’s cheek, pulling her into a soft kiss. Along with the visual and physical cues, the smell of mare musk soon filled the room and Big Mac began to be overwhelmed. His cock rose to full height quickly and Rainbow Dash began licking her way up his shaft. At his head, her tongue swirled around his flare once more. He loved that feeling so much, especially when he got to watch his wife and sister make out.

He began to absentmindedly thrust into Rainbow Dash’s mouth while he watched the two most important mares in his life. His flare was teased, then his sister moaned while Sugar Belle worked her magic on the neck, then the musk filled his head as he tried to take a breath. “Rainbow, I’m—“

He guessed it was enough warning. She braced her body and he felt her lips lock around his tip as the first shot exploded out of his cock. He grunted, throwing his head back on the couch. Each shot was followed by a quick swirl of Rainbow Dash’s tongue around his cock head. He didn’t know how long it took for his dick to stop pulsing, but he could barely lift his head when it did. With one last swirl of her tongue, Rainbow Dash pulled her mouth off of his softening cock. Then, a tap to his belly forced him to lift his head and look.

There between his legs, Rainbow Dash sat with her cheeks stretched out farther than he thought was possible. Once she knew he was watching her, Rainbow Dash stood and walked over to Sugar Belle. They pressed their lips together and Rainbow Dash fed his cum into Sugar Belle’s mouth. When about a third of it was shared, she pulled away and moved to Applejack. She placed her hoof on Applejack’s cheek and gently pulled her in to meet her lips. Applejack moaned softly as Big Mac’s cum was pushed into her mouth.

When half of the remainder was gone, Rainbow Dash pulled away once more. Big Mac looked over at his wife. She showed him his cum in her mouth before swallowing it for him with a smile. When he turned his attention back to Rainbow and Applejack, his sister had turned toward him and began walking up to him. Her cheeks were still bulged with his cum as she sat down in front of him. Their eyes met once more and she swallowed.

Big Mac dove down and pressed Applejack to the floor in a deep kiss. His tongue invaded her mouth, tasting himself and her tongue in the process. She wrapped her hooves around him and held him tight, not letting move away. Big Mac felt his cock begin to rise once more and soon it was pressing against his sister’s sex. She gasped and broke the kiss, staring up into his eyes.

Big Mac thought about his wife sitting three feet away. He thought about Rainbow Dash staring at them after giving him a great blowjob and swallowing his cum. Then he thought about the moist heat he felt at the tip of his cock. Without breaking their eye contact, he asked, “Are you ready, AJ?”

Applejack took a deep breath and nodded, bracing herself to receive her brother’s massive cock. Big Mac leaned down and kissed her once more as he pushed forward into her most intimate place. Applejack let out a grunt and Big Mac froze, lifting his head and watching to make sure she was okay. After a second, she looked up at him and nodded for him to continue. Big Mac continued forward and soon hilted himself in his sister.

He looked into her eyes as she looked into his. A smile spread on his lips that she mirrored. Then she chuckled. He chuckled in response. Then they were both chuckling and soon laughing. Big Mac pulled his sister up into a hug as he sat up and his cock fell out of her pussy. They leaned back on the couch together and laughed in each other’s hooves for a few minutes.

When they calmed down they smiled at each other before looking across the room at the others. Sugar Belle was smiling softly with watery eyes, but Rainbow Dash looked confused. She glanced back and forth a few times between Applejack and Big Mac before finally throwing her hooves up in the air.

"What was that?! It was super hot until you started laughing."

Big Mac tightened a foreleg around Applejack and gave her a soft noogie. "Well, we are siblings." Then they both began to giggle again.
