Little Defeat (Pixiv Fanbox)

*updated* So she invited you to a little swim competition that she has. She has been bragging to you about how she is going to win first place since she is the fastest from all her friends. Well but what if she loses? “Im not going to lose you idiot! I’ll get first place, you’ll see!” She said with a smug smile with her arms closed. Well if she is so sure about it then you both should make a bet. If she wins you will take her to the ice cream shop to have her favorite ice cream after the competition. “And sex!” She exclaimed. “What? No way you worm.” You told her. “Yes!” She yelled back. Alright. But if she loses it will be anal (she hates anal). “Ew! No way, anal sucks! You are the only freak who likes anal!” She yelled at you. “Im not going to give you something that you like if you lose you dumbass.” “Fine! I’ll win anyways” she laughed at you. So the competition started and she was in first place. Every lap she was ahead of every other girl. Everyone was cheering and you were watching in defeat as the final lap was developing. She reached the end of the pool and propelled herself backwards to swim to the finish line. How is she so fast! You were crossing your fingers, there was just one girl inches behind her. It was over, there is no way that other girl catches up. You sister was about to touch the finish line but in the last second something happened. It seems she stopped! The other girl behind her extended her arm and touched the finish line first. Everyone got up and cheered including you. You jumped from your seat and started cheering that random girl that won. You were celebrating your sister’s defeat, clapping and laughing. She got second place just half a second before the other girl. Seems there wont be ice cream for her. You went down with a towel and covered her. You started laughing in her face. “You lost idiot!” You mocked her laughing. “Shut up virgin! She cheated, I didn’t lose.” She said while drying her hair with the towel. “You still lost! Guess who’s not gonna get ice cream.” She looked you with a pouty face and grabbed your hand. She started dragging you in between all the other girls and their families. “Where are we going? You cant stand been seen in complete defeat?” You said. “Shut up.” She replied. You went behind the stairs into some hidden door. She opened it and pushed you inside. She closed the door and locked it. “Come on. Claim your price.” She said looking at the ground. “What? Right here? You’re crazy.” You said. “Do it idiot! Lets get this over with.” She said while pulling your pants down. She jumped at you and started kissing you. Both your tounges started licking each other. “You are a complete idiot.” She said while kissing you. “Im not the idiot who lost the first place at the last second.” You replied. She started to rub your cock with one hand. She climbed on you, moved her swimsuit with her hand and started to rub her ass on your tip. She let out a soft moan. “Come on.” She said. She started to press her butt against your dick while kissing you. It started to go slowly inside of her as she softly grunts. Suddenly she went forcefully all in with a moan. She started moving up and down while placing your hands on her cheeks. “Am I going to do everything idiot? Come on” she said grunting. You spread her ass and started thrusting inside her. You felt the soft wet skin of her butt with your hands. Her wet hair on your shoulder and her warm breath on your chest. She went in and kissed you again. You both end up having anal sex on a changing room. You were driving back home. She was sitting beside you on the passenger seat looking at her second place medal silently. “You lost on purpose, didn’t you?” You asked, “What? Absolutely not.” She replied grumpy. “There is no way you lost. You were meters ahead of all of them. And in the last lap you slowed down. AND you stopped right before the finish line just to make sure the other girl reached it first, didn’t you?” “Shut up! I didn’t do that! I told you she cheated!” She said looking away. You stayed there silent. “Why would I prefer having anal with an idiot like you over a first place medal…” she said quietly. “And ice cream!” She said loudly. “You’re an idiot for thinking that!” She added. Well, it seems she indeed actually preferred making you happy rather than winning a medal for herself. She really loves you that much to the point she would lose on purpose even if she doesn’t wants to admit it. The car stopped, and you turned the engine off. She looked up. It wasn’t home, you parked in front of the ice cream shop. She looked at you happily. “Come on you worm, lets get your ice cream.” You both opened the doors and she sprinted out of the car to the shop entrance. You walked behind her being proud of her. She was about to enter the store but turned around. She sprinted back to you and grabbed your hand. “Come on!” She said happily and started to drag you to the ice cream shop while giggling.
