After that weekend, Corey had asked out Addie’s best friend, Tina. She was a nice girl with long brown hair and a pretty smile. They’d gone to the movies and all the usual high school dating stuff. Corey thought it was going pretty well, and Tina really did seem to like him. While with her, in the back of his mind, he kept thinking about his sister. Tina would lean in for a kiss and he would feel guilty for responding. The longer they dated, the more Tina wanted to make out and get even more physical. Despite really liking her, he didn’t know how much longer he could continue while feeling like he was cheating on Addie.
Addie had told him it was ok, encouraged him to date her friend, and mentioned that he should be the one to take her virginity, but he didn’t know if he could do it. What would happen if Addie got jealous and it ruined her friendship with Tina? Or worse, what if it ruined the relationship he had with his sister? That was something he didn’t want to risk, so he just kept avoiding escalating things further.
Over the past several weeks, the two siblings would sneak around together whenever they had a chance. They would make out after their parents went to bed, but Addie would get too loud when she was getting pleasured. One night, while they tried having sex late at night, Corey had to cover his sister’s face with a pillow to keep from waking their parents. He joked that maybe she needed a ball gag to keep from screaming so much. They were desperate for some unescorted time together and they were about to get it.
Corey was in his room watching a YouTube video when his sister entered excitedly.
“Did you hear Aunt Judy’s going into labor?” Addie said, bouncing up and down.
“Yeah, so?” Corey replied, having not seen his aunt and uncle in months. They lived a few towns over and didn’t visit often.
“So? Mom and Dad are leaving tonight to be there. They’re staying there till the kid is born.”
“Again, so what?” he replied, not understanding her excitement. It was just a baby, not a big deal.
“Hey genius,” she said, turning off his monitor, “we’ll ... be ... alone,” she emphasized, cluing him in.
“Oh, OH, SHIT!” he said as he finally got what she was saying. “What do you want to do?”
“I’m sure we’ll think of something,” she said with a wink, “but first, wanna see who’ll be in charge while they’re gone?”
“Like the last couple of times?”
“Exactly. I like telling you what to do,” Addie said, thinking back to the last time she was in charge.
“Maybe I’ll win this time. Then you would be afraid. How do you want to decide? I don’t feel like Mario Kart.”
“Afraid you’ll lose again? Fine, let’s just do something simple. Rock, paper, scissors: best two out of three, deal?” said Addie confidently.
“Deal. On the count of three ... One ... Two ... Three!”
Addie chose rock while Corey chose paper.
“That’s one for me. Again, One ... Two ... Three!”
This time, Addie went rock while Corey chose scissors.
“Tied up, final round, One ... Two ... Three!”
Addie had scissors while Corey went rock.
“I win!” he said triumphantly. “Oh, I’m going to have so much fun!”
“Yeah, yeah. Well, don’t go too crazy with...” Addie heard someone coming up the stairs, “shhhh... So yeah, how are things going with Tina?” she said, trying to cover.
Their Dad entered the room, seeing them together. “Alright guys, we’re about to leave. Try not to burn down the house and no parties. There’s money on the counter for food and be careful if you drive anywhere. We shouldn’t be gone more than a day or two.”
“We’ll try Dad. Safe travels and give our love to everyone,” Addie said, hiding her excitement.
“Ok. See you both soon. Bye,” he said as he went down the stairs and out the door. They watched the car pull away and it was soon out of sight. The siblings were now free for the next night or two.
“Ok, Corey. What’s the first thing you want me to do?” Addie asked, readying for his revenge.
“First, let’s order some food. Pizza, maybe?”
“Yeah, that sounds good,” she said suspiciously.
“I’ll order and you get dressed. Pepperoni and bacon good?”
“Yeah, sounds good. What do you mean dressed?” Addie asked, looking at her cute outfit.
“Of course, I want you to change into a dress. I think you know which one.”
Addie quickly understood which dress he meant and went to her room to find the one she made him wear when he was her servant. Corey is 6” taller, so it wasn’t as short on her as it was on him. But it still looked good. The pizza arrived shortly and they sat down to eat. When they were full, Corey had her clean up while he watched her work.
“Ok, time for you to clean my room,” Corey said, leading her to the stairs. He walked behind her and could just see the edges of her thighs looking up her dress but couldn’t see if she was wearing panties or not. As they reached his room, Addie looked around wondering what he wanted cleaned. He always kept his space spotless, with rarely a sock out of place.
“What do you want me to clean, Corey?”
“I want you to clean under my bed. Get down on your hands and knees,” he said with a grin.
“Yes, sir,” she replied and made a show of bending over, showing him she wasn’t wearing anything under the dress. Addie got down on her hands and knees as instructed and feigned looking for things under the bed. She heard rustling behind her, and then her skirt flipped up. In a flash, she felt him slip into her wet depths as she moaned out in pleasure.
“What are you doing, brother?” she said jokingly, as she enjoyed him using her pussy again.
“I’m just playing with my little sister, since I’m in charge this time,” he said, as he thrusted into her.
This was the first time the two of them had done it in this position and they both were taken by the change. Addie could feel his cock slamming deeper into her and hitting different pleasure points in her body. Corey enjoyed more movement and getting to grab her by the hips. He looked down as he pounded into his sister and saw her tight little pink anus. It looked so small and delicate, he felt drawn to touch it. He took one of his hands and slid it between Addie’s legs, rubbing her clit and getting his fingers wet. She nearly came, as the feeling of being fucked and fingered at the same time was so intense.
She was disappointed when he withdrew his fingers, but felt a strange sensation a short time later. It was light pressure against her backdoor. Corey had started simply circling her hole, but then wanted to see what it felt like to penetrate it. He put a little more pressure on it and his finger slipped in, but only to the first knuckle.
“What are you doing back there?” Addie asked, unsure of how it felt.
“Just seeing what your sexy little body can do. Don’t worry,” he said, before pushing in farther to the second knuckle. “How does that feel?”
“So weird, but also good in a way. Everything in my body is so sensitive right now from you fucking me, so don’t stop.”
He pushed the rest of his finger in, feeling the heat and tightness of her ass. Addie was groaning and starting to shake. He knew neither of them could last much longer. Corey started fucking her ass with his finger, while his cock thrust into her pussy.
“I’m about there!” Addie said, loudly.
“Me too. Where do you want it?”
“In me! I love feeling you cum in me.”
A few seconds later, Corey exploded in her tight passage, flooding it with his slippery sperm. The feeling of his cock coating her inner walls brought Addie to a boisterous orgasm. The two slowed down and Corey pulled his finger from her ass, then let his cock slide out of her. She stayed on her hands and knees. Her freshly fucked pussy was leaking their cum onto the floor, as they both recovered from their first fuck of the evening.
Addie eventually sat up and moved beside her brother, as he put his arm around her shoulder. They sat together, enjoying the afterglow of their sexual coupling, Corey leaned over and kissed his sister lightly on the lips and she kissed him back in return. It was a simple gesture of love between a brother and a sister.
“So, what’s next,” Addie asked, “since I’m in your service today?”
“First, we take a quick breather, and then I think we’ll have some dessert. Is there still ice cream in the freezer?”
“I think so, why?” Addie asked dubiously.
“I want something sweet to refill those calories we just burned,” Corey said, giving his sister a little friendly shake, “Not everything is a torment.”
They relaxed for another ten minutes, letting their bodies recover before finally getting up. They both stretched as they stood up off the floor. Corey noticed a visible puddle of cum where Addie had been sitting. He had her clean it up while suggesting she try to keep from leaving a trail around the house. Addie understood and went to the washroom to remove some of the excess leakage. As she returned, Corey had her next task.
“Ok, servant. I want you to go to the kitchen and bring back ice cream, some spoons, chocolate sauce, and whipped cream.”
“Yes sir,” she said, walking towards the door. Corey stopped her.
“One more thing. For the rest of the night, I want to see your sexy little body.”
Addie grinned and pulled the dress over her head and threw it on the ground. She did a little spin for his inspection. After presenting herself from all angles, she headed down to get the supplies. Corey’s cock was already starting to come back to life, after looking at his sister’s firm little titties, sweet ass, and her tight slit.
After a short time, Addie returned carrying a tray with all the requested items and put them on Corey’s desk. She handed him a spoon, a bowl, and then the container of ice cream.
“Addie, I didn’t ask for bowls,” he said slyly.
“Oh? Then how are we going to eat it? Right out of the container?”
“I had a different way in mind. Lie down.”
Addie was unsure what Corey had in mind, but followed her brother’s instructions. He picked up the container of ice cream, took the spoon, and scooped out a portion. Leaning over his sister’s body, he dropped the scoop between her breasts. Addie yelped as the cold shocked her skin. Corey then used the chocolate sauce and drizzled it over the ice cream and his sister’s tits. Finally, he finished it off with a spray of whipped cream.
“Voila!” he exclaimed, “An Addie sundae!”
“It’s very cold,” she said, taking a spoonful off her chest.
“Then we should eat it quickly,” he said. As he licked some of the ice cream and chocolate sauce off her chest, he passed over one of her rock-hard nipples.
“That feels nice, but it’s tough to do the same to you right now,” Addie said, taking another spoonful.
“Then I guess I should eat you quickly, so you can have some fun too,” Corey said, before diving face first into the messy food on her chest. Addie giggled, feeling his tongue lick all over her chest, lapping up the melting ice cream and chocolate. She looked down at his face, covered in a sticky white and brown mess, and laughed before pulling him in for a sloppy kiss.
Corey’s upper body was now covered in the sticky slop, too, but he moved his head back down to enjoy running his tongue over his sister’s chest. He paid close attention to her breasts and nipples, making sure to clean them extra well before confirming it was all gone. The two kissed again, their bodies sticky from all the sugary substances.
It was now Addie’s turn, having her brother lay down on the floor and dropping a dollop of ice cream on his chest. She also added chocolate and whipped cream, while putting an extra dollop of whipped cream on each of his nipples. Her head dropped down as she started eating it off his body. She also took special care to clean the extra off his nipples. It was a strange sensation for Corey, but he enjoyed the attention. Soon, he was sticky but cleaner.
“There isn’t much ice cream left, but plenty of chocolate and whipped cream,” Corey said. “Lay down and spread your legs, I want to eat something else.”
