Corey hung out in his room the next day, wondering when Tina would call his sister, Addie. He was curious how things would go down and what Tina would say or suggest. He ultimately decided against going to Addie’s room to wait for the call, fearing that his sister might let it slip that he was there, listening. That might open up a massive can of worms that he hoped this little plan might alleviate.
He felt helpless as he waited in his room. This was the part he feared the most since he couldn’t do anything if things should go south. He did want to see the look on his sister’s face when what he’d said the previous night was confirmed. Tina didn’t want to lose her virginity before Addie did. It was funny to Corey, though, since he’d already taken both of their cherries earlier.
He watched the clock, impatiently waiting for some sign of a conversation happening. He tried to distract himself with video games, starting one up on his computer. It was a single-player story game that he had been playing on and off for a while. He found himself unable to focus on the story, though. It took almost half an hour of playing to realize he had no idea where he was in the game. He exited without saving and turned around to see Addie standing behind him.
“Well? What’d she say?” Corey asked, somewhat nervously.
“I can’t believe you were telling the truth,” Addie said as she sat on her brother’s bed. “She didn’t come right out and say it, but I could read between the lines.”
“What exactly did she say?”
“She asked what I meant when I said I wished you weren’t my brother. I said she was lucky she was dating such a nice guy, and I would be lucky to find someone half as good.”
Corey couldn’t help but feel both happy and sad at that statement. Good in that his sister truly loved him, but sad that she felt she wouldn’t find someone else herself. Despite all that had happened and their disagreements, he only wanted the best for his little sister. He loved her more than a brother should, which made him more protective of her.
“Was that it?” asked Corey as he studied the emotions on his sister’s face.
“No, she asked if I could help her with something. She didn’t want us to fight anymore and hoped this would solve our problems. It ... it sounded just like you said. She asked when the next time our parents would be out of town. I told her next Thursday.”
“Now that you know it was true, what do you think? Honestly.”
“Honestly, I don’t know. While it would be nice to have someone to talk to about what we’ve been doing, that isn’t really what this is. I have to pretend it is our first time together, which isn’t true, and then you’ll have Tina while I get left in the dust.”
“Well, who knows what can happen afterward? It’s a start, but it doesn’t mean we stop doing what we’ve been doing. Ok?”
“Ok, I guess. The other thing. Do I have to do stuff with her?” she asked, her face blushing a slight red. Corey wasn’t too sure how to respond.
“Well,” he paused, “you can if you want to. That’s between the two of you, I suppose. Do you want to?”
Of course, Corey would love to watch his two favorite girls go at it in front of him. That’s the dream of most men, especially when they are as sexy as Addie and Tina. He only thought this was a pipe dream, but maybe something could happen. Addie just paused and looked at her feet, uncertain about her answer.
“I don’t know, this whole thing seems weird. You’re my brother, and she’s my best friend, but I feel like I owe you both for what I did.”
“You don’t have to do anything, Addie. There’s no pressure.”
“Oh, I know. That’s why I told Tina I would help her next Thursday,” Addie said with a big grin. Corey felt relief. Addie continued, “As for the rest, I don’t know. We’ll see how I feel that night. No promises.”
“Addie, I could kiss you,” an excited Corey said as he jumped out of his chair.
“Maybe tonight,” Addie whispered, “Mom and Dad are lurking about. You must surely be excited to finally sleep with your girlfriend, and I want some of that action.”
“Addie, that was the perfect way to put that,” Corey said as he laughed. Addie realized what he meant and joined him.
As the day approached, Corey made separate plans with each girl. The idea was to keep each side from knowing how much the other knew. It seemed overly complicated, and Corey had difficulty balancing the two, but in his mind, it needed to be done. Everyone was excited, though, as it got closer. Tina was looking forward to being able to share the joy of sex with her best friend and help her through her first time.
Addie felt the same and was excited to have a chance to be open about her relationship with her brother, at least in a limited capacity. She never thought she’d be able to do it at all, so she’d take it. Addie also hoped to repair the damage she thought she did to Corey and Tina’s relationship. She’d regretted it ever since it happened and hoped this would fully mend that fence.
Corey himself was nervous but excited. If everything went as he planned, all three of them would be in a better place. He and Tina wouldn’t have to hide their intimate relations from Addie, and he and his sister might be able to be more open with Tina. Since he was in the middle, he knew both girls were counting down the days, and so was he.
Tina had even convinced her parents to let her sleep over on the condition that she only slept in Addie’s room. Granted, they were also told that Addie and Corey’s parents would still be home, according to Addie, so they believed it. The three of them would have all night to do whatever they wanted. This was the sort of thing Corey hoped could happen again, but with both girls fully aware of everything.
When the day arrived, both Corey and Addie had to look calm, like it was just another day. It was 2:00 in the afternoon when their parents were ready to leave for the night. They both said goodbyes and watched the car drive away. As soon as it was out of sight, Corey had his phone out to let Tina know the coast was clear. Tina arrived fifteen minutes later wearing jean shorts and a light blue blouse. She walked in and kissed Corey hello, then hugged Addie. All three of them knew that tonight would change things between them. They just all hoped it would be for the best.
“So, what’s the plan?” Tina asked, eyeing up her sexy boyfriend.
“Well, why don’t we play some games or something?” Corey suggested getting the plan moving forward.
“Ok, like what? It better not be Mario Kart. You both know I suck at that,” Tina said, remembering the last time they all played together.
“Uh, do either of you know how to play poker?” Corey asked as he moved to a cupboard with a bunch of dusty board games.
Both girls replied no, which ruined his hope for strip poker. He looked through their different games, most of which they hadn’t played in years. He was looking for a game that he could easily rig to give Addie an advantage. Monopoly was an option. Hiding money under the board or swiping from the bank was possible, but the game took too long. It was a no to Scrabble and Boggle since no one wanted to do word games. A few two-player games, like Battleship, didn’t work.
On the bottom of the stack, he found Clue, the murder mystery game. That could work, he thought to himself. Both girls were up for it, as it was something that neither had played in such a long time. Corey set up the board on the kitchen table while the girls got snacks and drinks. When they were all ready, Corey separated the crime cards into the envelope in the center of the board and dealt out the remaining cards.
“Why don’t we make this more interesting? A wager, perhaps?” Corey suggested as he secretly marked off his cards on the notepads.
“And what would be the bet?” Tina asked, although she knew the answer.
“How about the winner gets to tell the losers what to do for two hours,” Addie suggested.
Everyone agreed to those terms, and the game began. Corey had a plan, though. Whenever Addie would take her turn and guess if he had a card she was looking for, he’d show her a couple of others, too. It gave her extra information faster than anyone else. Corey hoped this would give her the win.
The game moved along quickly, with each of them taking turns and collecting clues. Addie quickly figured out what Corey’s plan was after her first turn, where she looked at one of his cards, and he showed her two instead. She focused on quickly knocking out all his cards before going after the holes in her list, which belonged to Tina.
Tina, for her part, was trying to play the game properly. Occasionally, Corey would slip her some information just to keep the ruse going, but not enough for her to advance quickly. Corey had to sit back and wait to see how it played out. Realistically, it didn’t really matter since both girls aimed for the same thing, but this time, Corey trusted his sister more. She was more experienced in these types of things, plus making bets was something they’d just done their whole lives.
“I’d like to solve,” Addie said on her next turn. “Mrs. Peacock in the library with the candlestick!”
“No way you’ve got it so fast!” Corey said as he played along. Addie opened the little envelope and pulled out the cards.
“I win! Yay!” she cheered and jumped out of her chair.
“Damn it!” Tina said, frustrated with the outcome. She turned to Corey with a look of ‘What do we do now?’’ Corey just nodded and gestured for her to stay calm.
“Oh, this will be fun. I have two slaves now!” Addie said maniacally as she rubbed her hands together. “Tina, we’re going to have fun tonight. Corey, well bro, you should know what to do.”
This was the one thing Corey had hoped Addie wouldn’t do: embarrass him in front of his girlfriend. He looked at her, his eyes pleading for mercy, but she just shook her head and nodded towards the stairs. Tina looked confused, clearly unaware of the now long-standing meta-game the brother and sister played together. Corey lowered his head in defeat and headed up to Addie’s room.
Addie put her arm around her friend, “Tina, this will be funny. Trust me.”
Tina wasn’t sure what was happening but was somewhat used to the weird games these two siblings played. It made her wish she’d had a brother or sister to have these kinds of inside jokes. They both waited a few minutes and heard the door open and footsteps down the stairs. Tina’s mouth dropped, and she couldn’t help but laugh at seeing her boyfriend in a little flowery dress.
“Har—dee har har!” said Corey with a look of humiliation on his face.
“Doesn’t he look cute, Tina?” Addie said with a laugh.
Barely able to breathe, Tina can only nod yes. She knew they got weird with their wagers, but this was something else. Corey stood over her and tried to help her to her feet, but all Tina wanted to do was try to look up his skirt.
“What the hell are you doing?” Corey asked as he tried to cover himself.
“I just wanted to see what was under there. Did you still have boxers on, or did you go full into character?”
“Into what?” Corey asked.
“Are you wearing her panties too?” Tina laughed as she once again tried to pull up his skirt. She was actually enjoying the role reversal. She almost forgot why they were there.
