Sharing My Room With Sis 6: Loosing a Bet

“So what do you want to do tonight?” My sister Abby was lying on my bed as I came out of the bathroom. It was Friday, and we’d just gotten home from school and had the house to ourselves.

“I have a few ideas,” I said. I walked over next to her, standing next to the bed.

“I think I know what you have in mind.” She leaned her head towards me and softly kissed my dick through my pants. “Last night you didn’t really get a chance to savor it.”

Abby and I had been sharing my room since hers was flooded in a storm, and had spent over a week being more than a simple brother and sister. The night before, I’d come into my room to find her already deep asleep, and too horny for her to be satisfied with porn, I had started touching her. As I grew bolder, I had ended up rubbing my dick against her lips until they had wrapped around my head. After only a moment I’d pulled out and cum. Only after I was done did I find out she had been awake.

I sat on the bed next to her. Our heads leaned together and we began kissing. After our lips separated, she pulled away. “I just remembered, I have a science project I need to work on this weekend. I’d better start on it tonight.” She told me what it was. I’d had the same teacher the year before and had done the same project.

“I remember that one. Isn’t it a group project, though?”

“Yes, but the other members of my group didn’t volunteer to do much. It’s better if I do it myself.”

“Abby, don’t be such a pushover,” I told her. Abby had always been shy, and was afraid of confrontation. “It’s not cool that your group saddled you with all the work. Why’d you let them do that?”

“I don’t know, I didn’t want to be the bitch.”

“There’s a difference between being a bitch and standing up for yourself.”

“Sorry.”

“See, there, you’re doing it again,” I teased her. “Stop it! You can’t be so afraid of making other people uncomfortable.”

She rolled her eyes. “Fine, I’ll try next time.”

She worked on the project a while, then we headed out to grab some burgers for dinner. We got our food and sat down at a table. Abby opened hers, sighed a bit and pushed it to the side.

“They get your order wrong?” She nodded. “Take it back up there and get them to make you a new one.”

“That’s alright, I’m not that hungry.”

“This is exactly what I’m talking about. A little confrontation won’t hurt anything. They get this a dozen times a day; they don’t care. We paid for it, they should get it right.” She still hesitated. I rolled my eyes, then took the burger back myself. I came a couple of minutes later with a new one. “See.”

“Fine.” She was obviously annoyed at my pushing her. I decided to drop it for now.

We went home and Abby declared she was taking her dog for a walk. Feeling anxious that she was mad at me, I grabbed my dog and went with her. We walked down to the park together as we’d done for years. When we got there we let the dogs off their leashes and Abby threw a ball for her dog Angie, a blue healer. My dog Willow, a German Shepherd, ran and beat her to it.

“Your dog’s being a jerk,” she said to me. She was clearly still annoyed.

“My dog’s fine. I think Angie’s just being a push-over.” I’d reverted to my older, more antagonistic big brother self. My comment clearly didn’t go over well.

“No she’s not! I bet she beats Willow this time.”

“You’re on.” Buster brought the ball back to me, and I tossed it back to Abby. As she picked it up, I stepped closer to Angie. When Abby threw the ball, I grabbed Angie’s tail a moment, giving Willow a head start. “See. Angie is a push-over.”

“Cheater. You’re afraid of a fair race.”

Willow had always been the faster dog. There wasn’t really any question who would win, but now Abby had committed to backing up Angie’s honor. I decided to exploit this. “Tough talk. What are we betting?”

“Loser has to be the winner’s slave for a day.”

“Alright.” It was a bet we’d done once a couple of years ago. I had won, and had made Abby follow me around taking small orders and then clean up my room before I lost interest and did something else. This time, however, the old kid game had an entirely new subtext.

Ideas were already coursing through my head for what I’d do with her. Mom had 12-hour shifts tomorrow and Sunday both, giving us free reign of the house. I could have her bathe me and get dressed, or have her pose naked for some pictures. I didn’t want to push her too far out of her comfort zone, but a little might help make her a little more assertive. Mostly, though, I wanted to get my dick in her mouth again. I wondered how many blowjobs we could get into one day.

I got the ball from Willow and handed it back to her. She paused a moment. “Are you sure you want to go through with this?” she asked.

I wasn’t about to let her back out now. “I do if you do,” I said, somewhere between confident and condescending.

“Alright,” she said. She turned to her left and hurled the ball a different direction than before, and the dogs went rushing after it. Even as I wondered why she’d thrown it that way, I saw the other dog down there.

Willow may have been faster, but Angie was the better trained. As soon as Willow saw the other dog, she rushed towards it. Abby had spent more time teaching Angie to follow commands and avoid distractions. Willow had just started sniffing the other dog when Angie grabbed the ball.

Abby had flat-out outsmarted me. Somewhat flabbergasted, I went down and collected Willow. On the way home, Abby smiled, whistled, and was almost skipping, all trace of her earlier grumpiness gone.

At home we headed to my room to get ready for bed. Abby hit the bathroom first and came out already dressed in her pajamas; a white tank top and very short shorts. She walked up to me and slowly wrapped her arms around me. Her mouth approached me as if to kiss, then she stopped abruptly. “You’d better get a good night sleep tonight, brother. Tomorrow’s going to be a long day.” She released and slid past me to the bed.
