“Shit, mom’s home. I promise I’ll return the favor later. Just be patient please.”
“Ok sis, but you owe me.”
We both sprinted into my room. Lisa was first to emerge after putting her clothes on. I had to wait for my erection to go down. When I finally came out, Mom was putting some take out on the table and Lisa was getting plates and silverware.
“So, what did you guys do today?” My mother asked innocently.
Lisa responded, “Johnny gave me a hand.” Brief pause. “…with the laundry.”
“Oh, that was nice of him.”
All that night I tried to think of a way that I could get Lisa away long enough to get my half of the bargain. Meanwhile, Lisa started a game of teasing me. For instance, when Mom got up to get a little more food, Lisa lifted her shirt to show me that she was not wearing a bra. The whole motion took only a few seconds, but by the time that mom got back to the table I was rock hard and trying to cover it with my napkin. Then later, when I leaned down to pick up my napkin I looked over and noticed she had changed into a mini skirt. I also could tell that she had not put any panties on. She was spreading her legs slightly yet intentionally.
“Do you want some more?” Lisa asked with a smirk.
“Well, I’m actually waiting for dessert. I believe I deserve some.”
“Let me get you some.” My mother interjected.
My sister chuckled at the missed innuendo, but I knew how close it was to the truth.
Just as dinner was ending, Lisa received a call on her cell phone. She was going to have to leave the next morning. This meant that I was on a limited schedule. I was going to have to think fast.
“Hey Lisa, you want me to go with you to get some snacks for the road?”
“Yes, maybe I could even get you something for helping me out today.”
“Finally.”
Although mom was oblivious to the whole thing, I was surprised that in the back of her mind she didn’t think that something was funny.
Lisa grabbed her keys and we both got into the car. We didn’t really say much on the way to the store, nor while we were in the store for that matter. She actually did need to get snacks.
“I know that this isn’t fair, but we kinda need to make this quick.”
“Ok.” I responded.
“I promise it will be good though.”
As we were driving down the interstate my sister looked over at me and asked me to take the wheel. While I steered the car, Lisa pulled her shirt over her head freeing her big beautiful tits. She grabbed my hand off the wheel and put in on her right tit.
“Is this illegal?”
“Driving while doing it? Or doing it with my brother?”
“Hmm, good point.”
“Ya know, there is something about doing this with you that is so much more exciting. Maybe it’s the taboo of family. This is making me wish I had more brothers.” She chuckled.
“Yeah. I hear what you’re saying.”
“I want to tell you a secret, but you can’t let mom know that I told you.”
“Oh, this sounds good, what is it?”
“Well, back when I was living at the house, mom and I had this little routine going.”
“Really? A routine?”
“Well, it wasn’t very often, but when I had trouble sleeping, I would tell mom and she would come into my room.”
