Brother finds out sisters secret. And brother realizes his love for his sister

“Jack, hurry up and come down!” , my younger sister Lisa called from downstairs. Our parents were away for vacation for 1 month and it has been only 3 days since they left. Oh and I forgot to introduce myself.

My name is Jack. I am 6’11 a little bit tall for my age because that’s what my sister always says. Well I am 19 and I have a sister who turned 18 and her name is Lisa. Even though we are siblings we look no thing like each other. I have dark brown hair and green eyes. But Lisa has black hair and light blue eyes. I knew why we looked nothing like each other and that was because Lisa was adapted.

Me and my sister never really got along. I don’t know what was the reason she hated me for but I didn’t really hate her as much as she hated me. Growing up I always had so many girlfriends and Lisa had a lot of boyfriends too. I guess guys dated her probably because of her looks and body. Well I gotta admit she is kinda sexy. She has c-cup breast and a nice tight ass. I knew that was the reason she is popular with guys but her personality was crap.

The day mom and dad left they told me to take care of the house and my sis. But mostly she took care of the house, chores and…me. She made breakfast for me early in the morning which was the first time she showed me kindness. But the moment I started eating she started bragging about me being a lazy bum and how she was so more adult-like than me. That made me cringe for a moment because every time she is sad she would go to mom and start crying like a little baby and would even beg mom to sleep with her.

After breakfast on the 3rd day I got a message from my girlfriend saying she want to come over at my house. Of course I agreed because I was hungry for sex in the last couple of weeks and plus my parents weren’t home it was just me and Lisa. So I told her to come in a couple of hours. I went upstairs to Lisa’s room and said, “Hey Lisa, Maddie is coming over right now so don’t interrupt us please.” As I was about to head back I heard Lisa saying, “Jeez all of your girlfriends and total slut…there are probably better girls out there for you.” Of course I had to reply, ” Ok and you got a problem with that?” I asked in anger but I didn’t realize it and that’s when I realized that she had just broken up with her boyfriend because he tried to force her to have sex with him and she was upset all day over that. Before I could apologize she replied back with a sad look on her face, “Yes Jack, I do have a problem with that.”

My heart started pounding as she said that. Was she jealous? I thought. “W-what?” I asked nervously. “What? I do have a problem because I always hear you and your girlfriend fucking and it’s annoying because I don’t get any sleep because of you guys.” Then I finally calmed Down. “It’s not like we will…” Before I could finish off I heard the door bell ringing. “Coming.” I called out. When I opened the door it was a mail delivered so I was kinda disappointed. But right then I got a text from Maddie saying she won’t come because her mom and dad were not in the house. I was so disappointed but I went to my room hopped on my bed and took out my cock and started stroking it gently.

Then I heard soft moans from the other room which was probably Lisa. I quite didn’t make out what she was saying but all I heard was her saying, “Aw fuck your little sis….don’t stop….ah…ah ah”. I almost froze at the words she said. Is she thinking of me? I quietly tip toed to her bed room door and opened it.When I opened the door there was my sister lying there naked on her bed. We both looked at each other for 5 seconds then we both looked away and I quickly said, “I am sorry” as she covered herself with her blanket. I walked out as quick as possible, surprised and nerves at the same time.
