We always been normal brother sister. Yea of course I noticed she's hot but it never meant anything to me. And honestly it still doesn't. At the end of the day she's my sister and we are still close and normal. But im helping her move. Everyone is helping. Its a full family help. But there is one last load that will fit in my truck. The two of us go back and load it up. She's been there for years so we do some good bye cheers and shots. We leave and go directly to the liquor store. On the way to my house we are drinking and listening to music. Very drunk and yes driving. Stop at liquor store before my house. Take more shots and more music. Then out of no where she says. Damn your so lucky your my brother cuz im ready. And she's giving me that look. I heard but was still confused. There's no way I heard what I heard. And she's literally biting her lip. At that moment we weren't related. I told her that if she is saying what I think she saying I will find somewhere and pull over. She just looked at me and shrugged her shoulders. I found a spot and was still unsure and hesitant. Made sure we were on the same page because that's a wild thing to misunderstand. But it was mutual. And I went over to the passenger and pulled her legs out and sweats down and I still waited. Then my shit was ready and once I put it in I didn't stop. I finished in her. After that we sat in the car like what the fuck just happened. A few minutes after that I was there again. After we drove to my house and unloaded her stuff in my garage. Went to bed and woke up like nothing ever happened. But since we have done it twice more. And nothing is weird between us. She said it's the best affair coz no one will suspect it. We can hang out with no one thinking anything
