[Story]
I have a sister who's two years younger than me. She's the plain, bookish type, so I never paid her much mind. But one day, everything changed.

That was the day she got a cell phone. After that she got into makeup, started to dress flashy and dye her hair, and got pretty cute... she was like a totally different person.

She also started using lots of dating apps and playing around with men. She's become a real woman, and lately I've found myself sort of fascinated...

One day I walked into the living room, and there she was asleep on the couch. Her sexy body was utterly defenseless. So, I had my fun with her tits, ass, and pussy, and then I kept going... I took off her panties and jacked off while looking at her bare pussy. I ended up blowing a huge load all over her, too.

Later that night, I opened my eyes, and my sister was on top of me! She said she was getting revenge for earlier by sucking my dick.

"Wanting to fuck your sister is pretty gross lol" she said. Well, I took that as a challenge and started licking her between the legs. That'll show her! I still came first, though.

"You must be frustrated that I beat you." she sneered, presenting her well-used pussy to me.
And things only got more intense from there... I thought it would never end!
