Script by u/Haisebtw
Summary: You had been messing with your little sister for a while, but you knew you couldn't keep this going forever. After all, you want to get married and start a family of your own.
Now you're engaged, but you have a "little" problem. You are only interested in your partner because she looks just like your little sister.
You may be able to lie to yourself about it, but little sis knows better and she is going to try her best to end this facade and future disaster.
What do you mean you don't know how to make yourself cum yet? We ought to change that!
Thank you to /u/lvlxb for this delightful script, and thank you to /u/puzzleheaded-numbnut for the lovely request!
First audio so I apologize for the audio, the static, or being a bit of an amateur to this. I hope to improve and will gladly take any criticism that anyone possibly has. Otherwise, have a great time!
