SibFn/Leave her clothes on

From Create Your Own Story

You decide to leave her be and leave the room. You try to sleep, but can't get the feeling of her flesh to leave your hands. The more you try to think about something else the greater the feeling becomes. It also leads to a hard on and you have to take care of business. As you stroke your dick, you try to come up with some fantasy, but your sister appears to override everything. You decide to give up on the idea of fighting it and cum harder than you ever have while thinking of your dear sister.

The next day she thanks you for a great birthday. You continue to drink with her, but she never gets that drunk again. You continue to fantasize about her for years, even after getting married, but never act on your fantasy. Perhaps, if you had done something that night, the torment of her on your mind might be gone.
