Good son: lick her ass
From Create Your Own Story
You can´t hold back any more. You have to taste her. You press your tongue about 1 inch under Siri´s asshole and slowly lick through her crack and over her hole.
"What are you..." Siri can´t finish the sentence, because you already trailed you tongue back down, stopping on top of her asshole and slightly press against it. As soon as you enter her entrance a little bit your sister´s greedy asshole pulls your tongue deeper inside of her. You start to slide in and out of her.
You run your tongue up and down, in and out, occasionally stopping to draw circles around her hole. Siri squirms slightly as your tongue hits the right spots.
The scent of your sister is too powerful, too intoxicating, too heavenly. You keep going to town, rubbing your face between her asscheeks as you lick, slurp and suck at the hole pressed against your mouth. Up and down your tongue goes, in and out, teasing her and pressing hard against her aching asshole.
All of a sudden Siri´s body starts to jerk heavily. She cries out your name as she feels her first assgasm in her life. You step back from her a little bit and let your exhausted sister catch her breath again.
"I don´t think I want to go to the pool anymore..." your sister says. "Let me just take a shower real quick ok? I am all sweaty after... you know... what we just did..."
She leaves the room to go to the bathroom.
