Good son: start fingering her pussy
From Create Your Own Story
You can´t hold back any more. You have to feel her insides. You place one finger about 1 inch under Siri´s pussy and slowly trace it upwards over her slit.
"What are you..." Siri can´t finish the sentence, because you already traced your finger back down, stopping on top of her vagina and slightly spread her lips apart. You take your other hand and press against her slit with one finger. As soon as you enter her hole a little bit your sister´s greedy pussy pulls your finger deeper inside of her. You start to slide in and out of her.
Seeing how greedily she pulls at your finger you add another one. In and out you fingerfuck her love tunnel, occasionally stopping to pull your fingers apart to stretch her hole out more. Siri squirms slightly as you hit the right spots.
The scent of your sister is too powerful, too intoxicating, too heavenly. You keep going to town, fucking her insides with your fingers as her tight walls clamp around you. Your sister starts moving her body in rhythm with your fingering.
All of a sudden Siri´s body starts to jerk heavily. She cries out your name as she cums hard. You fingerfuck her until her orgasm subsides before 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.
