Start off gently

You placed your hands on her thighs and leaned forward. The old woman bit her lip in anticipation, then finally you stuck out your tongue right inside her lips. She almost came right then and tried to lock your head in place, but your dad grabbed that hand of hers over her head. She moaned and panted happily at your ministrations, but you were just getting started.

You lightly nipped her clit then dove in and devoured her delicious mature pussy. You pleasured her with your tongue in every way you knew how, and her lips moistened until her lady cum dripped steadily into your waiting mouth.

The organist closed her eyes and went limp, clearly enjoying herself now. You motioned to your dad to let her down and he gently sat her down in a chair. She gripped the seat until her knuckles turned white and you continued gobbling up her womanhood. She tried to squeeze your head to hold you in place, but she had very little strength and it did nothing.

You pulled out and she whimpered like a puppy, but then you replaced your tongue with your fingers and tickled her from the inside. She laughed with sheer joy and wiggled in her seat then finally came all over the chair and your arm. She quivered like she was made of gelatin and her fingers joined yours inside her pussy for just a moment until she came down. The old woman sighed with satisfaction and stroked your hair lovingly.

"Thank you, good boy," she said.

"Are you ok?" you asked.

"Now that I can think again," she said and looked around at all of the sleeping men in the loft, "Oh my, did I fuck the snot out of all these boys myself? I guess this old girl can still play with the kids."

"I guess you can," you said, "But we really need to be going."

"Aw, but you didn't get to cum yet," she said and flipped her silver hair off to the side so it glamorously covered one of her eyes, "Come here and give granny some sugar."
