Tilly was a vivacious 10 year old. She was beautiful, with soft blue eyes and soft red hair that framed her sweet face like a halo. and she was always happy and playful and a fast learner. And she was friendly. Sometimes too friendly. Plenty of times when Tilly would snuggle with him on the easy chair dressed only in her pajamas, and Thomas would have a natural reaction. His cock would harden under her, and Tilly could feel it against her small butt. She would purposely wriggle a bit, giggling, and would keep it up till Thomas stopped her. He would whisper in her ear that if she didn't stop he would make a mess in his underwear. Tilly would look at him with a sly look. And Thomas would sigh heavily, secretly wishing that he could just pull her pajama pants down and sink himself into her right then and there. But she was a virgin. And he didn't want to hurt her.

But there were other ways he relieved himself. When his sister wasn't home he would play their secret exploring game with his young niece. They would be together, in his bedroom, stark naked. Tilly would lie on his bed, spreading her legs. Plenty of times Thomas would sink his face between those thin legs and suck her to his hearts' content. And Tilly would have an orgasm, her small body twitching and a deep moan escaping from her lips. After she had her cum, Thomas would lie on the bed and Tilly would suck his hard adult cock till he came. The cum would explode from the tip of his swollen member, drenching her sweet innocent face with his sticking sperm. Afterwards, Tilly would lick him clean.

But, this coming weekend was going to be very difficult for Thomas. His sister was going away for a pleasure weekend. She had wanted a break from being a mom for just one weekend. He would be totally alone with his young niece. And he knew the temptation to fuck his niece would be overwhelming.

On that Friday, after coming home from work, he met up with his sister just as she was getting ready to leave. She was already packed and waiting for her ride to come. Tilly was with her, sitting out front with her mother. When she saw her uncle she ran to him, hugging him tightly. Thomas lovingly returned the hug. As he walked up to his sister he smiled warmly.

"Ah, you're ready for your vacation weekend, aren't you?"
"You know I am." His sister responded. "Dinner is already done. . It's sitting on the stove. Tilly already had her dinner and I left money on the counter for takeout food for the weekend."
"Thanks, sis." Thomas said. He was thankful that she had cooked. He wasn't one for cooking.
Just then a car pulled up. Two women were in the car, and waved to them.
"Great! They're here."
Thomas picked up her small overnight bag and walked his sister to the car. His sister quickly got in and Thomas put the bag in the trunk. Tilly followed them.

"Have a good time, Sis."
"You too. Don't let Tilly drive you nuts."
"Aw mom!" Tilly complained." I'm not gonna' give Uncle Thomas any problems."
"Yeah, right." Her mother said. She gave a sly look at Thomas. "Enjoy your weekend."

Thomas was puzzled by her look. But he shook it off and waved goodbye as the car drove off. After the car drove out of their line of vision, Tilly went up to her uncle and took his hand..........(cont)
