Anna knew she wasn't suppose to be out of her room after her parents put her to bed but a strang noise coming from her sister's room woke her up and she wanted to investigate. She padded down the hallway to Macy's and peered through the crack to her sister's room and saw her Daddy and her sister playing. It was much to late for her sister to be playing though wasn't it? Even though Macy was twelve and got a later bedtime than her it was still past both of their bedtimes. She was about to go in when she noticed her Daddy was grunting and her sister was whimpering painfully.

Anna's eyes grew wide when he finally saw that her Daddy and her sister were not playing but he was laying on top of her and thrusting slowly. Macy's eyes were edged with fear and pain and were spilling silent tears. Her arms where stretched to either side of her body and tied to the bedposts, in her mouth was the underwear that she had been wearing that day. Anna tries to back out of the room quietly but stumbled on something in the floor her Daddy turned and saw her. Anna wanted to run but was to afraid and her legs refused to move even as he began to move toward her.

"Anna baby I'm glad to see you, do you want to join me for a little midnight snack?" he asked grinning

"I'm sorry Daddy I'll go back to bed." she tried to turn but he pulled her back. Baby I think I have a better idea. He pulled her head towards his cock that Anna just now noticed jutting out. It looked monstrous to her tiny eight year old frame.

"Now baby you are going to put this in your mouth and not make a sound or I'm going to punish your sister okay?" He stared at her and waited for a response.

"Okay Daddy," Anna replied fearfully. Why was her Daddy doing this to her? He slowly thrust out his cock and rubbed it on her lips before she opened her mouth and took what she could inside. He work a little at a time in until she grew accustomed to his size. She was frightened of the jerking hard cock but was worried more about her sister. He then began mouth fucking her until he felt nearly to the brink of cumming when he pulled of he wanted to save his cum for her virgin pussy but was going to have some fun in the mean time. He led her over to the bed where her sister lay tied up and demanded she undress in front of Macy or she would get a spanking. Slowing the eight year old girl pulled her night gown over her head and then pulled down her princess undies. She stood totally naked and tried to cover her bare breast but her father got there first.

"Oh baby don't you cover these up they are too delicious to hide," he whispered. He took one tiny bud into his mouth and sucked and nibbled on it. Anna had never felt any thing like this before and a warm unbelievable feeling grew in her stomach. She let out a tiny moan unwillingly and her father took that as sign to move downward. He placed Anna in front of Macy's exposed pussy and told her to copy his actions. He dipped down into her tiny hairless pussy and began licking the outside and then slowly inside. She had a sweet taste and he wanted more he probed her virgin hole and then brushed her hard clitoris her sister and Anna both moaned at the same time. The more her flicked and licked the tiny nub the juicier she got she had about reached the point of ecstasy when he pulled it back and he heard a whimper of disappointment.

He stood up behind her and told her to keep lapping her sister's pussy. He rubbed his cock on her tiny hole until it was good and slippery then without warning he thrust in. She screamed out but he slapped her across her ass then she quieted to painful grunts and whimpers. After a few thrusts he emptied his load into her tight pussy. He then made her climb over her sister body and made Macy clean up Anna cum dripping pussy as Anna cleaned her father cock.

He left the room after threatening them with punishments. Anna untied Macy and they found comfort in one another over the years becoming secret lovers after every night with their father.
