Shelby began to undress. Life was good, she thought to herself. She had a good boyfriend, for once, in Eric and she loved her mother and father. Her sexual relationship with her mother showed no signs of cooling off. The threesome involving her parents had worked well and seemed to be a one-time thing.
The fact Shelby lived in their house while attending college apparently didn't bother Lisa and Frank and she tried to pay them back by helping out as much as possible. She certainly couldn't afford to pay rent, yet. And when tempers grew short between them, she normally backed off.
She sat on the edge of the bed in her bra and panties, her back to the bedroom door which she had not completely closed when she entered the room. In the hallway, Frank was headed for his bedroom. He saw the light leaking from Shelby's room and slowed. Before passing the door, he stopped and peeked inside.
He saw her hands unhooking her bra. Frank watched as his daughter pulled it off. Her breasts were hidden from his view, but images of them from their time together filled the void.
Shelby pulled off her panties. She stood and walked slowly to her dresser. Frank stared at her perfect little ass. The full, round cheeks once rested on his legs while Shelby slid up and down his erect cock. Frank rubbed himself at the sight and the memory.
She took just long enough to find a t-shirt that Frank was getting hard by the time the shirt slid over her head, down her back and over her sweet ass.
He suspected she was about to turn, so Frank quickly passed by the door, turned into his bedroom and went straight to the master bath. With the door closed and locked, he opened his pants, reached inside his boxers and pulled out his cock.
He closed his eyes and summoned a picture of Shelby's naked body. Frank saw her breasts and hips and ass. He imagined her tight cunt once again squeezing his cock. His fingers gripped the cock tighter, pumping it rapidly.
It used to take him an eternity to cum before the threesome with Lisa and Shelby. Now he found himself able to cum in an instant just thinking about his daughter. He thought about his cock inside her mouth, Shelby's tongue licking the entire length of his shaft.
Frank leaned against the sink, his cock pointed over the edge. He grunted one time, stroked harder, and felt the first gush of cum flow through his cock. He visualized sucking Shelby's luscious tits, cum flowing freely now into the sink. He thought about fucking her from behind and came some more.
Finally, he was done. After resting for a second, he turned on the water and cleaned out the sink. Frank caught his breath, flushed the toilet just in case Lisa was around and left the bathroom.
Shelby lay in her bed, one hand lightly rubbing her clit. She stared at the roof thinking about what she just saw—a reflection in the mirror of her father peeking around the bedroom door while she undressed. Was he hard? Did she interest him more than she knew?
The threesome had been wonderful, but she didn't think it would go much farther. Shelby had done it to jump-start her parents' love life, and it seemed to work from what Lisa had told her. Now this.
Her other hand rolled a nipple between two fingers and she felt the moisture building in her pussy. She rubbed her clit harder and faster.
How could she find out if Frank wanted more from her?
In the darkness of her bedroom, Shelby arched her back and tried to muffle the sounds of her orgasm.

It was unusual for Shelby and Frank to be alone in the house for an extended period of time. But Lisa was shopping all day with girlfriends at an outlet mall an hour away and Eric was watching football with 'the guys', so Shelby felt no shame as she put on a bathrobe after her late morning shower and headed downstairs. Actually, it was by design.
"Hi, Daddy," she said as she bounded into the kitchen.
"It's about time. Do you sleep all day every weekend?"
"This is early," she said, reaching inside the refrigerator.
Frank finally noticed what she was wearing, taking a second look at the large opening in the fluffy robe above Shelby's waist. It was obvious she didn't have a bra on. He couldn't tell about panties.
"Do you have plans?" he asked.
"Nope. Just lying around. How about you?"
"Nope. I'll watch games on TV, I guess." With food in hand, Frank walked into the family room.
Shelby took a chair facing him and, when he wasn't looking, opened the robe between her legs just a little. She spent the next fifteen minutes eating and purposely avoiding his glances.
When she was done, she joined him on the couch. She curled her legs under her and leaned on a pillow.
"Are you and Mom OK?" she asked
"What do you mean by OK?"
"You know," she said timidly. "Did our threesome help?"
She knew the answer from talking to her Mom, but wanted to play with her father's mind a little bit.
"Yes." He looked away from the pre-game show and over at his daughter, comfortably covered...somewhat...by her robe.
"That's good. What did you like best?"
Shelby's smile was one he had never seen on her face before, except perhaps the night she made him cum.
"Maybe the blindfold. But I enjoyed it all," he said.
"The blindfold? I thought maybe you liked to watch." The vision of him in the hallway outside her door flashed through her mind.
"Watch what?"
"Me," she said confidently. She stretched out a leg, letting it hang over the edge of the couch. It was uncovered up to her hip.
"Well, I don't...you know," he tried to think of something to say that wouldn't offend her.
"Do you think I'm pretty, Daddy?"
The child-like sexiness of Shelby's voice caused Frank's already hardening cock to twitch.
"Of course I do, hon."
Shelby moved her exposed leg so her foot and calf rested on his thigh. One side of her robe covered her pussy, barely, while her breasts became more and more exposed with each of her movements.
"Do you ever think about me naked?" she asked.
She touched his crotch with her toes.
"No."
They both knew he was lying.
"I think you do," Shelby said calmly. "I think you are right now."
He could only look at her, the lust evident in his eyes.
Shelby stood up in front of the couch. She brushed her hair back with both hands, her robe stretching open another couple of inches. Then she pulled at the loose knot holding the robe's belt together. As it came apart, she held the two sides of her robe together so it only hinted at what lay behind.
"Pull down your zipper," she ordered.
Frank did so.
"Take out your cock."
Fear and desire fought each other inside his head. His heart pounded as he pulled the semi-erect shaft out.
Once Shelby saw it, she turned and opened the robe at the same time, teasing him with a momentary glance at her nakedness. Then she slowly pulled the robe off her shoulders and let it fall to the floor. Frank stared at her naked back and ass, the same view he had in her bedroom. This time, he stroked his cock.
Shelby ran her hands over her exposed ass cheeks, squeezing them and leaving imprints of her fingers in the tender flesh. She touched her breasts, then moved her hands down to her pussy. She bent at the waist and let him see her hands caress her wet cunt and clit.
He was hard now. Very hard.
She put on a show for another minute or two, making love to her body with her fingers. Then Shelby turned to face her father. That wicked smile returned when she saw his erection. She played with her breasts, pulling at the nipples and moaning quietly.
"Ummm. Don't you wish you could taste these tits?" she taunted him.
Frank stroked his rigid cock faster.
"And do you want to put that big, thick cock inside my pussy again?" She rubbed her clit and used a single finger to pull moisture up from her cunt to it.
"I want to feel it deep inside me, stretching my cunt apart."
Frank was ready to cum. But where was she going with this?
"Do you need to cum, Dad?"
Frank nodded, almost unable to speak.
"Then cum. Cum all over yourself. I want to watch, just like you want to watch me."
Frank leaned back on the couch, his cock pointed up and towards his chest. He took one more look at his daughter's delicious body, her legs spread wide apart, and groaned. His ass came off the couch as the first shot of cum flew into the air and landed on his shirt. Then another. And another.
Shelby smiled. Her father's eyes were closed as he pumped his cock, shooting stream after stream of cum onto his shirt. She silently pulled on her robe as her father finished cumming.
He lay motionless on the couch, his limp cock hanging out of his boxers. Frank watched Shelby walk out of the room, her little ass swaying underneath the robe.

Shelby loved the control she felt during the episode with her father. It was a different pleasure than she got from cumming during sex. It was more powerful; longer lasting. And she wanted to experiment with it some more.
The first opportunity came the following weekend when everybody was going to be available—Eric, Lisa and Frank. Shelby had never 'officially' been told of the liaison between her boyfriend and her mother. But she had her suspicions. If, in fact, it had happened, it would only improve the chances of pulling off her next control experiment.
She spent the week setting it up by making sure everybody was going to be at the house on Saturday afternoon. Nobody had anything they had to do. They'd have plenty of time on their hands.
Shelby didn't want to leave anything to chance, so she worked on her mother the most.
"Eric's coming over Saturday. I hope it's to see me and not you," Shelby said with mock jealousy in her voice. She and her mother were on the back porch, late in the evening.
"Ha! What do you think?" Lisa said.
