Sarah starts to work on Tom

As Janet turned to leave, she called back "I'm going down to make a full breakfast to celebrate our first morning all together. Be dressed and downstairs in 45 minutes."

Without thinking, Sarah immediately got out of bed at that command. She started to get some clothes and then caught herself. 'Why am I just obeying her? She just seems so authoritative and mature. I feel like a kid around her. It must be Tom's wish.'

At that thought she got moving, realizing that she had a window of opportunity to start working on Tom. She walked into the master bedroom. It felt like she was sneaking around where she shouldn't, even though this had been her room until yesterday! She almost get distracted by all the signs of Janet in the room, picking up her bra off the corner of the bed where she'd left it. The thought ran through her head - 'She's so much bigger than me, so prettier' - giving her a sense of inferiority and embarrassment while at the same time a tingle of arousal.

She caught herself. 'Not what I'm here for,' she thought, and went into the master bath. The door was partially open with a bit of steam coming out. She slipped inside to see Tom just stepping out of the shower. He paused drying himself when he saw her, and smirked at the sight of her standing there in her Hello Kitty pjs. "Hi Daddy," she said in a shy voice - not the tone she intended, but she couldn't help but feel that way, instinctively looking down at the sight of Tom's nakedness.

"Hi there pumpkin," he answered, wrapping the towel around his waist. "You shouldn't be in here. It's not appropriate. You're eighteen - far too old to just walk in on your father."

She **** herself to match his gaze and slowly walked forward. "I...I'm here to show you how much I love you..." she said hesitantly, like an inexperienced girl desperately trying to sound and look sexy. She internally cursed her pathetic attempt at seduction. Tom just watched her as she came up to him. "I don't know babygirl. How would you do that?" he said with a smile.

She dropped her to knees and pulled off his towel. She couldn't help but gasp at the sight. Though she'd seen it many times before, now Tom's penis seemed strange and mysterious. It was growing erect as she watched. She slowly reached out and it jerked slightly at her touch. She wrapped her hand around it, feeling like it was huge compared to what she remembered - she was just that much smaller now, her hand looking tiny in comparison.

She raised her head to look at Tom's face again, but she was unable to read his expression. It was almost as if she had lost all her knowledge of physical intimacy and sex. She felt completely unsure - but she knew she needed to make Tom feel their connection. Her own emotions were in a whirl as well. Her marital love for Tom was dim in comparison to the new sense of him as her father - but a father that she secretly longed for and wanted to please. She tried to smile suggestively, but at her uncertain expression and visible braces Tom gave a small chuckle.

"Please, let me do this. Just think, your girlfriend is downstairs. She could walk in on us at any minute. What would she say?" Sarah blurted out, trying to get Tom into it.

Her words must have had an effect. He looked at the door, then back down at her, his penis now throbbing in her hand. She licked him, trying to play with the tip. He made a small moan. "Oh, that's nice pumpkin. But you better hurry!" He stroked her head, running his fingers through her long hair. "Can you make daddy happy?"

She nodded. "Mhh..mhh," she tried to answer as he pushed into her mouth. She struggled to take him in, gagging some as she bobbed up and down on his cock. She quickly realized that she didn't know what she was doing, despite having giving Tom multiple blowjobs before. Her movements felt completely awkward and inexperienced as if this were her first time. So she tried to make up for it with enthusiasm.

Her efforts seemed successful. While the sensations weren't the best - her braces scraped him more than once - Tom was enthralled by her performance. Watching her attempt to get him off was in itself almost enough to make him cum. The thrill he got from her submission and humiliation got him harder and harder. He only lasted a couple minutes before cumming explosively. Sarah gagged and choked, popping off him so that the rest of his semen sprayed on her face. She continued **** for a few seconds, then looked up at him with a **** smile. "How was that Dadd.. Tom?" she managed to say.

Tom smirked again. "A for effort pumpkin, but D for performance. You'll have to do better. And practice will be hard with Janet here, so you'll need to be very sneaky." He narrowed his eyes. "And that's 'daddy' or 'dad', right? Only my girlfriend or wife gets to call me by name. And you're not that. You're just my immature, silly daughter."

Sarah looked down. "Yes daddy," she acquiesced.

He patted her head. "Good girl. Now go clean up. You can't let Janet see you like this now can you?"
