Michael stood in the shower, water running down his body, trying to wrap his head around what had just happened. As he was washing his and his nineteen year old daughter's cum from his body, images of her, moaning and shuddering in orgasm while riding his cock, filled his mind. His body was beginning to react again, blood rushing towards his crotch, so he tried to push these thoughts away and finish washing.
A few minutes later he walked in the kitchen to find Kate. Like him, she didn't bother getting dressed after she showered. She had her back to him, preparing something to eat, and he took a minute to admire her round firm ass. 'What have I got myself into?' he thought.
"Hey," he said finally to draw her attention.
"Hey, Dad!" She turned to face him with a smile. "Are you hungry?"
"Sure." He paused for a second and continued, "Listen, Kate, we should talk."
Kate saw her father's serious expression and her face fell. "Oh, Dad, I thought we said no guilt trips."
"I can't help but feel guilty about the way I feel, Katie, but it's not just that. I want to make sure you are okay with it. I wanted us to talk now that we both have a clear head. I need to make sure you're okay with what happened."
"You seemed pretty sure thirty minutes ago," she teased.
"I was. I really felt that I was. But you know I wasn't thinking entirely with my head at the time."
Kate giggled.
"I'm serious, Katie," Michael continued, "I need to make sure that you -- we understand what's at stake here."
"I know what the problem is, Dad," Kate said, "you still see me as the innocent little girl I was before I left for college. And you are right, I was innocent then, but things have changed. I've had a lot of sex while I was away, and I do mean a lot. You're not corrupting me or taking advantage of me. I'm physically attracted to you, you obviously are attracted to me so we fucked. It's just sex, please don't make a big deal out of it."
"It became quite clear to me during the last hour that you're not an innocent little girl", Michael replied with a smile, but tried to turn serious again. "That's not to say I won't need some time to get used to it. And there are other things that concern me, mostly any harm that this might cause you on an emotional level. Not to mention it's illegal."
"Okay, for starters, the law can fuck off as far as our personal life if concerned. We're both adults and we can do whatever the hell we want, as long as we don't hurt anybody. Okay, we'll have to be careful, obviously, but other than that I don't see a problem."
"I guess, but -."
"As for your other concern," she interrupted, "there's no way you'll hurt me emotionally, I have complete trust in you. I understand that if this was about romance it could get too complicated but I'm not 'in-love' with you. I still love you very much as my dad, but this is about sex. It's about lust. Like I already mentioned, I'm not new to sex, I've been exploring my sexuality and I've tried quite a few things this last year. But what I felt out there with you is a totally new feeling. The connection we share and the safety I feel with you cannot be replicated with anybody else in the world. Not to mention the taboo aspect of it, just thinking about it gets me horny out of my mind. I suspect you feel the same way, so why deprive ourselves of this feeling?"
"Okay, slow down there." Michael saw that his daughter was getting riled up and tried to put her at ease with his tone. "Trust me, it was quite overwhelming for me too. I don't regret it, but we got caught in the heat of the moment." He was trying really hard to be the responsible parent and needed to slow things down and try to make sense of all of this. "It would be quite a big step if we decided to continue. All I'm saying is to give it some time to make sure it's what we want."
"Fine!" Kate shot back, visibly upset, and turned her back to him to continue making dinner.
"Okay, now you're being a child. I only want what's best for you, sweetie."
"Whatever." She barely acknowledged him and started chopping vegetables with a great deal more hostility than necessary.
Michael let out an exasperated sigh and walked out of the room. It pained him to see her like that but maybe it was for the best. He needed to let things cool down.

They barely exchanged any words for the rest of the evening. Michael tried to strike up a conversation during dinner by complimenting her cooking, but it was met with a simple emotionless 'thanks'. Eventually, he gave up and gave Kate some space.
Later that night, they found themselves sitting on opposite sides on the couch watching TV. They'd both gotten dressed by then as the mood wasn't quite right to walk nude around the house. Michael wore a pair of boxer shorts and Kate had chosen a plain white t-shirt and cotton panties.
The show they were watching was actually quite good and managed to distract Michael helping him momentarily forget the fight he was having with his daughter. He was so engrossed in the story that he never saw Kate coming as she pounced at him.
She jumped against him and hugged him tightly, her head resting on his chest. "I'm so sorry, Dad, I was being stupid."
"It's okay, pumpkin." he said and caressed her hair, after recovering from the initial surprise. "It's my fault, I should've stopped it sooner."
"No!" She raised her head and looked him in the eyes. "Dad, you didn't do anything wrong, please believe me!"
"I'm not sure about that, Katie. What if your mom finds out?" Michael asked, suddenly terrified at that prospect.
"Mom should mind her own fucking business. She made her choice back when she cheated on you, and I'm an adult, so she doesn't have a say in this."
"Katie, cut her some slack, it's more complicated than that."
"I know... " Kate sighed. "You know I love Mom, but she did betray you, so I stand by my previous statement."
"But- "
"Just forget Mom. You were right, we should take it slow, but it wasn't a mistake. It was the most intense and beautiful experience of my life, I'll never regret it!"
"I truly hope that's true, sweetie."
"I promise, Dad. You're the best dad ever, you don't need to worry." She pulled down his head to give him a big kiss on his cheek.
Michael still had serious doubts, but his daughter's words managed to ease them enough to lighten his mood. Kate cuddled in his arms as they resumed watching TV.

The following days, as agreed, they refrained from any sexual behavior. The incident with his daughter was constantly in Michael's mind, fueling his fantasies, and knew he could never look at her the same way again. She wasn't a naive innocent child anymore, she was a sexually mature woman. But, to his great relief, their relationship had remained intact.
