FaceTime can expose secrets

My daughter has been studying abroad for several months now.
 We FaceTime her several days a week, since she is home sick.
 My wife had gone away for a girls weekend.
It was late Saturday afternoon, raining so was enjoying a few drinks.
 Decided to watch some porn movies, since nothing good was on TV.
 Went on the adult channel and started watching a favorite, older woman seducing a younger girl, first time lesbian experience.
 Had a few drinks and was about an hour into the movie, had my silicone pussy and lube out working my cock.
 Suddenly my laptop buzzed, scared the shit out of me.
 It was my daughter trying to FaceTime, I ignore it at first, but the second time I put my movie on mute and answered.
 My daughter started talking, and I was half listening and watching the movie, because I was so close to coming, I just wanted to finish.
 Then I heard Dad, Dad, what are you doing? 
I was startled, and accidentally hit the unmute button.
I was trying to answer my daughter, when loud moaning was going on.
I quickly found the remote and mute the movie again sand paused it.
 My daughter asked what I was doing? You seem preoccupied with something.
I told her just a movie was on, 
She said it sounded like someone moaning.
I said no I don’t think so, I was embarrassed, that I just didn’t turn it off right away.
 I didn’t know what to say, she broke the silence by say.
Were you watching porn ? 
I said no I wasn’t, 
She said it sounded like someone moaning, and by my shoulder movement, like I was jerking off.
I said absolutely not, she seem annoyed, angry, and hung up.
Well that ruined the mood and I went outside.
My neighbor was out, so went nextdoor and had a few beers with him.
 I went home close to midnight, and was buzzed, and horny.
So put the movie back on and started jerking off again.
Suddenly my laptop buzzed, I jumped again, damm it was my daughter again.
It was late, which was strange for her to FaceTime, knowing we are usually in bed at this time.
I started FaceTiming with her after I made sure I turned the movie off.
 She said am I bothering you?
Were you sleeping?
I said no I wasn’t sleeping, I had just came home from nextdoor.
That I had a few beers with the neighbors.
She said, she was sorry that she hung up earlier.
She said she was angry at the thought of me watching porn, fantasizing about other women.
When my wife was gone.
I apologized, and didn’t really know what to say.
Then she asked, what type of porn did I watch.
I didn’t really answer, she said it’s ok, she knows it normal for men to watch and fantasize.
After continuously asking and said you’re not into gay stuff are you?
I said no, no not at all, I finally said it was lesbian movie.
She so oh really, like what type of lesbian movie turns me on ?
I confessed that, an older woman seducing a younger girl into her first time was my weakness.
 She said really 
I said I am sorry, we really shouldn’t be talking about this stuff.
She said know , I want to know what you enjoyed.
Then she said, have you and mom lived this out ever ?
I chuckled and said, no, there’s no way that would happen.
She said had I ever asked mom, if she would try something like that.
I said no I hadn’t, and I really don’t think she would.
My daughter said that I should ask her, maybe she would surprise me.
I said I really don’t think she would, we haven’t had any, for over ten years.
My daughter said, what ? That’s bullshit.
I reassured her it wasn’t, and that why I watched porn sometimes.
My daughter then said, do you want to know something?
I said like what ?
She said, I’ve been touching myself while we been talking.
I said really, why ?
She said that she got turned on, thinking about me jerking off.
And when she heard it involved a younger girl’s first time with another female, it reminded her of a girl she met at a party.
I said really, and did you and this girl do anything?
Now I was turned on by the idea, and as I listened to my daughter explain what happened. I started jerking off.
My daughter finally asked, are you jerking off again.
I confessed that I was, she said me too.
She said, would you like to watch me?
I was shocked that she would have this idea.
She said it would turn her on, knowing I was watching her.
I said sure, let’s give it a try.
She moved her laptop so that I could see her whole body.
I watched as she took off her clothes, and started touch herself.
She asked if I could see, I said yes a little, but it was dark to really see well.
She got up and turned a light on across the room.
My mouth dropped open, when I saw her laying on the bed, naked.
I never noticed what a great body she had.
I suddenly had a stronger interest , I was really hard.
She asked me to talk to her, tell me what I wanted her to do.
What turned me on.
After some time had passed, she asked if I wanted to see her use a toy ?
I said you have a toy ?
She laughed, and said a girlfriend of hers gave it to her as a joke present. That she kept it, but never really used it yet.
I said , so it would be like your first time?
She said yes, so it would be like our first time.
She went and got her toy. Then asked if I could move the laptop, so that she could watch me too.
 Caught up in the excitement, I agreed.
We were watching each other touching ourselves, then she said I am going to demonstrate how I would give you a blow job.
My mouth dropped again, my little girl knew about all this stuff.
I was really turned on, but also wondering how, when did she learn about this stuff.
As she walked me through how she would tease my cock with her tongue and then slide her lips over it. She demonstrated with her dildo, I was stroking my cock, she stop, to say that she liked how big my cock was, that she liked knowing I was so turned on.
Then she asked if I would tell her, what I would be doing, if she let me fuck her.
I started telling her, how I would tease her, slowly push my cock inside her.
She started using the dildo as if it was a real cock.
My voice got weird as I was so turned on, I was ready to come.
She started moaning loud, say yes, daddy, yes fuck me hard.
She was fucking her pussy hard with the dildo.
I was jerking off, listening, I could hear how wet her pussy was.
Then she said, daddy I am going to come, I am going to come.
I want you to come with me.
We both came, our bodies shaking, legs feeling weak and trembling.
We were both quiet, just listening to the heavy breathing.
Then my daughter said, I better let you go, she said I really enjoyed myself daddy.
I said I had too, 
She said maybe we can do this again when mom’s not home.
I said I would love to.
