The first time I found my 22 year old daughter Katie in a compromising position, I did what any normal father would do, got her out of it as quickly as possible. I'd just gotten home from work, and heard the back door slamming as soon as I walked through the front door. I might have gone to check who it had been, if I hadn't heard loud moaning coming from up the stairs. I followed the sounds to my daughter's bedroom, then got the biggest shock of my life when I threw open the door. Because, there was my daughter, tied spread eagled to the bed, wearing nothing but a blindfold, with vibrating butt plugs in both her pussy and her asshole, and a ball gag in her mouth. I'll admit that I stood there for almost a minute, while the picture of her writhing in sexual ecstasy burned itself into my retinas. Then I started releasing her from her captivity, going for her hands first, so she could undo the rest of her bonds herself, before damn near running from the room, so she wouldn't see how much the sight had aroused me.
When Katie came downstairs, I hoped that seeing her dressed would help erase the sight of her naked body from my mind. But what she was wearing did the exact opposite, since it highlighted the areas I was most trying to forget. Her tight white t-shirt, with no bra on underneath, made the fact that her nipples were still hard quite obvious, and drew my eyes to them. And the even tighter khaki shorts, readily displayed her camel toe as well as showing a lingering dampness in her crotch area. I admonished myself for thinking those things about my daughter's body, and raised my eyes to look at hers. Then I said that while I wouldn't interfere with her personal life, she should tell her boyfriend to at least stay long enough to let her loose, if he was going to tie her up like that. Katie said her boyfriend hadn't tied her up, because she didn't have one. Then when my eyebrows raised, she said it wasn't like that either, at least not all the time. She was interested in men too, but the one she wanted wasn't interested in her that way, yet. So her friend had tied her up to take pictures of her, to send that guy, and she'd just panicked when I came home and forgot to untie her first.
I dropped the subject then, because we heard her mother's key in the door, coming home from her garden club, and I definitely didn't want her to know how I'd found our daughter. Her mother had a strict Catholic upbringing and was a lot less tolerant of other lifestyles than I was. So, unless we wanted to listen to a lecture about the evils of homosexuality, or any other deviant activities, it was best to keep this secret between Katie and I. Except, by not continuing our talk, and telling her that letting her father see her like that was wrong, it shouldn't have surprised me to find her in a similar position a few days later. This time though, there was no ball gag in her mouth, so that when I started untying her hands, she could tell me she was close to cumming. And that she'd like me to wait until her orgasm was finished before I untied her. I could have done three things at that moment, untied her anyway, and left the room until she was done, or at least turned my back so I wouldn't see it.
Instead, I just sat there on the edge of the bed, and watched her beautiful body go into the throes of her orgasm. Katie looked just like her mother when we first got married, firm medium sized breasts with huge nipples, a flat stomach, and from what I could see past the butt plug in her cunt, thin pussy lips and a clit the size of a one carat diamond. And while I'd seen the same facial expressions, when my wife came, I'd never seen how the rest of her body reacted, since it was always under mine. Now that I was watching Katie's body, I was sure my wife's tits swelled up just as much, and along with the rippling of her stomach muscles, I also figured my wife's clit played the same rhythmic hide and seek Katie's did, when her hips bounded up off the bed. And the wailing sound was so similar, that I almost kissed Katie the same way I did my wife, to keep the neighbors from waking up.
When her body relaxed again, I resumed the task of untying her, and when I got her hands undone, they circled my neck to pull my face down for the kiss I hadn't given her. Then she slid her lips to the side, to nibble on my ear, and whisper for me to tie her hands again and make love to her, like we both wanted, so I could cum too. Those words were like a glass of ice water thrown in my face, and I pulled back so quickly that even Katie's arms around my neck didn't stop me. And I ran from the room in total horror at myself for what I'd almost done. Because if Katie hadn't talked about tying her up again, I probably would have done what she wanted on my own, since one of my hands had already been squeezing the breast that was under it. Unfortunately, Katie took a little longer to get dressed this time, and her mother walked in the door before I had a chance to talk to her.
My wife sensed something was up between us anyway, because I couldn't look Katie in the eye at all that night, and she called me on it when we went to bed ourselves. Of course, I couldn't tell her I'd almost fucked Katie, but by playing 20 questions and gauging my reactions, she did figure out it was related to sex in some way. Meaning she thought I'd just found out that Katie had a girlfriend instead of a boyfriend, and told me to give our daughter a break. I was shocked at her saying that, and I reminded her that she was the one always preaching about the evils of homosexuality. She gave a sad sigh and said that like all high moral ground perspectives, hers fell apart when she found out that our Katie was that way. And after listening to Katie, instead of just lecturing her, she'd started understanding a little more about how these things happen. Katie wasn't a lesbian anyway, although she had been making love to women. She was just afraid of men, because all the ones she dated in college had been too forceful with her. And she would have gotten raped after one of those dates, if her roommate hadn't come home when she did, which was how she first learned about lesbian lovemaking.
The good news was that she did like this one guy, and thought he would be perfect for her first try at normal sex. But while the guy liked her, he wasn't interested in her that way, and she was working on changing that. At this point, I was able to finally say part of what was bothering me, that I knew who Katie was chasing, and that he was definitely the wrong guy for this. My wife said she didn't know who it was, although she trusted Katie's judgment enough to let her choose for herself. She was an adult now, and knew better than we did who was right for her. And even if this guy was a mistake, it wasn't our job as parents to stop her, it was just our job to help her if she got hurt, and make sure she learned from it. So, she wanted Katie and I to kiss and make up, and she wanted me to fully support our daughter's decision on this, and she didn't want to hear another word about it.
The first of the pictures Katie's girlfriend had taken arrived on my phone the next day. And when I wrote to tell her to only send them to the guy she was trying to interest, her answer was the worst one there could possibly be. It was that she had only sent them to him, and for me not to lie and say I wasn't interested. Even though I hadn't made love to her, my kissing and the way I'd played with her tits, told her there was enough interest for both of us. She needed to learn how to make love to a man, and I was the only one she trusted to teach her without hurting her. Not just how to fuck either, because she'd watched plenty of porn and knew there was more to sex than just plain fucking. And she wanted me to teach her everything they did in those movies, like how it felt when I stuck my cock up her ass, and how it felt and tasted when I came in her mouth. So, she would be waiting for me, just like in the picture, to start her lessons as soon as I got home.
I wish I could say I was a strong enough man to reject my daughter's offer, but what she was offering me was just too good to resist. Not only was she offering me the same body her mother had captured me with 23 years earlier, she was also offering me more things to do with it than my wife had ever offered. As I said before, my wife had puritanical views on sex, which meant mostly just missionary position, and letting me eat her pussy every now and then. Even that had taken me two years to get, because oral sex of all kinds had been at the top of her list of deviant and evil activities. It had taken me getting her drunk on wine, and damn near raping her with my mouth, although she never told me it was evil anymore. Now Katie was willingly offering to let me do the things my wife still considered evil. So any reservations I had about fucking my own daughter went straight out the window.
I rushed straight home from work, to give us the maximum amount of time for Katie's first lesson, and found her just as she'd promised, tied to the bed again, with the blindfold over her eyes, and the butt plugs buzzing away in her pussy and asshole. When I entered her room, she asked if I was going to run away again this time. And as I raised her blindfold to look into her beautiful green eyes, I told her that Daddy wasn't leaving until his little girl became a woman. Then I leaned down to kiss her, but she stopped me when I went to untie her hands, and said that her orgasms were a lot more intense when she was helpless like this. Besides, she went a little crazy when she was cumming, and with her long nails she'd leave too many marks to keep this a secret from Mommy. Then my lips went back to hers and my hands, knowingly this time, went to play with her awesome tits. And the way she was fighting against her bonds from just that little stimulation, was so sexy, that I knew I'd love making her really fight them later.
