I almost opened the door and stormed in to show you I did want to have you both together. There were a number of considerations preventing me from taking such a step. First, it would get progressively harder to keep the volume down, increasing the risk of your mother waking up. Second, I was self-conscious about eavesdropping on you, I'm not sure why, it could have been my self-esteem as a conductor of your sexual upbringing. Third, your feelings could get hurt if I showed too much interest in another girl, which was not the case; she was interesting most of all as a way of making all the more pleasurable your attentions. All of those thoughts drove me back to the marital bed.

Next morning having breakfast was an ordeal. Having to handle a stubborn erection, even though there being a visitor prescribed the wearing of a regular daytime dress and not tell-tale pajama pants, and having both of you so close together, right in front of me, right at hand, prompted me to be in a hurry for us to leave.

All through the day my mind wriggled in anticipation visualising your full anal debut, the ritual Angie, your little vixen girlfriend, had given as a sign of your readiness to please Daddy in this new cooperative way.

"Our next time alone together Daddy will give you a big surprise my little princess." I told you at the following goodnight kiss.

"I love your surprises Dad, you always make them so nice."

As usual you did not request any further information, your smile declaring your eagerness for reaching the time it was to be unveiled.

When the day came, your excitement during our drive home from school reached new heights. To compound things, your mother’s regular business trip had been moved ahead due to a holiday, so our usual two-week wait had lengthened one more.

Once home I took you by the hand to your bed this time, gently undressed you and laid you down, sowing a carpet of flowers on the fresh pasture of your skin with my kisses. It was a treatment you hadn't received before, not to this extent, and you may have thought this was my surprise. You closed your eyes and abandoned yourself to the feeling, your body flowing under my hands. While following up with your clitoral and anal stimulation, I made several short interruptions to undress myself by stages, each one signed by you looking back, wondering if it had come to an end, each return bringing you to further depths of pleasure.

Once naked I climbed on your bed, spread open your legs and lifted them up. With my fingers I smeared the lubricating juices flowing so generously from your vagina onto your anus. Then you felt it coming, my phallus running on the inner face of your upturned thighs, making your breath pick up speed in anticipation. I reached my destination and held it with my hand to exert a little pressure. Your sphincters were trained to relax on demand by then, so the first approach pressed forward with ease up to an early point. It was much better for you if I went back, and only then kept pressing a little bit further in each move. Your breathing was getting harder all the time and your sidewise turned face blushed intensely. Your mouth was open wide and a wet spot was forming from your saliva on the sheet.

As my phallus kept on its drive, you lifted your head a bit and with a muffled voice you made a long wailing call for Daddy. You clenched the sheets and twisted, now breathing laboriously. When my penetration had gone more than halfway through, you pulled the sheets towards you and let out an undulating call, waves of intensity, followed by punctuated exclamations in the same line. I ejaculated in your rectum and pulled off. Your anus was dilated and semen was dripping out. There was no blood, I had done it with no haste and in a gentle manner. Relaxed, you let your weight fall down on your bed and gave out a deep sigh. I went down the bed and knelt besides it, caressing you. There were tears running down your face. I hadn't grown callous, I had hurt you.

"My baby, my sweet little baby girl. I'm so sorry. I didn't mean to hurt you. I'll never do this again to you. Please, Princess, forgive me. You know I keep my word."

I expected myself to keep my word.
