Daughters Fantasy

A week ago I was locking up the house for the night my wife was in bed, all the lights were off and as I passed my daughters bedroom I heard soft moans, her door was slightly open but nothing was visible just her moaning softly, yes Daddy yes oh yes I heard the bed creaking a little she was clearly masturbating calling my name saying yes, over and over, I was rock hard I quietly made it down to our bedroom where I creeped under the covers mouth straight to my wife's c**t sucking and licking her like crazy turning her to doggy pos and pounded her pussy till I exploded wads of cum inside her and all this time seeing my daughters face saying yes Daddy yes fuck me. Shit now what do I do, my daughter is only fourteen. Fifteen next week.
