It had been a day like all the others (except that my daughters were coming home for a visit) in my life since my wife died and left me to bring up our twin daughters on my own. The girls (Cathy and Megan) were only four when she died in an accident, and for the first six months or so I made so many mistakes that I thought Children's Services would step in and take them from me. Luckily with the help of some caring neighbours, I managed to get better at being a single parent, and my daughters turned out just fine. I spent as much time as possible with them and eventually got used to all the things that their mother would have done for them if she had lived; like buying their clothes and underwear, and even when it came time to get them their first training bras, etc., as well as give them "that talk" about the things that eventually change in their bodies, I seemed able to give them all the relevant information they needed.
During those years I spent a lot less time in my business and relied on my managers to do most of the things to keep it running, but when the girls went off to college at the start of the year I finally began to spend more time running the business, and thus was able to expand it in some areas. It was not that I was seeking to make an even bigger fortune, but more a way of getting over the loneliness when the girls left me and I felt I had been cast aside.
As they both had different goals, they went to Uni's in different parts of the country, and the only time they saw each other was when they returned during holidays to visit with me. Now, my daughters may be twins, but they are not identical in looks, but their bodies do like alike. That always made it easier for me to buy things for them as they both wore the same size and had similar likes to each other. They both took after me and were tall, for girls, as they were around 5'10" and both had beautiful blue eyes. They had celebrated their 18th birthday during their last visit home for a holiday. Cathy liked her hair short and Megan preferred hers down below her shoulders. They were both a 34C cup (remember, I bought their clothes for them most of the time), and they had slightly better then average figures then most girls.
As I had to pick them up at the interstate bus depot when they arrived around 7pm, I decided to take the afternoon off so that I could make sure the house was presentable for them. By that I meant that I wanted to make sure there were no Penthouse of Playboys lying around the house, or my underwear on the floor in the bathroom, instead of in the clothes hamper. Knowing I had to go out later to get them, I parked the car on the street and walked to the front door, stopping on the way to collect the mail.
When I walked in the door I looked around, and sure enough there were a few of my porn books on the coffee table, as well as the empty beer cans from the previous night. Since the girls had gone away I had become very slovenly in my household chores, but as I lived alone it did not worry me too much. I put the porn into the back of the cupboard and collected the empty cans and put them in the trash. As I walked back into the lounge room I thought I heard a noise coming from upstairs, and knowing there had been a few break and enters in our street lately, I crept silently up the steps to check the room.
Looking into the bathroom first I saw it was clear so I proceeded to Megan's room next and slowly opened the door and got the same result. Next I turned to my left and slowly opened the door to my room and checked, before going to check Cathy's room. Feeling I looked rather stupid in the way I was sneaking around, and realizing I had imagined the noise, I was about to turn away when I heard a low moan come from her room. My heart began to pound as I nervously, yet slowly, I reached for the door handle, but it was already open.
It was only open a few inches so I tried to see if I could see anyone from my vantage point but I could not. Slowly I pushed it another few inches, but still nothing. I was just about to push it wide open and demand the intruder's leave when my eye caught a movement. I looked up and could see them in the mirror. As I saw what the 'thieves' were doing I froze in my tracks. There, on Cathy's bed lay the two people. They were both young girls and they were naked. Not just naked, but they were in the '69' position and going to town on each other's pussy's.
I stood motionless with my eyes popping from my head as I watched these two young nymph's going down on each other. My cock began to twitch as my brain sent it a message and it came from its sleep. I was so damn angry that my home had been invaded, but at the same time I was getting so aroused by the sight before me. As I watched their antics, but only seeing an occasional glimpse of the bottom girls pussy and the naked back and bum of the one on top, I unknowingly began to rub my cock through my trousers, knowing that there was no danger to myself as these two were naked and not in any position to do a thing about me watching them.
At some stage it became too much for my bulging and straining cock so I undid my zipper and released it and went to work on pumping as I watched the intruders lick and suck each other. After a few more minutes I was near boiling point, and not having had a woman in my bed for almost two years now, I decided I was brave enough to barge in and demand they include me, or I would call the police. Just as I placed my hand on the door to push it open the girl on top rolled off and quickly turned to embrace her lover in crime and I got a quick glimpse of her face. It was Cathy! My own daughter!
It was a wonder they did not hear my heart rapidly throb and hear my gulp as I saw that they were not intruders, but my own girls. It took what seemed like ages before I could get my head, and my feet to work, and I was soon edging backwards and out of the door. I crept back down the stairs and pondered what to do. Should I wait until they are finished and pretend I did not know they were there? I then decided they would be too embarrassed knowing I had been in the house while they were entwined in each others pussys, so I quietly left the house and returned to my car.
Feeling glad I had not driven into the garage, which would have alerted them to my approach, I drove around the block a few times before deciding to hit the local pub for a drink and to think about what I had spied. As my second drink arrived my mind was racing, wondering if I should 'have a talk' with them about what I had seen, or even about the moral wrongs of what they had been doing to each other. By the third drink I was feeling more relaxed, as well as starting to tent my trousers as I pictured their delightful, yet naked bodies. By the time almost two hours had elapsed, as well as six beers in total, I knew it best to just pretend I had never seen a thing. My logic was that if they were that horny that they had to pleasure each other that I should be at least pleased they were not banging a few stray boys. I finished that drink and went to my car and drove home.
This time I drove into the garage and made a point of revving the engine once before shutting it off. I then slammed the garage door harder then needed just to make sure they had heard me arrive. I took my time and walked back and pretended to check the mailbox and then stopped and called out to my neighbour and talked for a few minutes about his day and general chitchat. Feeling the girls had plenty of time to get dressed and straighten the bed, I fumbled the keys in the lock and as I walked in I went to the kitchen and opened the fridge and took out a beer. I did not need it, but the girls knew my routine and I did not want to alarm them.
"Surprise Daddy!" they both called out as I entered the lounge room. "We both decided to come home early and surprise you Daddy!" Cathy said as her arms went around my neck and she hugged me tight.
"Damn girl, you almost gave me a heart attack! I thought I was about to be mugged!" I pretended to be surprised.
"Sorry Daddy, we were just both eager to get home and be with the man we both love!" Megan said as she took her turn at hugging me.
"Oh! So you girls have boyfriends now do you?" I joked with them.
"Yes Daddy, but like good sister we just have the one and we are happy to share his love and affection with each other," Cathy laughed.
Not being exactly sure if they meant what I thought, I pretended to be upset and annoyed at their news that they were sharing a boy with each other.
"So looks like I raised my babies wrong after all. I was so sure you girls would stay pure and chaste until you were married, and now you tell me you are both sleeping with the same guy!" I scolded.
"Don't be silly Daddy, we are both still virgins and you did raise us good. We mean that you are the one we love and we wanted to be with you as early as possible!" Meagan almost cried.
"Yes Daddy, we both missed you so much and were worried about you being alone here all this time. Why won't you go and find a woman and start enjoying yourself Daddy? You needn't worry about us any more, we are grown up and we know you need someone special in your life" Cathy said as she hugged me once more.
"You two may be all grown up, but if you ever scare me again like that I will put you both over my knee and spank you like when you were little and naughty!" I laughed back at them.
"Did you hear that threat Cathy? Hmmmm, I don't know about you, but I think I want to be naughty again so Daddy can spank me!" Megan giggled to her sister.
"Yes please, that would be so much fun and I think Daddy would enjoy spanking our bare bums now that we are older!" she laughed back.
This type of talk shocked me, as I had never imagined they would openly talk dirty like that in front of anyone, let alone their father. But it also dragged back a mental picture of their naked bodies on the bed a few hours ago.
"I think you are right there Cathy. Just look how quickly he began to bulge in his pants! He is already enjoying us being naughty like this" Megan laughed as her words sank in and it was me who was embarrassed.
"Ooooh! Daddy! Do you want us to take our panties off now so you can spank us?" Cathy asked in a little girl voice.
"Enough with this type of talk girls! Since when did you both grow foul-mouths?" I demanded.
"Come on Daddy, we are just joking with you!" Cathy started. "But you certainly seemed to enjoy the fun as well Daddy!" Megan added.
"Maybe so sweetheart, but you girls took me by surprise. But it has to stop now. Remember I am your father!" I exclaimed as I took a seat and hit the remote on the TV to take my mind away from their naked bodies.
