"What, you wanna join in or something"
Well, maybe it is unrealistic, but surely, it would be very hot if the other daughters also join. However, when I think about it: What about this:The mother (or the father) has some old porn video tapes or porn mags, showing the father "at work". Maybe father and mother even did some private porn just for fun. Of course the hid this stuff somewhere in a closet, but for some reasons, the daughters (or at least the oldest one) finds this stuff ...
(Edit 2: sorry, this became bigger then expected, better go to the toilet before reading this, it takes a while to get to the end)
As a basic idea (edit: it seems this could become a multi-part story, this would be part 1): Mom works in a virus laboratory. One day a virus escapes and Mom has to go into quarantine for a few days or weeks. So she calls home and tells her daughter to bring her some clothes for the next few days.
The daughter takes a suitcase or a bag and puts some clothes from the closet into it. Suddenly she sees a red box that she has never seen before. She opens it and sees a self burned DVD and some photos. On the first few photos, Dad has sex with another woman. The daughter is shocked to see her Dad with another woman - he is cheating Mom. But on photos that are very similar, Dad has sex with Mom. And then there are also photos where Mom and this other woman have sex. So it seems as if they made a threesome.
Now the daughter watches the DVD ... and it is similar stuff: Mom and Dad and this other woman having sex in many different ways. Some things on the DVD make it clear, that the DVD is pretty new. Like the new bed that her parents bought just a year ago is seen on the DVD.
However, the daughter can hardly believe what she sees. Her father doesn't have a huge penis, but he sure knows how to use it ... and he uses it many times. At first both women give him a blowjob where he shoots big loads of cum. Then he fucks both women in both holes, until they both cum. And Daddy still is not finished, he keeps on fucking them for quite some time. It's unbelievable.
The daughter becomes envy: so far she never reached an orgasm while being fucked by a guy, only when she fingered herself. Usually, the guys always came much to early ... and here on the DVD, she sees her Daddy bringing 2 women to multiple orgasms without using his hands or tongue ... just his dick.
While watching all this sex on the DVD, she starts to masturbate. After she climaxed she is somewhat shocked when she realized what she just did ... she masturbated while watching her parents during sex ... but then she starts to dream about how it would be if Daddy fucks her. Even anal seems interesting now (she never thought about giving it a try before). Sure it is forbidden, but if she would ever get the chance ....
So this would be part 1 - Daddy fucking 2 women and the daughter masturbating to it.
Part 2 would start with Daddy dreaming about his daughters. He takes a bra out of the laundry to see the size of her boobs. Also he starts to look through the keyhole. His fantasies become hotter and hotter and finally he can't take it anymore: he asks her directly. He expects her to get mad or something like that, but instead she smiles and accepts the offer.
It is the best sex that she ever had.
Her younger (but already legal) sister notices that something changed her sister. In the past she always had a bad mood (because of bad sex ?) but now the big sister is so happy all the time. Lil Sister asks her and Big Sister tells her that she had great sex, even including anal. Lil Sister is surprised because in the past Big Sister never dated any guys that have been good in bed (they talk very open about it, so Lil Sister knows about the bad sex life of Big Sister). She becomes curious and wants to know who this super stud is. Finally, Big Sister tells her it's Dad. Lil Sister can't believe it ... until she sees the DVD. So Lil Sister tells her, she also wants to join them .... and of course, Dad has no problem with that.
Don't forget the youngest of the 3 daughters. She just turned 18, but she is a tomboy, so she is still a virgin - and the way she behaves, she will be a virgin for quiet some time.
The 2 bigger sisters talk to Daddy about it: they all agree: her defloration should be something special. The sisters talk to her about sex and the tomboy tells them that she hasn't found the right guy, yet (however, she is not dating any guys). She wouldn't mind getting some sexual experience, but only with a guy who really knows how to fuck her well.
The sisters tell her that they know someone who would be perfect for her first time ... either they talk her into having sex with her Dad, or they blindfold her and tell her that she has to trust them. After the sex they will reveal who this super stud is, but not before .... or they show her the DVD so that the Tomboy can see how good Dad is ...
Mom finally comes home from the quarantine. Everyone was wrong, the virus was harmless. Since they have a very open relationship, Dad tells her, that he had wonderful sex. Mom asks him, if it was with Susan (the woman from the DVD) but he tells her: no, it was with our daughters. Mom is surprised, but she thinks it is very hot ... so she joins the family gang bang ...
