sister gives blowjob to brother, because she is short on time.

What about this one:

There is this family of 3: Mother, daughter, son

The son had an accident and both hands are broken or at least hurt so he wears a plaster cast or bandage. He can't really use them. Right now, he is totally limited. Mom needs to feed him and also needs to help him go to the toilet. She opens his pants, pulls his dick out ... you know what I mean. It's no big problem for them. Sure in the beginning it was strange, but then - when he was a baby, Mom always changed his diapers, so there is nothing new for her. And it is similar for the boy - he doesn't think about his mother in an erotic way.

Well, one day they are in a shopping mall. They decide to divide, so Mom goes off to shop for clothes, while the siblings head over to a CD store. However, shortly before, they had lunch and the guy drank a lot. Now he needs to pee really badly but his Mom is not near. So he has to ask his sister to help him - open his pants, pull his dick out ... she is kinda worried and unsure, but she also knows that he really drank a lot and so she wants to help him get relief. They find a small restroom and sneak in restroom (I think one for females), so the boy has to sneak in without being seen.
So now they are in the cabin. Brother tells her what to do: opens his tight jeans, pull the underpants down, that's all. Maybe it is the first time that she sees a real dick, who knows. She does as told by her brother. When she pulls his underwear down, he can take a good look into her cleavage. She has nice big boobs and since it is a hot summer day, she doesn't wear bra, the brother notices. He can look right at her boobs. Now sister turns around, while the brother pees. Since he is sitting on the toilet, he can do it alone. However, when he is finished, he also needs assistance. He tells her to grab some toilet paper and wipe his dick dry. While she bows forward, he looks into her cleavage - that, and her hands on his dick give him an erection.

Sister becomes embarrassed and stops. She wants to pull his pants back on, but since his jeans are so tight, she can't do it as long as he still has an erection. She tells him to think about something unerotic, but he can only think about her boobs and her hands on his dick.

Maybe they are running out of time (maybe the shop she wants to visit closes soon) so the brother gives her the advice: the easiest way to get rid of an erection is to make him cum. At first she is reluctant, but she is really running out of time (maybe it is the last day of a special offer like: the new ipod for only $50, if you buy between 2 pm and 3 pm, and right now it is already 2.45. So she starts to wank his dick. But then the brother says: if you really want to make it fast, what about this: show me your boobs - and then, don't use your hands, use your mouth. She is kinda shocked, but then again, she can save a lot of money. Sure, she could also run out and leave her brother. But first of all, this is the ladies restroom, and a guy alone in a ladies restroom ? Also, she doesn't want to leave him alone. And maybe he is the one with the purse ....

So she gives in, pulls her shirt up and starts to give him a blowjob, until he comes ....

I know, I am replying to myself ...

but while I was away, I had another interesting twist for the story idea:

As I said, they are in a ladys restroom. Well, as I said, the mother is also shopping, but after some time, she also needs to go to a restroom. And by a coincidence she visits the same restroom as her kids. They are so focused on the blowjob, that they don't notice that they are no longer alone.

The mom hears that something is going on in the neighbor booth. She hears a guy moaning. The wood wall between the cabins doesn't go down to the bottom, there is a gap to the bottom of about 5 to 10 inches. So she can see the feet of 2 persons. One person is kneeing in front of the other. It's obvious a girl, judging by the fancy looking shoes. Somehow, they look familiar to her, but she is not sure where she has seen them. From the position and the sound, it is very obvious that a guy receives a blowjob. Just when she wants to leave the restroom she even hears how the guy whispers: "now swallow my cum"

She becomes really curious, so after she left the restroom, she hides behind a column and watches the restroom door. Since there was no one else in the restroom, the persons that come out next have to be the horny couple. But what a shock - the first person to leave the restroom is her own daughter. This can't be true. Her daughter is doing a blowjob in a restroom, like a cheap whore ? She looks down at the shoes of her daughter - and yes they are the exact the same like the ones she just saw in the neighbor booth. But how could that be ? Her daughter is single.
The mother sees how the girl is looking around then she tells the guy to come out - and now the mom is even more shocked. It is her own son. And when she sees his horny smile, she knows she can't deny it - her daughter just gave her brother a blowjob in a restroom ...
