"You want it? Earn it." (Taboo)

[Strangebuddy]

I've always thought it would be fun if after someone made a confession about their incestous attraction, the object of their obsession wouldn't be sickened, shocked, or delighted by it but rather be nonplussed and have some demands before they would consider it.

For example: Brother to sister.

The summer after college, bro moves back home and sees his baby sister looks absolutely amazing. She's fully grown into her curves and is confident as all hell. She's happy to see him and doesn't seem to mind him looking when she struts around in short shorts or a bikini. A few close moments, a little flirting, and bro is obsessed. So one day he confesses.

Sis pauses, rubs her chin and then asks, "So, where you taking me for our first date?"

Taken aback, brother asks what she means. So she breaks it down: he's kind of cute, honest, a college guy, has his own car, and being her brother would mean that she wouldn't have to introduce him to their parents but it's also going to make PDAs awkward. So she'll give him a shot to impress her but he's got to work his way up.

"Hey, you just admitted you wanted to fuck your sister, wouldn't have given Brad a shot if he had opened with that."

Or..."sorry, I don't date virgins, come back after you've gotten laid."

Son and mom

"Well, I do like younger men but I kind of like the idea of going to their house. Also, I like when they can treat me like a queen...how's the job hunt going?"

Essentially, it would be a story where the guy's lust isn't enough and he has to be a good boyfriend on top of everything else.

Similar: Smoking-hot older sister and/or young MILF mom tell nerdy pr0n-obsessed Sonny he can have the sex of his life if he'll straighten up and be a Man. Hit the gym; hit the books; drop the pr0n; join a service group; involve with the outside world, etc. They motivate him with incremental rewards as he improves and attains measured goals: flashes, touches, kisses, handjobs, and onward...

Flip genders. Sis is a shy, nerdy dumpling. Studly big bro taunts her to break free and release her inner butterfly. Are his pheromones sufficient motivation?

I really like that take. Maybe mom or sis catches him peeking on them or jerking off with a pair of their panties. They confront him about it and get him to admit what he did, maybe even get him to say something like they are the most beautiful women he knows. Right as he's thinking they're going to slap him or laugh at him, they shrug and tell him he has ten minutes to get dressed in some workout clothes to go jogging with them.

After about keeling over during the jog, mom or sis lays him down in the yard and take his shirt off, rubbing his chest as he catches his breath. When he has, they crawl on top of him, pressing themselves into him and letting him smell their sweaty body before planting a chaste kiss on his lips. They then crawl off and head off to shower, implying that when he can keep up with them, he can join them.

After he rests up, sis or mom ask if he really wants them, even more then any woman in the world. He nods and they then smile and head to his room and clean it out of all of his porn and then delete any saved videos off of his computer. They hold onto a few dvds though, saying that if he can go the week without watching any porn, they'll let him watch a scene with them sitting in his lap.

As for sis that could be interesting. Need a bit more time to think up a good plot for that.

Edit: sirhugs' twist might just work.

Sis peeks in on brother having sex with his girlfriend. She backs away at first but then stares as he pulls his full-sized cock out before impaling his girlfriend on it in a new position. At first horrified anyone could take such a huge tool inside of them, then fascinated to watch his girlfriend scream in pleasure and watch her normally laid back brother turn into an aggressive stud, she slips her hand into her shorts.

Girlfriend sees her and freaks out. Bro says some things he shouldn't and sis runs off to her room. Trying to make up, he comes in to talk to her. Sis is tearful so bro apologizes and tries to get the topic changed to something else. Sis however wants to talk about sex and how the heck her brother has been hiding such a huge cock. Bro does talk about it but tries to switch it to how sis got her expectations about sex.

Sis admits she got it from porn, manga, and games. Bro takes a look and sees she's got a lot of brother and daddy fetish materials. He asks her to stop reading that stuff and sis counters back she has no reason to. Maybe if he's offering something.

So bro calls her bluff. She ditches the porn and gets more social and confident and he'll help her get with any guy she wants. Sis goes wide eyed and agrees. She ditches the porn, cleans herself up and agrees to go with him to some parties, slowly overcoming her issues though bro helps by being very supportive.

So sis asks him after a month or two to hold up his end of things. Bro agrees and starts thinking of which of his friends would be best...when sis shakes her head and says since this whole thing started because of his cock (and she had to give up porn) she wants him. Bro is about to refuse but seeing his eager sister, thinking of all of the work she put in, and feeling his cock stir to life, bro agrees.
