Conditioned Response

Great story! Please write more chapters and keep up the realism. It deserves a sequel, but the story should not be ruined with the sex involving other family members or any third party. It damages the realism. The charm here is the secretive nature of their relationship and how it started innocently enough and developed to a secret crescendo. After Todd's discovery, at some point, the conditioning "magic words 'So Good'" may no longer be needed. Maddie will initiate and seize opportunity to locate Todd wherever he is in the house and, actively, even without asking, start sucking his dick. Better, too, if at times Todd is engrossed in something else and completely oblivious until his cock is already in Maddie's hungry mouth.

Maddie is not completely innocent in this story by initially spying on her brother and Jasmine. Therefore, she happenstance-opened this rabbit hole herself. Her attitude further warms to Todd after he stood up for her eye surgeries. Maybe she has an additional unconscious desire to do something for him and her inability to do so increases her compliance. Without glasses, Maddie begins dressing more provocatively, lets her hair down, and obsessively expands her BJ skills all to subconsciously capture Todd's attentions. Maddie has set her sights on capturing Todd so she can satisfy her oral cravings and perhaps obtain his exclusivity. This changes the way Todd sees Maddie and foments his inappropriate thoughts about her. Soon she can't contain her joy when he arrives home and gets clingy dressing even more scantily. How could an eighteen-year-old Todd resist such a situation already underway? His heightened curiosity got the best of him and when he saw that his suspicions were true it was too late! Therefore, especially initially, Todd would explore Maddie's willingness for acts he either hadn't experienced yet or couldn't acquire from girls like Jasmine. Therefore, an emboldened Todd might tempt Maddie's backdoor under such situation.

For readers not wanting a straight BJ to anal story, recall that Maddie is HIGHLY INTELLIGENT. Maddie would understand the risks of an incestuous pregnancy and research it in depth too. She would analyze and plan the best ways to remain undiscovered and would instill such ideas in Todd also. Maddie has no desire to stop and, considering Maddie's urgent oral fixation, neither does he! She could not trust Todd to pull out or use condoms reliably. Does Todd even have a job? Does Maddie, other than college? How do they hide the evidence? Maddie through her intelligence would eventually try anal sex as a preventative measure.

I prefer that Maddie initially resist anal until her own desires for penetrative sex overcome her emotional resistance and reason. Perhaps she surrenders panting to Todd, "Oh, it feels good. Oh, 'so good... so good'." Then her mental switch flips and she pants, "Take me! Take me now before I change my mind." Initially not wanting anal, Maddie must be a naive, uneducated novice regarding anal, only learning through nervous, physical experiences. This ultimately establishes Maddie as the "eternal virgin", an angle which has not been explored on Literotica much, if at all. After the initial pain and Maddie begins finding pleasure in the backdoor penetration, Todd demands Maddie admit her pleasure. Maddie does so saying, "Oh, it feels good. I feels really good. Oh, so good." repeating "So Good", which reintroduces the conditioning aspect as an afterthought. This may allow Maddie to achieve orgasm anally. It also reduces her hibitions against the use of her backdoor. Additionally, how about some different sex positions, like over the couch's cushioned arm or back, standing up, or leaning or pressing Maddie against a wall. It seems Literotica has overdone the bed and bedroom angles, so breathe some spontaneity into the sex. And, obviously, Todd must return the oral treatment!

Perhaps without seeking romance elsewhere, they focus on all of their shared secret pleasures, which leads to them acquiring high educations and seclusive jobs. Meeting their own needs and not wanting marriage or children, they could live secluded together happily ever after.

Excellent pacing and development till the end where it cuts off a bit abruptly. It could have gone into him orally paying back his sis the way he used to for Jasmine and blowing her mind, really cementing their new relationship and making her anal training much easier. Great sequel or two (three?) possibilities. I also question where he finds her naked and asleep under a sheet and instantaneous goes from loving, protective brother to opportunistic rapist without any mental turmoil. Great for the sex scene, betrays the quality writing in the rest of the story.

Where's the follow up anal story?

This story needs a sequel where Todd trains her ass. This is easily my most read story on this sight and I always come to check for s sequel.

Out of all the stories I've read here, this is the only one I want to see a sequel to. Please, for the good of humanity, let us see a sequel to this work of art.
