Be completely honest with myself

Looking at my new impressive and mildly frightening erection, I'm suddenly glaringly aware of what got me hard.

I want to fuck my little sister. The thought comes with a small pang of guilt. I've fantasized about my little sister tons of times, but those were just fantasies. There was never an actual possibility of it happening. I told myself that I would never let it go past the odd fantasy. I would never be the awkward brother perving on his sister. I would never do anything that would make my sister feel uncomfortable around me. I just couldn't. After all I never want to hurt my little sister. I love her way too much to ever do anything that would hurt her. But I need to be honest with myself. If this is real, and judging by the size of the erection in my hand it certainly is. Then it's only a matter of when, not if, I fuck my sister.

I look back up and the screen, for a long moment I just sit there letting this all sink in.

Finally I take a deep breath, and start to work it out. If I'm going to do this, and well...I am. I need to do it right, or at least as right as altering reality to get my little sister to fuck me can be. I need to make sure that whatever happens I don't loose her. That we don't loose us. After thinking for a long time I finally start to write.

[My little sister is in love with me, and has been for as long as she's understood the difference between loving your brother, and romantic love. She finds me highly attractive, and physically stimulating. Interacting with me in any positive way is sexually arousing to her in direct proportion to how positive the interaction is otherwise. Thinking about me, or being with me in a sexual context is and always will be incredibly sexually arousing for her. I am the only person that my little sister has fantasized about sexually, and the only person that she has ever imagined being married to. Initially my sister would feel guilt for fantasizing about me, knowing that **** is wrong. She did her best to repress her desires and not act on them even in private. However eventually she made peace with her desire, and in the last year learned to accept it. Spending so much time repressing her love of, and attraction to me has left it's mark in. Increasing the urgency and frequency of her thoughts of me, now that she has accepted what she wants and desires, and makes her perpetually at least mildly aroused for me, even when fully satisfied. Since accepting her forbidden love and desire in her heart, my little sister has masturbated while thinking about me on average 12 times a day, at least 3 of which on average are to full climax. The only reason she has yet to approach me about her love and desire, is fear that I would reject her, and her incestuous nature would ruin our relationship. If she ever thinks that I feel the same about her, she will throw caution to the wind and take her chance at true happiness by propositioning me. She will not be indirect about her desire, and will bluntly ask for what she wants. If we become sexually involved, she will always be blunt, honest, and straight forward with me when asking for her desires]

[My little sisters vagina and anus are on average twice as sensitive to penetrative sex as the average woman, and she can achieve orgasm just as easily from penetration of either or vagina or anus as she can from clitoral stimulation. Both her vagina and anus are extremely tight, but also extremely elastic, allowing them to maintain maximum tightness when stretched, as well as allowing them to return to their original state regardless of how stretched they become. She derives intense sexual pleasure from the sensation of her vagina and anus being stretched, which is magnified when it's being stretched by my erect cock. She derives significant sexual pleasure from the pain of her vagina or anus being stretched due to the stretching being sudden, significant, or violent in nature. She has incredible control of her vaginal muscles, and loves to squeeze them tightly around the full length of anything inside her. She finds the act of learning to use, as well as actually using her vaginal muscles to better sexual stimulate the entire length of her partner to be a fun and challenging activity, as well as a magnifier to the pleasure she gets from penetration, the level of magnification of her please directly correlates to the amount of effort she puts into pleasuring her partner, as well as the perceived level of pleasure her efforts grant.]

Taking a shaky breath to steady my nerves, I stare at the two new alterations I just made.

"There I did it." I think.

Now I just need to show my little sister that I find her romantically appealing, and sexually attractive.
