Looking for a female to try this with

So, I've made it no mystery I don't generally post in the forums and prefer to stick to Ecchitexts.  However, there's an idea I've been trying to get off the ground but hasn't exactly panned out yet.  It's kind of a different take on an idea I've tried quite a few times with others, and a lot of the time, this has gone fairly well. (Also, while this description is a little lengthy, try to pay attention to every detail.  I've had partners miss a few of the details I mention in the past)

The basic premise is a unique one.  Basically, a teenaged girl's parents have died recently, but in their will, they requested that the son of a family friend be adopted as her older brother to keep her company and look after her.  However, the girl herself has an unbelievably foul temper and will lash out physically at anyone who does anything to piss her off. (Think your typical tsundere) However, the boy could probably avoid angering her if not for another problem.  It seems the trauma of losing her folks has caused her to develop another personality that she is completely unaware of, this one constantly horny and wanting to get with any cute guy she sees.  To make matters worse, said personality comes and goes at random, meaning there is no telling when it will show up and most likely ruin any progress the guy makes with her normal side.  So a typical scenario would involve the boy and her normal side being in an area together only for her horny side to take over and force the guy to violate her, and the more he resists, the more she likes it.  Then just as things are getting really steamy, her normal side returns, immediately gets the wrong idea and sends the guy packing.  Could it be possible that overtime, the two can develop a genuine bond, or would the guy be better off bailing on her?

A few things worth note if you haven't seen my preferences, I don't always write long posts.  I can usually avoid over-reliance on one-liners, but don't be surprised if you get less than five sentences in a post.  Another thing, because I've had partners guilty of this in the past, don't be afraid to go all the way with the tsundere personality.  I've had partners who seem afraid to hurt my main lead too much in the fear that I won't like it, but I'm looking for someone willing to go all-out with that. (Same with the forced violations.  Seriously, do not hold back) Anyway, if this sounds appealing to you, send me a text and we can discuss details.
