> [@Kai2090](#): > > I have an incredibly hot sister. She is now 18, and I am 21. I have a fraternal twin brother as well. Before I knew she was my sister I made out with her on a few different occasions. This was when I was like 17. She has grown into an incredibly sexy woman. And because I knew her before I found out, I am a man and she is a woman. She has an amazing curvy body, amazing ass and 38DD boobs. She blew me once when I was 19 if I can remember correctly. She also rode me on the couch during a christmas special. Sort of a christmas present. Wore a condom. No regrets. True story. What is an MTOS anyway? ---

And how did you then discover she was your sister? When she blew you when you were 19, did you know she was your sister (2 years ago)? Because you said you _made out with her_ before you knew she was your sister, and that that happened when you were 17. So two years later, when she gave you head, did you know it was head from sis? I’m not totally following the timeline here… ---

[![](https://img.youtube.com/vi/2mTGWPEysOY/maxresdefault.jpg "The Whitest Kids U´Know - Hot Sister") ](https://www.youtube.com/watch?v=2mTGWPEysOY) When my sister and I were teens, more than a couple of my friends told me my sister was way hot. I didn’t see it. ---

I’m not totally following the timeline here… Just a gut feeling but I’m betting she’s a step sister - probably attracted to her before the parents were. Talk about cock blocking though… ---

Wiki on the[the Westermarck effect](http://en.wikipedia.org/wiki/Westermarck_effect) > [@](#): > > The Westermarck effect, or reverse sexual imprinting, is a hypothetical psychological effect through which people who live in close domestic proximity during the first few years of their lives become desensitized to later sexual attraction. This phenomenon, one explanation for the incest taboo, was first hypothesized by Finnish anthropologist Edvard Westermarck in his book The History of Human Marriage (1891). Observations interpreted as evidence for the Westermarck effect have since been made in many places and cultures, including in the Israeli kibbutz system, and the Chinese Shim-pua marriage customs, as well as in biological-related families. > In the case of the Israeli kibbutzim (collective farms), children were reared somewhat communally in peer groups, based on age, not biological relation. A study of the marriage patterns of these children later in life revealed that out of the nearly 3,000 marriages that occurred across the kibbutz system, only fourteen were between children from the same peer group. Of those fourteen, none had been reared together during the first six years of life. This result suggests that the Westermarck effect operates during the period from birth to the age of six.[1] > When proximity during this critical period does not occur — for example, where a brother and sister are brought up separately, never meeting one another — they may find one another highly sexually attractive when they meet as adults, according to the hypothesis of genetic sexual attraction. This supports the theory that the populations exhibiting the Westermarck effect became predominant because of the deleterious effects of inbreeding on those that didn’t. ---
