although I kinda like the idea of banging Bacon's mom only being slightly let down by the fact its sloppy secounds since Bacon was there first, he better not be banging my mom or i want the option to use the scut bat on him where it truely hurts.what is this thing people have with sharing with their friends it makes no sence when it comes to friends you wan't a lift fine, you want company shopping fine, you want a loan to buy stuff fine, you want a hand moving furniture fine, you want to fuck one of my girls no fucking way, fuck off and go take a long run off a short pier. its bad enough he is trying to use me to clean up his shit that he caused with his timetraveling which he didn't tell me about untill he needed my help with it I might remind you. But you think its ok for him to shag my mom then what my sister, mygirlfriand or Gaz, ok maybe not Gaz since for the moment she's a prostitute even the old guy fucks her but at least if Becon did it would cost him. but as for the others hell no he may be my freind but if I have the option i'm cockblocking that fucker till he's old gray and his cock falls off. Like id want my mom after Bacon has been there in fact that would show a complete lack of taste on mom's part, Hmm actualy now i think about it im in two minds if id even do Bacon's mom knowing he's already been there (YUK).

I have to admit, your post is quite interesting - in psychological terms. The insight you gave me about yourself is: you don't trust your (best) friend or you just being selfish or narcissistic (pls don't take it personally! It is just, what I interpret from your post.).
My opinion is, that best friends have a deep connection / relationship to each other. If your best friend shares is girlfriend your his wife with you, it is considered a high honor with entire trust in you. Because he place himself next to you (same horizontal level) and not above (he is better than you) or under you (you are better than him).
I really don't know, if the majority just dislike Japanese-NTR (NTR for me: Nothing To Report -lol) or its a matter of age, culture/religion, country you live in, your sexual experience, etc.
It would be quite interesting to analyze, if people from the same area tend to the same sexual fantasies (e.g. like or dislike of NTR/Cuckold).
For someone who lived in China for a year, I encountered two situations in one, where the boyfriend or husband of the girl is ok with me (a white foreigner) to chat, dance and touch the girl (feeling up her ass) or to kiss her. Sometimes the girls boyfriend or husbands even invited me to a threesome (not always but 6 out of 10 times). And the other one, where the guy got angry (with a hint of jealousy) at the moment he saw me (before even talking to the girl).
From my companies "social and environmental guideline for foreigner employees", I knew that a high social status is very important for Chinese, and also for Korean and Japanese people. Thinking about it made me realize, why rich Chinese people (in my case) invited me to dinner with friends and family, paying the drinks in the club or buying (very expensive) cigarettes for me. Just that other people could see, that their pal is a (white) foreigner. So inviting me into their bed were less an act of humanity, but more a generous gift towards their girl/wife (you know for not leaving them for someone richer as them x'D) (keep in mind China has more males as females!). In the other hand destroying their social reputation/high social status by public humiliation is considered as a 'social-death sentence'. By knowing that, it becomes more clear, why Japanese like NTR-Stuff or other (female-) humiliation things (take a look into the Japanese society: facing rapid decline in birthrate, (super-) aged society, almost no female managers or company leaders, etc.). In a sort, the act of humiliation is a way of submission and a way to strengthen the bond of trust with the counterpart.
It also kind of schizophrenic for (US-) Americans for having the biggest porn industry in the world, but swearing on TV or public drinking is strictly forbidden, also banning public breastfeeding or nudity beaches (with exceptions for some US-States)....
Cheers!
