You may not ever get tired of watching it but you would get tired of doing it. Mostly Japanese women only know how to respond to sex in a rape / molest type fashion. Ever wonder why 90% of all Japanese porn is of the male "taking it". It gets boring after awhile to actually have to do it that way every time. It feels like you are molesting a 10 year old girl. Fine if you are an 18yo virgin but not cool if your 40 and had sex a million times.
I was told years ago, be careful how I use the words "never, forever, or always". But in truth, I WILL NEVER get tired of seeing Asian Girls GET NAILED. It is ecstasy ... just watch and listen ........
