Diff ppl diff taste diff requirements....
If you really know your body, you will know that cum shoots out due to the MUSCLE SPASMS, not from any sucking or vacuum caused by mouth..... so sucking harder to create a black hole vacuum DOESNT help you shoot any faster....
And your shiokness cums from the effect of all the muscles in your body SPASMS at the same time and period... nothing to do with the flow of cum out of your didi.... so sucking it harder also dont increase the intensity....
So by your very own preference, you will NOT enjoyz when u cum in miao miao... coz there is NO sucking or vacuum action there..... no...???
AND if the mouth is trained properly (NOT THOSE OUTSIDE WHORES.... niamah, must make me say this...

), they will know how to swallow the whole shaft, and seal it with the tongue and throat, so when u cum, the very feel of vacuum is there.....
So again, diff people diff requirements, your own preference doesnt mean its universally true either....
HSK out.... !!!
