IF you are fucking with a guy and you see that he will cum outside you. What do you do? Don't really matther where he cums or what way do you use to the guy really cum in your ass? Where does really value the cum? Only in ass or anywhere?

I use my legs to wrap around him or my hands to pull him close. Usually really sensitive uncut guys are the one who want to pull out but my quick body lock prevents them from pulling out as they inevitably up inside.  

Most of the time if I think they are getting close I'll tell them that when they get close to push in deep. A few guys that bred me asked where I wanted "it".  I've held on tight a few times, they got the message and gifted me..
