I find the act immensely hot and most convenient. My partner is around 7 inches and I won't accept him finishing any other way. It sure is the most pleasant finish for your partner since it's a natural urge to want to have your cock deep buried (and still) when you unload and the most convenient for you if you don't particularly like the taste.
What strikes me is that when he cums I don't realize it from my throat but from the pulsating cock, which means that it's not exceptionally hard to take a deepthroat cumming (given that you can give a deepthroat pretty conveniently of course).
I am just curious how hard it is for you to do this (if you do), what are the feelings in case someone did this to you and why it's pretty rare to find guys able to do this, including performances like this in amateur porn videos.
