Well, my experience is as her throat spasms due to the gag you get an awesome soft clamp like feeling on the part of you thats in her throat, deeper the better, of course most of whats here are theatrics. But if you got a gal who will throat, she most certainly will gag at some point, try it, trust me you will enjoy it.
She can't deepthroat easly but he tries
n she sucks it!
