I did have a very hot experience with this once, I had never deep throated EVER, and was giving a BJ once, sitting up on the couch and the guy was standing over me, so my head was against the back of it, and he forced his cock down my throat as he was about to cum, I literally forgot I could breath out of my nose, panicked when I couldn't get any air, but he held it there, once I took a deep breath through my nose he stared coming and I relaxed and the light headedness, OMG!!! I was in heaven, literally floating as he slide it out and we lay relaxing, so yea its hot
