I have never taken a cock in my mouth. But Have given deep throat, I love to hold it in deep and hard, have them looking into my eyes as I hold it there, when I feel the time is right pull out and watch gasps of air and then push deep in again.
TRUST is a big thing & it's why they look into my eyes at all times.

Looks like the poster choke and die on 7 to 8 inches of cock.

I'll share my technique.....
Laying on my back,my head tilting back over the edge of the bed....my throat naturally opens....to take a cock all the way. Popping the head into my throat quickly,eliminates a gag reflex....and men really like "face fucking". Just...work out the timing for catching a breath!. Susan

Practice makes perfect

I start off slow by licking and sucking the cock all over once I have a feel for it

After that I go all the way down and if I can’t touch the base just yet, I stick my tongue so I can. It motivates me to go down even further. Once it’s ready there I go for back and forth from head to base and when he’s ready to cum then I get closer to the base

I love sucking cocks but, sadly, have never been able to deep-throat. I must have the worst gag-reflex on the planet.
