If its your first time sucking dick or seriously fantasizing about a hard cock in your mouth, like any skill practice is everything. Id go for the most lifelike dildo you can find. Warm it up lube it up and start sucking. Get one long enough for deep throat at least 7” so it goes past the point of the most gag reflex. Take your time find out how far before your gag reflex kicks in but when you do commit to actually having the swollen head of a pulsing hard cock enter your throat go all the way quickly in one motion so your gag reflex doesn’t have a chance to react and don’t stop till your nose is touching his skin above the base of his cock and his balls are pressed firmly on your chin, or visa versa if your in a 69 position hold as long as you can then pull off equally as quickly. The goal is to be able to hold chinnuts deep while sticking you r tongue out to lick his ballls and swallowing at the same time. You can’t call yourself a cocksucker until you have balls pressed against your chin. Happy sucking The blow job king!
