how do you suck a cock for hours and not make it cum?

[Jericho]

When I want to delay orgasm, I think of my ex wife...naked and horny... and counting math problems using a loud voice..., as she comes towards me, wearing a strapon and a goofy smile.

some of the weird arse muthafukkers around here, that'd probably have the opposite effect!
In fact...........

Take some 3/8" rope and tie your balls off, tight. It will delay comming for quite some time.

First..teasingly run your tongue up and down her shaft...every few strokes, nibble and lick her balls and inner thighs. Keep that pace and every few minutes take her cock deep into your throat and let her fuck your face then back to licking and teasing her throbing shaft. Bring her to the edge then deep kiss her for a while while you leave her pulsing cock begging for your wet mouth.then make your way back down to her hot cock and start the process again. This should run her at least a half hour before she cums...

yeah sounds good man.

when i suck cock i do it assertively, i try my best goin down on a girl without coming off as the bitch

So you suck at sucking!
