As a heterosexual submissive woman, I obviously want to be good at giving blowjobs. And part of being good at blowjobs, obviously, is being able to deep throat without gagging too much. So today, I'm going to work on getting better at that. First of all, I'm going to try wearing my deep throat gag for 1 minute, to check that I'm still able to do that (I've not practiced in a while).  I manage that (I only start gagging really hard for the last couple of seconds) so I feel like I'm ready to move on to a more ambitious experiment. I've set up my fucking machine so that I can kneel with my back to the wall, and the dildo directed straight at my mouth. That way, when I turn it on, I won't be able to cheat by moving backwards.  I time myself for a minute, and turn the machine on. Immediately, I realise it's not going all the way to the back of my throat - it's lovely to suck on the dildo rhythmically thrusting into my mouth, but it's not challenging; I feel like I could do that for hours.  So once the minute's up, I move the machine closer, so that the dildo is in my mouth even at it's furthest point, and when the machine thrusts forwards, it'll definitely go down my throat.   I start again, and this time it's immeasurably harder.  I can't make it to a minute; I'm gagging on every single thrust, and gagging harder and harder each time. Even with the machine set to a slow speed, it's impossible to cope.  That can't be right, I must be better than that! I decide to practice my deep throating while the machine's not actually running, and though I still gag on the thick cock when it hits the back of my throat, I feel confident that I can improve upon my performance. Maybe speeding the machine up a bit will somehow help? I make another attempt, and gag even harder, over and over again, as the machine pounds the dildo down my throat. My eyes are watering & I'm scared I'm going to be sick, but it's very exciting nevertheless. Clearly, this is something I need more work on. Possibly, I need some kind of trainer, actually. But in the meantime, having been practicing one of my favourite things has made me want to carry on. Maybe I'm not perfect at deep throating yet, but I can certainly work on sucking the dildo, especially since it gives me so much pleasure!
