Garganta profunda...quien me entrena?

Hello dear people...the topic is like this:

As many will know from my posts, I'm a very promiscuous guy of 41 years old.. tall.. athletic, very masculine... but loving a yummy hard cock... doesn't matter the size... just that it's clean and healthy...

I've had a PAPI for some time who knows how to attend to my desires of sucking... licking... kissing, enjoying his beautiful cock... savoring his great amount of semen... and making me feel like nobody!!!!

The topic is that I won't be able to see him again within 20 days, and he asked me to practice because he wants me to make a deep throat... and get my mouth.

I'm excited about the idea!!!!
I've already done it several times with my tongue passage, savoring his testicles full of cum.... but now he's going for more!!! He wants me to take him in my mouth like in pornos!!! So I have to train to satisfy him as a good submissive promiscuous that I am!!!

But the topic is that my vibrator is 21x6... and while I can try the depth, it's very wide and doesn't let me breathe well....

That's why I'm making this post, to see if there's a charitable soul who is willing to let me practice... so I can attend to my man as he deserves!!!!
If I can learn well... he'll let my assistant participate in a sex session with us three... obviously... two dildos for me... and if I do it well... they can enjoy my Booty... the two of them... as many times as they want!!!!

But I need that... A PROFE!!!!!... someone who will let me develop the capacity to be a petero in all its letters!!!!
Will there be that man here on Poringa?????
