Sucking and Blowing with the Right Dildo Type

Hi everyone, I’ve been lurking for a while and now it’s time to ask my question… What kind of dildo works best for the Suck and Blow method? I looked around online for some time but didn’t find anything suitable. The holes in jelly ones are hard to make without ruining them, and drilling into an acrylic one doesn’t seem like a good idea either… Please help, I’m getting quite desperate:D Chosii
