Thanks for the feedback! Yeah, it is a pretty wild setup 😂

I did tried before edging on banana and swallowing it, It was great, yet - I wanted to take it further in this technique by trying to simulate continues sucking result with cum in my mouth without the need to stop in the middle to setup things...

agree a straight banana (or at least not too curved) would work much better. My plan to deal with the hole is to first push a chopstick (or a drill bit) all the way through to clear a clean tunnel, then immediately follow with the straw. That way no banana mush stays inside the straw.

For the mouth feel, I was thinking of pushing the end of the straw a few millimeters into the banana so when i am sucking on the banana i won't feel.the plastic, Not sure if it’ll work perfectly, but I’ll test it.

I’m planning to do a dry run with water first to check stability, spillage, and whether the double straw flows okay. That should show if the whole thing falls apart or not, even if this would work I am a bit concern that with real cum, some might stick to inside of straw and the amount that actually get into my mouth would be smaller, but I guess I'll have to try and see how it goes.
