seems like u know ur shit.
I have a question (for research purposes). Is it better for two hands to cover the mouth or fingers inside the mouth (for research purposes).
Depends on how you want your oxygen levels to play out. Hands over would decrease oxygen and the top would need to be mindful of this. You can also slam forward while pulling back with more force, allowing for deeper penetration. Be aware of spine safety.
fingers in mouth would allow for full breath.
Very informative (for my research), thank you
Is a great position dont ask me how I know this
