I guess it's only fair to share the other end of the spectrum as well
The more bold folks who know exactly what they desire, gently propping open our maw to get better equated with it, enjoying the subtle tastes as they make use of the cavernous space and climb inside.
The simple bliss as they decide to make it much more secretive as they close our maw soon after, enveloping them in a soothing pink glow as they gently grind and tease against the sensitive synthetic flesh surrounding them as it eagerly starts to coat them in our biogel.
Hearing the slowly building huffs and moans once they start to get into a rhythm, the biogel only there to enhance their pleasure while they grow more and more emboldened as our synthetic flesh teases against them and molds to their desires.
Until finally we get rewarded with their well earned climaxes, tasting every little flavor and note possible as we work to tenderly milk out every last drop as much as we can~
Some folks finish here and carefully slip back out, fine but thoroughly coated in slick fluids where they say or layed, but some folks are far more eager to enjoy much more.
They tend to linger and decide after a moment that they can't resist, and proceed to enjoy themselves further, spending hours milking themselves dry until exhaustion which leads to our favorite part~
Once they collapse against our "tongue" and let us take over fully, gently kneading and squeezing around them as we take note of them before carefully guiding them back down our "throat", a tunnel of slick, kneading walls that ensure comfort and pleasure as they enjoy the trip down all the while making sure to savour their taste all the way down~
Nothing to worry about though the first timers obviously panic at first, which shamefully makes our senses go wildly as they squirm and struggle inside until the biogel coaxes them into relaxing but there's still plenty who keep up that desperate struggle, making us practically melt as we're overwhelmed with their efforts before they're quickly slipped through our drenched tunnel.
Completely safe albeit heavily drenched in sweet smelling biogel and their own climaxes if they had anything left after being so thoroughly kneaded and caressed inside us~
