You see a giant mouth bend down to where you are, and a huge tongue dart out and start licking.
"Oh gross...," you say to yourself, and move back. You do NOT want to get caught by that thing. Now, if you were normal sized and watching it from the outside, this all would be very, very hot. But considering your situation...yeah, it's gross and a bit scary. But the walls are reacting to Emily going down on Beth, and you get thrusted towards the entrance, where Emily's tongue is moving around. What happens?
