Stuck with John

You place your hands on his tongue as he extends it. You lean on it as the giant teen sticks out his tongue. John draws his tongue in, pulling you into his mouth. The air is warm, wet, and smells like you would expect a teen boy's breath to smell in the morning. You lie on his tasting muscle. John lets it rest against the bottom of his maw, building up saliva. Without warning he presses you against the roof of his mouth, then moves you around on his tongue tasting you, and at the same time thoroughly soaking you in his sticky spit.
You are jostled around, suckled upon by the behemoth. You hear him laugh a bit.
His mouth then relaxes, "you want out?" John asks, throwing you about his dripping maw.
