Resting between opals breasts you wondered where you could go to explore her, You could walk around her mouth like it was a big wet cave, crawl through her trunk, walk in her ears, message her nipples, relax in her navel, rub your self against her crotch, explore her ass or look at her massive feet. All were interesting options but you couldn't decide.
As you sat in between opals breasts wondering where to explore, you began to feel her shift. Suddenly your larger than life lover was rolling over in her sleep. "mmmmm" she murmured in her sleep tossing her blanket aside and before rolling onto her side.

Her massive breast was pinning you against the other as she slumbered peacefully. Using some magic you gave yourself a strength, protection and respiration spell. Soon you climbed out from Opal's tits as she laid on her side. 
Your freedom was short lived as Opal rolled over again, this time on her stomach, her massive tit pinning you to the bed. You felt her massive nipple swell against you as you wiggled under it, Opal moaning in her sleep.
With your spells still in place your climbed out from under Opal. Once out from under her, again, Opal rolled back onto her back. 

"That was a close one" You said before feeling a sucking force. You were standing by Opals trunk as she suddenly sucked you into it.
You tumbled around the dark, damp snotty cave that was her trunk before Opal trumpeted you out. 

You then landed on the base of Opals bed before her feet, you approached them and gave them a rub, they were surprisingly soft and clean yet had a faint footy smell. You soon ventured between her massive thighs and approached her crotch. You began to climb up her panty clad crotch, only for her giant hand to trap you against it as she moaned more in her sleep. 
Opal began to pleasure herself in her sleep with you. As she continued you were surprised she hasn't awoken yet. 
Opal arched up as she continued, allowing you to slip down, however when she was done, Opal slammed her massive ass on you. Her butt was soft and weighty. You decided to stay under her for a bit, until Opal grunted a bit in her sleep. Suddenly you were hit with a big fishy scented fart. You heard your massive lover sigh in her sleep having farted on you. 

You then crawled out from under her, and climbed up onto her waist before reaching her mountain of a belly. it was soft and warm, much like the rest of Opal. You approached her naval, which looked like a deep hole. You leapt in, it was quite comfy and warm, food crumbs were found in her belly button. While there you realized you almost explored everywhere on Opal you thought of except for two areas. Climbing out of her belly button you used some flight magic and soared to Opals ear. You looked into the deep cavern and was careful and quiet as you climbed in. She kept her ears pretty well clean as there was little ear wax. 

You soon climbed out and arrived at her mouth. The massive cavern glistened in the night with opals saliva as she softly snored. You got in and looked around. It was amazing, you felt closer to opal, surrounded by her breath as you felt her breathing all around you. You soon climbed out and wondered what to do now.
