Etsuko was so lost in her happy blissful world, she had no idea what was coming. You heard the rumbling and felt the small vibrations in her flesh enough that you got a bad feeling about what was to come, but no matter how hard you fought or clawed, the entrance you came in through was sealed tightly shut.

The young sumo moaned happily before she was caught by surprise by a massive blast from deep within her bowels. You were closer than point blank this time and took the full onslaught of her fart, passing out from the stench immediately. It did have one upside though, as the entrance to her backdoor opened to let out the gas you were blasted out with it! Your unconscious body slammed into the fabric of her makeshift bikini.

Etsuko's eyes shot wide open as she realized what she had done. She felt your limp body against her flesh and rushed to retrieve you, holding you in the palm of her hand and praying you were alive. Relief rushed through her as she saw you taking slow, deep breaths.

"He is resilient, but that would have been a lot even for the greatest champions of all time," she giggled to herself.

She sat and waited patiently until you woke up. After a few quick coughs, you blinked blinded by seeing the light outside of her cavernous ass for the first time in what seemed like an eternity. She looked down on you with a tender smile.

"Well hello my little disciple," Etsuko said gently. "I'm sorry about that, your games and little massage were a bit too wonderful and I lost myself. I assure you it was unintentional, but I hope after your nap you feel rested?" she asked, looking down at you earnestly.

You wanted to scream at her. You wanted to tell her off. You wanted to ask her why the hell she didn't pull you out of her ass or why she'd keep you trapped there. You wanted to make sure she knew you didn't enjoy a second of it. But as you looked into her deep brown eyes, her gentle face despite the powerful frame she carried, all you could manage to do was smile and nod.

She smiled back at you happily.

"That's good! Now, we have some specific training instructions from our master, and our first step will be to make sure you are thoroughly familiar with your instructor. Are you ready?" she asked.

Before you could respond, Etsuko....
