You forgot to take into account how Jyotsa still had lathered her booty cheeks with sunscreen, and because of how often she served and moved around it didn't take too long before her ass clapped your body multiple times and spits you out into the ground.

Luckily Jyotsa took notice of your absent, realizing her tiny passenger had gone out of her ass and turn back a little to see your tiny figure on the sand face flat as her big slippery butt threw you out. Unfortunately the way she puts you back in was less than gentle.

She 'accidentally' tripped herself, her large bearing ass smashing your poor body. The giant butt squash and flattens you, grind all ten tons of it's fat pinning and plastering their skin on you. When she looks back, she sees a poor tiny person, flatten like pancake on her big booty ass.

Whoops. Guess your dead now...
