Giantess Unaware - Babysitter

"I'm too old for a babysitter" you argued as your parents dismissed your demands and continued getting ready for a big night out.
"You remember what happened last time," Your Mother tells you " We can't trust you home alone"

Angrily you storm off into the den and slam the door behind you. You sit on the chair and pull up your phone to complain to your friend about how unfair this whole thing is but before you can type a single letter you're hit with a sudden headache and your vision goes blurry. You wake up moments later shrunk and alone on the chair. You look down to see your phone fell to the floor when you shrank and figure it might be a good plan to use the phone to get help when suddenly the door slides open and 2 massive legs wrapped in denim walk in. You are looking at a massive giantess that you don't recognize, she's so hot!

"I'm here to babysit you, we're gonna have a great ti.." She cuts her sentence off as she realizes you're not in here. She turns to leave but notices your phone and walks right over to your chair and stands infront of you. Before you are 2 massive buttcheeks covered in jeans so tight they look like the fabric could rip at any moment but to your amazement you watched as the babysitter bent over in front of you to pick up the cell phone on the floor, stretching the jeans even further around her deep butt.
"No! I need that!" You yell but she just stands up, completely unaware of your words.

You watch her shift her weight from side to side for a few moments before her ass begins to bend and descend towards you.
"I'll just wait for him here" she says to herself as her ass hovers above you and gently drops. Lucky for you she sat at a side angle so to not crush you immediately but that moment was quickly coming to an end as she adjusted in her seat, covering you and smothering you.

The weight of her ass cheek pressed down on you but the extra fat of her butt combined with the soft seat beneath you saved you from being flattened. This, unfortunately, was not much of a consolation as you quickly realize you can't move and you can't breathe.

You try squirming but can't move a single muscle as your body is pinned in place. You try to breathe but her butt covers your mouth and her weight is pressing on your chest too hard to expand your lungs. You try biting her and this seems to have gotten her attention but she must have thought it was an itch because her only response was pushing her butt cheek deeper into the seat and rubbing it against the chair. This was too much for you as you felt bones snap. You try to scream in pain but nothing comes out because of this giantess ass smothering your face. You give one more attempt to scream but to no avail. You pass out from asphyxiation as she continues to sit patiently waiting for you.

She would find you later that evening but it was too late, you were already dead. The babysitter flushed your lifeless body down the toilette and told your parents that you ran away. Nobody would ever know what really happened to you that day.
