"I should shove you up my ass, you little shit".

Cassie had said this once to you, in private, after you humiliated her by saying that her backside was blocking the view to the TV in a family reunion. She was only 15 at the time, and you were 12, so you didn't know better - she was insecure with her body's developments. The comment had greatly embarrassed her, but she held it all in and fake-laughed it off, only showing off her frustration after you met her alone in the kitchen.

Simply put the threat itself wouldn't be a problem, if it weren't for the fact that you were roughly the size of her thumb after catching the Shrinking Virus. You never uttered a comment about the threat because the very notion was embarrassing, and Cassie never demonstrated animosity towards you again, so the whole thing faded from your memory.

Fast forward, you completed your high-school studies. As a 16 years-old, you were still quite young but you could now begin studying at a College. Your choice institution was many kilometers away, and by law you couldn't live on your own, which means a responsible adult should take care of you. Luck would be on your side - Cassie was an adult now, and she lived right next to the college, so everything got arranged for you to live with her.

You said farewell to your parents for the moment, and Cassie closed the door of her apartment. You were standing in the palm of her hands.

"You can drop me anywhere, I can get around on my own" you said.

Then her grip changed to a constricting one, strongly grabbing your whole body. You quickly looked in shock at her.

"Oh I know, but I prepared your new accommodations very carefully, so why not get you there right away?" She responded. Her dark eyes looked eerily at you as she said that, and you didn't like that. She started walking and you saw the kitchen go by - previously you all had agreed you would live near the food for ease of navigation. You struggled against her hand but her dark skin didn't even move. Her grip was strong.

"Cassie, what are you doing?" You asked in fear. Her long dark hair swayed as she passed through a door, and you quickly noticed you were in a bedroom. Everything was neatly organized, with a computer desk, chair and a bed with two pillows visible to you. You heard her closing then locking the door behind her. She turned the light on.

"You know, I was really worried with you coming here to live with me" she said. Then, with you still on her hands, she grabbed the sides of her shorts and started stripping. The movements made you a little dizzy but after she readied herself you could see not only her shorts but also her panties on the ground, as she walked around her bed. "How would I take care of my little cousin? He's so small, the world is so dangerous" - she continued - "It would basically take all my time."

She started climbing the bed by all fours with you on her grip. Your world became a flurry of beds sheets, her green shirt and dark complexions of your cousin moving around. Everything finally stopped with her holding you with both hands near the headboard. She was apparently supporting her weight with her elbows and knees, because as you looked at her you could see her smiling face, her dark hair, and way behind her, a big naked butt swaying around.

"Then I had a little idea. Or, should I say, I remembered what I told you like four years ago." She licked her lips, then her head moved.

"Cassie WAIT DON-" was all you said before her mouth enveloped you. Her wet tongue sloppily went over and around you. You closed your eyes from the experience. She continued sucking and licking the top half of your captured body. The smell of mouth and saliva was strong. Then she started sucking.

"No no no she's going to swallow me alive and whole" you thought, a constant nightmare of victims of the Shrinking Virus. Your body was now entirely inside her mouth. You felt yourself moving towards her throat as her tongue maneuvered you inside her mouth. Her spit was all over you. Luckly, shrunken people hardly needed to breath and were quite resistant, otherwise you would be drowning. After minutes of being sloshed around inside your cousin's mouth, you got spat out into her hand, which quickly gripped you again.

"So here's the deal. You. Are going. Inside. My ass." Cassie said, and you heard her slapping her behind, which giggled.

"...what?" was your only reaction. Your mind was still on the threat of being devoured and digested inside her body so you didn't quite get what she had just said."

"Are you paying attention? I am going to shove you up my butt!" Cassie said, now more irritated with you.

"You... you can't! What will everyone think?" Was your only response. This was insane. You barely remember her threatening you with something like that years ago. Is she mad?

"Everyone will simply not know, because I swear if you ever tell anyone about what is about to happen I will come after you and do way worse, do you get it?" She was now smiling again.

"But why are you doing this to me? I never did anything to you!" You said. Why is she being so villainous? You don't remember any animosity between both of you.

"Of course you little shit don't remember, the axe forgets what the tree remembers." She then slowly licked your body again in a long, wet move. "Well, sucks to be you then, because for the future my hole will be your home." She then started moving you very slowly to her butt.

"People will ask where I am!" You said. Her other hand joined you near her backside. She then used both hands to pry open her massive butt. You could now see not only the engorged flesh of her pulsating, moist and shaved vulva but also a well-lubricated shiny asshole. The reality of the situation now came to you: She was really going to shove you up her ass. Or in this case, down, since she was pointing her butt upwards.

"Here is what I think of other people" she said, then you saw her asshole bulge forwards. A trumpeting hot fart escaped her anus, hitting you with an immediate strong smell, which lingered in the air as she slowly continued to bring you towards her winking hole. "I will just lie and smile while at the same time I feel you struggling there."

"I will die in there!" you continued. You continued to approach her quivering butthole. Seeing her sex and behind from this angle - especially considering she was clearly excited - turned you on too, but the feeling was in conflict with the immediate fear you felt in this moment. She was really going to do it, she was going to put you inside her body.

"Nah, you little shits are quite resistant. Which reminds me, remember to struggle and worship your new home. If you don't, I'll make your situation a whole lot worse!" Your cousin threatened once more. Her hand stopped right as you were to touch her asshole with your face.

You hung there, closing your eyes and trying to turn your face as her hole stood right next to it.

"Can you see it?" She asked.

"...What?" You answered. You didn't knew what to do. Her gigantic buttocks were wide open, glistering dark skin next to her lubricated anus mirrored your form.

"Can you see my hole? She asked.

"...Yes yes I can see it!" You answered to her.

"Complement it." She demanded from the other side of her body. You couldn't quite grasp the situation but angering her further wasn't on your agenda.

"It is... very pretty!" You said, frightened. Her hole was a terrible, pulsating creature ready to swallow you alive and whole, yet she wanted compliments.

"Does it smell? I bet it smells." She commented.

"It smells of strawberry!" You did the only thing you could and kept answering her demands.

"Strawberries, eh? Should be tasty. Lick it."

She quickly approached you a little more until you almost touched her asshole. In desperation, you started to push your tongue through her skin, which quivered. It didn't taste like strawberries at all - that was just the smell of the lube.

"I'm licking!" you said as you licked and licked the crevasses of the pulsating ring.

"I bet you wanna go inside to see what it is like." Tears almost appeared on your face but you held them in. You did not want to go inside her ass.

"Please don't!" Was the only thing you could yell to her.

"Yes." She said in a sultry tone.

"No!"

"Yes!" She said in a ultimatum, and you felt your head touch the center of her anus. Cassie moaned loudly when that happened, while you whimpered. It was happening.

She continued applying pressure, joining your spat-on form and her lubed-up back entrance. Pressure slowly made you advance effortlessly - she was taking her time. Your ears touched her flesh. The brown of her skin started giving way to a reddish flesh. You closed your mouth and eyes in a reflex, and the only thing you could feel was her heartbeat traveling all the way to you. She continued to move you more, slowly consuming your whole being with the most heinous part of her giantess body. As your insertion continued, you felt her winking hole help her by trying to drag you even deeper. Soon your shoulders hit her asshole, but the lubrication made the process way too easy - so now your whole torso was sliding to Cassie's insides.

"Hmmph. That's what you deserve." You heard her say. Her voice came from all around you. "You wanna live inside my ass, don't you?" she said. You continued sliding deeper and easily, and soon the only thing left outside her where your feet. All around you the pulsating flesh kept suckling on your body, while the repugnant smell of shit filled your senses. Your head passed through the most constricting part of the tube and was now on a more spacious area of her insides, while a strong muscle gripped the rest of your body.

"Heeeeelp!" you managed to yell, but the only feedback you got was a loud moan. The pressure and heat were tremendous, and you couldn't escape the womanly grip of her butt muscles. You started to hear a hissing sound - she was farting again, with you inside her ass. Hot fetid air traveled through and sightly opened her devouring aperture, illuminating your space. Her ass tunnel was yellowish, coated with a slimy substance that pooled around. You could see how the walls moved and pulsated, trying to gobble you up and drag you towards her core.

"Oh yes yes. You need to go deeper, to look deeper inside me." She said. You felt something strong touch your feet. It was a finger, which started pushing.

"Noooo!" you yelled again as you felt yourself sliding even deeper headfirst inside your cousin. Your whole body soon escaped into the more open space. Your arms were struck to your sides by hot female flesh, while her finger slowly pushed you even deeper.

"Yes, get in there. It is where you belong, you little shit." You heard her say. Her moans vibrated through her body with her heartbeat. Her finger could barely touch your soles, then you felt it retreat. You were now alone in her ass. "Enjoy your stay" was her final comment to you. Your orientation changed - she was standing up. Now you were lodged and stuck inside a girl.

Then she started clenching her muscles, smothering you with anal walls.
