Next morning

John knew that her anus was very tight for his dick. And if he wants to take her from behind soon he needs to speed things up. With an app, he generates an appearance statement many times until he's presented with a sentence: 'Kate Smith asshole is a virgin and very tight.'

He thinks for a second. He can change a virgin state but that would mess whole 'brother defloration' in the future. The only word that makes sense to change is tight. He swaps a word and confirms a new statement: 'Kate Smith asshole is a virgin and very expandable.'

John slept that night very well. Early in the morning, he was thinking about how his sister offered her virgin anus to him. It was so surreal! She was sticking fingers into her anus just to be prepared for your penetration. And all of this while she called her boyfriend Eric.

John get up from bed, changed into school clothes and after he was done with the morning hygiene routine he went down to the kitchen.

"Good morning, John. Breakfast will be ready soon." He saw his mom preparing vegetables. He hated his mom's healthy breakfast. She was holding a diet and she insisted John and Kate do the same. It's for health benefits. He quickly unlocked a phone under the table and generated an action statement for his mom and edit it to 'Elisabeth Smith is preparing pancakes for breakfast.' And when he looked back she was indeed preparing pancakes.

His mom put down a place full of sweet pancakes, just like John loves them. Before he had a chance to take a bit, his petite sister entered the room.

"Wow, sis. You look... beautiful in that dress." Commented John her skimpy minidress with a red flowered pattern. She doesn't say anything. Only what she does is a spiral that uplifts her dress. He spots just black almost see-through panties. Then she leans forward on a kitchen island and places her hand on a dress. She uplifts her dress to present John her almost bare ass. She wears black lace panties under them she has... wait for it... large pink buttplug! When she catches him looking down there she responds with a wink.

'Oh my... It will be fun.' Think John her hole will soon be his. His sister slowly sits down on a chair with a quiet moan. This thing is so much bigger than my dick. 'She will be perfectly stretched for me if she wears it the whole day'.

After she finishes eating pancakes, she gets up and announces. "Eric will be there soon. See you mom." She turns and leaves. When she is at the door, she gives you one last sight at her plugged anus and leaves the house.
