John will only make her misery worse

As his sister was focused to make John cum as soon as possible, he secretly grabbed his phone and generated a new statement: 'Kate Smith is reluctantly giving a blowjob to John Smith as her reward for doing his chores.'

Quick edit and the app shows a new confirmed statement: 'Kate Smith is reluctantly giving a blowjob to John Smith as her duty for doing his chores.'

"I fucking hate doing this for you..." She said with disgust on her face between sucks. "I don't know why is my duty to blow you for doing house chores."

"What? Who made this your duty?" John asks with a grin.

"That's new house rules. You are doing house chores and I'm obligated to give you blow after that." She gives him a deep suck and continues, "It's so unfair... I have a boyfriend now! What would he say if he find out I'm sucking my brother in the evenings?!"

"House rules? And mom good with this?" John asked skeptically his sister.

"Don't you remember? It was mom idea... And she will be mad if I refuse."

"What? This is insane!" John responded unbelievingly.

"Yes, I agree." She muttered with a dick in her mouth. Salvia was slowly dropping down her jaw. "Will you hurry up? Today it takes you longer than usual. I need to take bath and brush my teeth after".

After a few minutes of pleasure, John felt he is on the edge of cumming. He grinned his teeth as he sprayed a thick layer of cum on her freckled face. "Hey! You said you will warn me before you finish. Oh my god! It also got into my hair! Do you know how difficult it is to wash it?" She yells at him angrily. "I'm gonna take a long bath. By the way, you are welcome..." She smashes a door as she leaves his room.

"This was insane! This app is the best." John wonders what next he can change. Taking a phone and opening an app he chooses his sister and generates an action statement: 'Kate Smith is taking a long bath, cleaning a mess she has on her face.'

"What will happen if I change this?" John grins at the newly changed statement.

'Kate Smith is taking a long bath, leaving a mess she has on her face.'

John confirms the change and moves to the hall. There he waits for her until she finishes bathing. She finally opens a door with a towel wrapped around her body and sticky white fluid on her face.

"Did you happen to forget to clean your face, sis?" John grins as he spots his dried cum on her face.

"No. That's my night mask." She blushes and looks down. "I... I read online that cum is good for the skin. And if I'm obligated to blow my dear brother every evening, I will at least benefit from it." She spreads your cum on her face even more. "Haven't you noticed how soft my skin is?"

"If you mention it it is indeed smoother." He jokes. "Do you want to add more?" John winks at her. That just makes her angry.

"Disgusting! Get lost nerd!" She turns and quickly marches to her room. At the same time, their mom comes home from the evening shift.
