Install hidden cameras.

After Kevin had a few minutes to recover his mother came back downstairs.

"Right, you've now had enough time to recover" She stated "Let's get to work. Now I have $150 dollars here, I want you to use this money to buy 4 hidden cameras and return the leftover money. Once you have obtained the hidden cameras with WiFi transmitters, I want you to set them two of them up in your sister's bedroom while she's out with friends, and also set the other two in your bathroom. I then want to see you wank over the footage by the end of tomorrow. Am I clear?"

He still couldn't believe what his mom asked him to do. But after taking a moment to compose himself, he agreed. "I'll do it". But then a thought went into his head. "Should I buy some more for your bedroom and en suite?"

"My my!" beamed his mother "What a thoughtful young man? Yes, I shall double your amount to $300 dollars. Don't delay young man." He didn't even dream of refusing this order so he got on it right away

The drive to the shop was uneventful, as was the shopping trip itself. He wondered if the cute checkout girl had any idea what devious things he was planning on doing with them. If she did know, would she view it as a good thing that he was doing his... Chores? Yes "Chores".

When he got home with the cameras, he immediately showed them to his mother. Much to his relief, she concurred that they were good quality. He quickly handed over the receipts and the $35.92 leftover. Now all he had to do was set them up. He could do the bathroom ones immediately. Still, it was gonna be a few hours before his sister left so he had some time to kill. "MOM! ne called. "ANYTHING YOU WANT ME TO DO NOW?"

"I SET UP A TO DO LIST FOR YOU TO CHECK!" She called back. "I'VE ADDED YOU TO A NEW LIST, YOU SHOULD BE ABLE TO FIND IT."

Sure enough, he could find it. And one of them immediately struck him as very doable (or fun)
