Screw with her a while.

"I swear, Mel, you are the rudest person I've ever met. If I tell anyone, you'll have no friends."

"Oh my god! What did I do now?"

"I graciously allowed you to suck my cock and swallow my seed, which you found very tasty, and you don't clean my room in exchange?!"

"Oh god, I'm so sorry."

"And you don't call me 'sir!' Whats' wrong with you?"

"I'm so sorry, sir," said a frantic Melissa. "I'll get started right away.

Tom's room was a mess, dirty clothes littered the floor as he was due for a laundry day. Melissa started picking up his dirty clothes.

Tom started filming the naked girl with his phone. "I'm doing a documentary on manners, so it's OK if I film you."

"Oh, no problem, sir."

Tom smiled. He had a hot girl who would believe anything no matter how ridiculous, so he decided to really push it.

"Wow, it's obvious you are turned on by the smell of my dirty socks and underwear."

Melissa looked at Tom, blushed then looked at the dirty socks in her hand.

"It's OK, you can sniff them all you like. Take a deep breath if you like. I won't tell anyone."

Melissa brought the socks up to her face and inhaled deeply.

"Damn, the smell of dirty socks and underwear make you horny. That's OK, but you really should tell all of your closest friends, heck even share the info with your classmates while you wait for class to start. They would find it interesting, and more of them would want to be your friend."

Melissa took another deep inhale of Tom's socks.

Tom watched Melissa grow flushed. He could not believe his luck and how funny this was. He also knew in a few minutes, he'd be ready for another fuck or suck.
