Head to the library

Isaac was horny, but he wanted to save his cum for Dr. Patel. He headed to the library to see if he could have some fun there.

The first thing he noticed was three coeds chatting and laughing while studying.

He walked over to them and took out his pendant. "Excuse me, ladies, could you tell me what you think of this?"

A few moments later, they were in a trance. Isaac sat down. "You believe whatever I say without question. You will do whatever I say without question. You trust me completely. You will gladly ask any questions I ask you."

Isaac snapped them out of their trance.

"So, ladies, I'm a study coach. The university has me give out free study and relationship advice. What are you names?"

The brunette was Sarah. The blonde was Mindy, and the auburn-haired girl was Melanie.

"Tell me, do you have a boyfriend?"

Sarah and Melanie did.

"How often do you have sex?"

Sarah said about once a week, and Melanie said twice a week.

"Ladies, at least once a week suck your boyfriend's cock and have him cum on your face at least twice a month. Have him spank you and fuck you from behind once a week. You should do that to be a good girlfriend, and Mindy, don't worry about having a boyfriend until after you graduate. In the meantime, enjoy being single and sucking lots of cock."

The girls all agreed.

"Now I have a great way for you to focus while you study. Each of you, right here, take off your panties as quickly as possible."

The girls looked embarrassed, but each took off her jeans and panties as fast as they could before putting their jeans back on.

"Great, now exchange panties."

Sarah handed her panties to Mindy, who handed her panties to Melanie, who gave her panties to Sarah.

"Wad those up and put them in your mouths. Chewing on a pair of panties that another girl just removed will really help you focus."

The girls just nodded along. They wadded up the panties and shoved them into their mouths and started chewing on them.

"When you are finished studying, take the panties out of your mouth then hand them back. Put them back on. You three should meet as much as possible to study. After you finish studying, send more oxygen to your brains by french kissing each other as you massage each other's breasts. Spend at least one minute frenching and massaging tits with each of your friends, and it's perfectly fine to do it in public. Finally, at least once a week ,the three of you should get together and sleep nude in the same bad while you spoon."

The girls could not speak as they were chewing on each other's panties. "No need to thank me." Isaac got up and looked for more fun to be had.

He spotted two attractive girls sitting at a table near a nerdy red-headed boy. The boy would sneak glances at the girls who seemed to be ignoring him.

Isaac wondered if he should have fun with them.
