For her to do a favor for a friend.

"In that case I want you to do a favor for one of my friends," you said as she sucked your cock in her mouth.

"What kind of favor?" Carrie asked as she pulled her mouth away from your hardened dick.

"Well I have this friend from school named Timothy Woods but we always called him Tim for short," you said rambling.

"Anyway Tim's got a new job heading up a local psych ward and he looking for someone to go undercover as a patient so he can get an idea of what things need improving," You said as you waited to see how Carrie would react.

"And you thought of me?" Carrie asked with a tone of confusion.

"Well I had thought of doing it myself but Tim is looking for someone that can't be traced back to him," you said trying to reassure Carrie.

"Think of it as role-play you go in under a fake name and spend a couple of days then report back to Tim," you said trying to entice your girlfriend.

"When you put it like that it does sound kind of hot," Carrie said as she bent her head down and started to lick your body.

"I'll even come and visit you well you're there but I'll have to do it under an assumed name," you said as Carrie moved across your naked body.

"Maybe you could even wear a disguise," Carrie said moving her tongue across your neck.

"I could wear a fake mustache," You said laughing.

"Or a beard," Carrie said laughing as well.

"So is it a yes?" You asked as Carrie grabbed your dick once more.
