slut on a leash
when a girl puts out and unleashes her wild side in bed with a guy, however, she will only do so when that guy is her boyfriend.
rob: dude, i always thought kelly was a prude?

joe: why do you think otherwise?

rob: mike* didn't tell you?

joe: tell me what?

rob: ever since he got serious dating that girl kelly, he said she hasn't been able to keep her hands off him and she does some wild shit in bed.

joe: haha! no way! that's what i call a slut on leash!

rob: slut on a leash? what's that?

joe: when a girl puts out and unleashes her wild side in bed with a guy, however, she will only do so when that guy is her boyfriend.

rob: well, at least that means there's hope to find a hot conservative girl who restores the confidence in us that there are no faithful women left in this crazy world full of sluts.

joe: you know what that means, she probably has friends who are just like that too!

rob: we gotta tell him to hook us up!

joe: hell yeah! i'll finally not have to worry about bringing a girl home. gettin some ass that has class!

rob: yeah buddy!

*mike: best friend of both rob and joe.
