Never On The Mouth
Cara and Ryan have been friends for almost a decade before they entered into an 'agreement', after Cara finally admitted that, after a heartbreak, she is not that adventurous when it comes to sex. Ryan is more than willing to be her sex coach, being the player that he is anyway.
Cara has one rule though, no kissing on the mouth.
However twisted their arrangement may be, they venture into a relationship that threatens to ruin their friendship, especially when that one rule becomes too hard to keep.
