Kieran and Carolyn were friends for so long, the only problem was that she was a human. Kieran didn't care about that, they were inseparable. One day, they both made a pact to lose their virginity together, not liking the fact that they had to do it with strange people because they couldn't wait.
Breaking the friendship rule, they had sex, thinking that it would be a one time thing. They never expected for it to go on and on until they both started to get feelings for each other, and as always, the mate appears.
