   Summary

   Being on a school trip without your boyfriend was bad, dealing with young teenagers for five days without Ryland cheering you up was worse. You couldn't wait for all of this to be over and fall into his arms.

   When you're back, you do exactly that, and pull your boyfriend into bed with you- or so you thought.

   ☆

   You realise a little too late that the man you are having sex with isn't the one you think he is
