I'm so mad at klaus , we've been fighting nonstop. He's jellous of how close I am to Steffan. He's hot, and single, I am atracted to,him. I go to the Salvatores elena hugs me. I say " he's being so immature with not trusting me with steffan". Later steffan goes into his room which im sleeping In and says " im sorry , I didn't mean to come between you two, if he is jellous then we shouldn't be friends anymore". I look at him and say " no I want this friendship, klaus is jellous so let's give him a reason to be".Steffans pov
I look at her and say " are you sure". She nods I kiss her and we fall into the bed and start ripping each others clothes off. After the best sex ever. I kiss, him and say " that was so much better than the sex with klaus, why don't we have an affair". He kisses back and says " it's risky but I want it, if klaus finds out then you can move in, until,then we need to be carful with how we act around eachother ".
