Creampied by my Step-Brother's Bully

You've been bullying my little step-brother at school and I invited you over so I could try to convince you to leave him alone. I'm really sweet and kind of shy but I try to talk some sense into you. You listen for a couple of minutes but tell me that you'll only leave him alone if I strip for you. I can't believe you would even say something like that!! At first I refuse, but eventually I decide that if it means you'll leave my step-brother alone then I guess it's worth it. He's a nice guy and he deserves it, I make you promise that if I strip then you'll stop bullying him. You swear you will. I strip down to my bra and panties but you tell me I need to be FULLY naked. I'm pouty, sad, and I can't believe you're such an asshole!! I get fully naked even though I'm super pissed that you're making me do this. It's worth it though, for my little step-brother. You tell me it's not good enough and that you want to fuck me. I berate you for being so awful and lying to me, but eventually I agree. I tell you we can only fuck in missionary because I am NOT going to enjoy this and I don't want you to see all of me! I lay down on the bed in front of you and you take out your cock. I'm a little surprised at the size of it but still not happy about this. You slowly start to fuck me and I start to seem less and less mad with every thrust. My moans make it obvious that I'm enjoying having you inside of me but I still try to hide it. I can't take it anymore and I admit that your cock feels so fucking good inside of me. I start to loosen up and stop trying to hide the fact that I'm loving this. I turn around and ask you to fuck me from behind. I've never had a cock feel this good before! I tell you to fuck me harder and beg for you to cum inside of me. It feels so good when your cum starts pouring into me. I finger the cum out of my pussy for you and let it spill on the bed and on your cock. I'm totally in love with your cock AND your cum. I lick all the cum off of your cock and scoop up the cum that got onto the bed. I lick my hands clean because I love the taste. I swirl it around with my tongue and let it fall out of my mouth for you, I'm just obsessed with your big load!! I tell you that I don't care anymore if you keep bullying my step-brother, I just need you to keep fucking me... all the time. Please?! I need you.
