Sis and I have been doing a lot of flirting the past few weeks. I noticed that she started wearing more revealing clothes than usual.. I think she just loves being a little tease. But the weird thing is that she still has a boyfriend! Sis always talks about how much she hates him and he can never fully satisfy her.. I know she's using me for her own kink. I guess messing around with your brother is one way to fill the void that her boyfriend doesn't even know about. My sister and I haven't exactly had sex yet.. But our hands have wandered to places that siblings shouldn't touch. No one is home but us, and it would be super risky to fool around here. But this could be my only chance to finally fuck my sister! I go outside and start to creep on her.. This is so messed up, won't Mom and Dad be home soon? Mom is at work and Dad said he's picking up food, he won't be here for a while You don't know that, he could be back any minute Come on sis, I know your boyfriend isn't able to make you feel like I can But it's so wrong.. -She acts like she's not into it, but I know my sister better than she knows herself. It won't be long before she gives in and goes down on me- I think you should put it in your mouth What?! No you're such a perv You're just as much a pervert as I am, come over here After not a lot of convincing, my little sister finally wraps her pretty lips around my thick cock. I love watching her mouth suck me off, I can see her spit running down my dick. And every time she pulls my cock away, there are little strings of her saliva coming off her wet lips. I don't think your cock will fit inside of me bro You'll never know unless you try it I've never had anyone as big as you, my boyfriends cock isn't even half the size of yours! Don't worry, I'll try not to be too rough with you.. Watch my sister slide her pussy down onto me, I can feel my huge cock stretch her insides out. She starts out slow, trying to get used to me filling her up completely. But the best way to get used to a dick this big is to go all in! I bend her over the chair, and pound her pussy from behind right in our parents backyard! Sis might be petite, but her ass looks great up in the air in doggy. We thought we heard someone on the corner of the house, so we go over to the table where no one could catch us. I can't even imagine what would happen if the neighbors saw us, or even worse, our own father! My sister begs for my cum, and after getting lost in how good her pussy felt, I just shot my load deep into her wet cunt! I swear I didn't mean for that to happen, but sis just feels so damn good! She might be pissed that I came in her, but I'm sure this won't be the last time we fuck
