What are you doing on my bed?! It's none of your business where I was... why are you in my room? Get out! Whatever... don't even pull that blackmail with me. It's not like you don't stay out late and sneak in either. Besides it doesn't matter if mom and dad ground me, I don't have any plans.... oh no! I do have plans! I have that thing next weekend, I just can't get grounded now! You just can't say anything to our parents, you just can't!! Oh why are you being such an asshole? I can't believe you are going to blackmail me. What do you want?? Well, what it is? What do I have to do?..... OMG.... NO way.... that's SO gross! Why did you pull that out? Put it up! I don't want to see your PENIS! That's so sick! There is NO way I am going to put that in my mouth... you can't be serious. Why would you want your sister to give you a blowjob? You are such a perv!... Oh I can't believe I have to do this.... I hate you SO much right now! Eww it's going to make me *gag*! So are you actually getting off to this? Ugh, You like it when your sister sucks on it? Well... it's not as bad as I thought it would be.... I mean, it's not totally gross or anything.... actually, it's not so bad...your cock is big and hard.... I guess I almost kind of like it! You can't tell anybody though, this would be SO bad if anybody found out... especially mom and dad! Now hurry up and finish already! And you better give me some warning before you cum... if you do it in my mouth I am going to be so pissed!!
