Oh my GOD! You are such a pervert little brother!!!! I can't believe you just waited underneath my pile of clothes till I got in here, what're you doing, trying to see me change!? I told you to stop doing that! You have to get out of my room right now! But... you can't now because you have a BONER!? oh my god. You ask me to stroke it but i'm not gonna do that. We do have to get rid of your boner though sooooo how about, how about I just tell you what to do with your dick? I'll just give you instructions. Since I'm just your sister and not like, a well trained person on this, it takes me a while to get into it but I do a pretty good job at telling you what to do...specifically demanding that you stroke your cock a certain way, making sure it feels good for my little brother! in conjunction of course, with a little lighthearted sisterly teasing. In fact - I even start to get sort of... into it! I demand that you suck on my nipples and it starts to feel too good before I ask you to hold off.And now I'm getting horny and wanna make you cum before I kick you out of my room and get back to uh... what I was doing. ;) I think we might have to do this again sometime little brother...************************** tags: sister, brother, stepbrother, stepsister, joi, jerkoff instructions, jerk off instructions, stepfamily, jeans, titties, breasts, hiding, sneaky, younger brother, younger man older woman, older sister, big nipples, mama fiona, goddess fiona, fiona costello, high waisted jeans, cum instructions, cum countdown, long nails, eyeliner, makeup, big lips, taboo, taboo fantasy
