I Fucked My Annoying Little Step Sister

I swear I hate my little step sister she's so annoying. Every time I'm trying to just lay in bed she comes into my room and annoys me. I try to tell my mom and dad but they always just say "Let Her watch TV With You." So this one afternoon she comes into my room annoying as usual and I just want her to leave but she lays on my bed which she never does. I She just started to be her annoying self but she also started to rub my leg, and I kinda got turned on but I didn't want her to see that. But of course she did and now things took a turn for the worst and she started to grab and pull my dick out so now I'm worried because first we shouldn't be doing this and second our parents are home. But here goes Heidi telling me our parents went out and we were home alone so what should I do? SMH I told her she couldn't tell anyone and she assured me she wouldn't. So I Fucked My Annoying Little Step Sister.
