I have a huge crush on my step-sister. She always makes things fun around the house. She is only a couple years older than me and if our parents weren't married, I would totally try and get her attention and affection. It can sometimes be slightly awkward living with such a hot step-sister yet knowing I cant do anything with her sexually. I have jacked off thinking of the things I would like to do with her more times than I can count. Step-Mom sent step-sis outside to work on the pumpkin centerpiece for our annual household holiday dinner which I saw as a perfect opportunity to watch her while she gets messy in pumpkin guts. I would watch her hands skillfully wrapped around the carving blade as she has her way with what is supposed to be our table centerpiece then sneak back inside to my room and imagine her hands wrapped as skillfully around my dick. I guess I pissed her off by being outside and interrupting her creative time.
