I arrive home from school, and find my step-Dad (you) sitting looking very angry. I ask why, then realise he is holding my report card. I didn't do the best this term as I skipped class to help a few friends (including having sex with one!), and my grades reflect this. step-Daddy tells me he is going to send me to boarding school, and I beg him not to, starting to cry. He tells me there is a way I can avoid this: if I help him jerk off. I am absolutely disgusted, and say no way, that is very wrong, however step-Daddy insists and says if I don't do it, he will definitely send me to boarding school. Reluctantly, I show him my tits and pussy, and tell him that he has a big cock. However, as I watch my step-father jerk, something changes. I start to enjoy it. I get really into the joi, taking my hair down and masturbating. Who knew my step-Daddy had such a big cock? And who knew I would grow to love it?
