I'm just trying to get some homework done in the office and in he comes. I'm not sure what he wants at first, so I tell him step-mom just went grocery shopping and won't be back for a few hours...

but that's not what he wanted at all.
He starts asking me about my experience with boys and suggests that he might like to see my body. I'm a little creeped out but also pretty turned on so I show him my tits, and then my ass, and finally my pussy. By then, I'm so excited that I can't wait to cum for him and call him step-daddy.
