Foot worship / homework exchange with your stepsister

Jack and his stepsister have a good relationship all together, but sometimes Jack is pretty pervy and he's so horny for his stepsister's feet. Just today it was like that. Emily was studying for her German lessons in college and Jack was all the time looking at her feet and almost droolling because of them. She's was so annoyed by that but until the time she needed some help with her homework. That's when she asked Jack to help her with it but you know, nothing is for free...Jack want's her feet and if she'll get to worship them and smell them then he'll help her. She agrees and Jack is so horny about her feet that he does the homework in just few minutes. But she won't let him worship her feet long enough and another foot worship is conditioned on doing all the extra homeworks as well. Jack is hooked, he just has to have to sexy feet again! And no homework will stand in his way!
