I knew my stepsis has been looking at my dick every time she got a chance ever since out parents got married three months ago and I ultimately decided I just had to fuck her. I love slender damsels with tight fuckboxes and my stepsis fits my sexual preferences perfectly. I had her sucking my dick in no time, came on her face, then got another blowjob in a shower the next day, fingered her in bed and nailed her with no rubber. I plumbing love my fresh family!
