Little stepsister needs lessons

Oh! I am SO excited about my little stepsister's birthday today, aren't you? Look at my pretty outfit that stepmom got me all dressed up in, don't you like it? Hehe... I know you'll like it better later when it's off, right? I've been thinking stepDaddy.. since it's little stepsister's birthday.. maybe it's time that I helped you start teaching her to be a good little stepdaddy's whore like I am? Pretty please Daddy.. I'll be the BEST helper ever. I will teach her everything you taught me and we can give her lessons over and over and over again until she likes it and she's real good just like me.. Please... lets give her a birthday present she'll NEVER forget... Cum on....
