I just turned 18 and want to go to the prom so bad but my step-dad needs to sign my permission slip. He said he'll only sign it if I can prove to him I am experienced and know all about the birds and bees. So I start off by giving him a titjob ending in my step-dad emptying his load onto my chest. Then I take his cock 2 different ways, one being an up close reverse cowgirl ride, and both ending in creampies.
