My Step-MOM Will Only Roleplay With Me if I can Make Her CUM

Description: I've been really into vampires for some reason lately. like, obsessed! i've always been begging my step-mom to roleplay with me. i want to be a vampire slayer and "stake" her. i even saved up enough money to buy her a vampire outfit so that i would do it. after getting tired of my constant begging she eventually gives in. she had one big condition though, i have to make her cum multiple times, or she won't play my little game. so, in the end she puts on the outfit i bought her and grinds my dick until she cums multiple times. she then gets controlling and demands i fuck her missionary style until she cums twice more. then, and only then, does she let me finally cum and “stake” her like i've been fantasizing about.
