Brea Rose - Your step sister in law's step-daughter

Your wife tells you that her step-sister is having a nightmare with her step-daughter Brea so Brea has come to stay with us hopefully only for a little while. That night, Brea comes and joins you on the sofa wearing only a t-shirt and thong, she starts watching TV with you then lays her head on your shoulder, and starts to stroke your leg. She then goes to unzip your pants but you say its wrong, you're married and shes young but you eventually give in, she jerks and sucks your cock (only seeing top of head) before you cum in her mouth. She is horrifed with you and spits in out into her t shirt, calls you a pervert and storms off. Heavily based on a storyline, playing two roles, subtitles and shot POV handjob and BJ.
