Um caso mascarado de identidade errada

So Ms Paris is resting with a blindfold on when a masked man comes in the room. As he pulls the covers back she starts to take off the blindfold but he touches it and she thinks it's her guy and this is some kind of sexy role play. After a blowjob, doggystyle and some pounding missionary he cums on her stomach. As he is leaving she takes off the mask and is freaked out that it's not her guy. He reveals his face to her and she immediately is angry because she know it's her STEPSON!
