The guy roughly fucks in the mouth of a Russian girlfriend in the shower

Joking with my stepsister is one of my favorite pastimes. Today she splashes in the shower with soapy hair. In order to play a joke on a girl, I imitate her friends voice and still make her bend down and take a cock in her mouth to cum in her mouth. The girl discovers the substitution at the very last moment and it seems that she is not very happy about it.
