Wet Russian chick gags on her buddys cock

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.
