The wife is sucking the friend’s cock while he holds her boobs. The friend is moaning as the wife uses her mouth and hand to make him cum. The friend cums in the wife’s mouth. She takes her time with him afterwards: she continues to stroke him and use her mouth on him. A nice touch at the end.
After reading some background: this was the wife’s first time letting someone else cum in her mouth. Also, the friend didn’t last long and finished pretty quickly.
