Fuckenstein(2012)

Joanna Angel and Dr. Frankenstein were having their nightly romp, when suddenly he did something that had never been done before! He stuck his fingers in her ass while fucking her pussy. She went wild! This inspired the scientist to create a monster whose sole purpose on this earth was to double penetrate his wife. Of course, things got a little out of hand when his ego took hold of him and his monster creation (with a monster dick to match) got out of control.
