Melody Mynx is at Derek's office to take part in a paid research project on sensory perception.  Derek explains to her that there will be several tests including a touch test, a mobility test, and a taste test. After touching her in ordinary places like her face, arm and knees, she reports that she is very comfortable with everything and open to moving to the next phase of the "research". Derek then touches her thigh and pussy and she reports that she is getting very wet. After touching her nice big tits, it is decided she can feel things better naked. She then tastes her wet pussy on Derek's fingers, before getting a taste of his cock in her mouth.   We get a great view of her hanging tits and hairy pussy as she shows her cocksucking skills.   Derek and Melody both decide that even though the test is officially over there is no point in stopping now. She really uses her hot mouth on his cock before lots of fucking including some hot standing doggystyle with her tits hanging.  They finally do some hot missionary fucking alternating between pussy and ass and her mouth before he unloads in her hot MILF cunt with a spurting creampie. They conclude the "research" with Melody tasting his cum mixed with her pussy juices. Seems like it was a very successful experiment! (running time 45:12)
