Renee never describes herself as sexual in nature. The naturally unnatural look of her body just attracts a sexual energy and attention to her. Enough so that usual come-ons, even from unusually attractive people, tend to turn her off.
However once in a while, the floodgates open and Renee has an insatiable feeling explode from herself. At work it becomes apparent with a higher pitched voice and a much more prominent hip sway. The willpower of a Goddess, Renee fights the urge to take up the first person on an offer for intimacy. Instead she tries her best to make it through her shift, usually with higher tips due to becoming a more playful flirt, and to just get home.
Once at home, Renee tries to sate her desires and need to be filled. She imagines hands running up over her massive curves. A runway of her body as every part of her is caressed; culmiating in her delicate slit being penetrated. Her mind wanders to multiple partners as she slips into a climax.

Her body shivers, joints lock, her back arches and after a few orgasmic seconds, her body goes limp.
She breathes to regain composure, cleans off her toy, places them in a box, and, like a camel leaving an oasis, she's set for a long while.
