Get the Dump-A-Hump mug.
This sex act sits firmly in the feces fetish category. For any woman who enjoy the aroma of a freshly pressed loaf; you my consider trying the dumping hump. She blasts into the bathroom while her man is vacating his bowels. Excited by the powerful odor she immediately becomes wet. Using whatever method is preferred, she gets her man erected and climbs aboard. In the perfect Dumping Hump scenario she will try to press her own log on top of her mans through the very small opening left on the toilet as she is cumming. Extra points if she can bank it off his balls.
Abigail know Chester was in the bathroom taking one of his massive post buffet dumps. It always surprisingly aroused her when she could smell it wafting through the door. She decided tonight was the night she was going to try the dumping hump.
