(1)While receiving a blumpkin and getting ready to climax, you turn around and release it into the toilet. It is then mixed up and ready for consumption by either party.
(2)Climaxing in ones mouth, then it is spit into the toilet bowl with the fecal matter.
(1) Sherry is a freak! After giving me a blumpkin, she mixed up my jizz and shit and treated herself to a blumpkin shake! it was hot!
(2) Once Marge was done blowing me on the toilet, she made me get up so she could spit it out on my poop. She loves mixing up blumpkin shakes.
