Treebucket
Tree Bucket (n): a sexual act in which the man, wearing an adult diaper, assumes a power stance over his partner, and begins to defecate and urinate until the diaper reaches full saturation. Once the mixture of urine and biosolids spills out of the diaper onto his partner, the climactic moment has been achieved.
After a lovely date at Taco Bell with my girlfriend, we were feeling spicy and primed for Treebucketing!
