Cincinnati waterfall

When your partner is sitting on the toilet and you sit on their lap facing them. Then you urinate into their belly button while shitting through their legs, and the pee drips down into the toilet like a waterfall.

Darryl gave his wife the ol Cincinnati waterfall last night, she kinda liked it I guess.
