Back before COVID-19 I paid a very obese man $400 to come to my house and take a bath. I had instructed him not to bathe for 72 hours prior, and I also had him fart in the bathtub.
When he was finished I paid him and he left. Then, his dirty bathwater was all mine to drink. I guzzled it up like lifeblood. The rank odor of the gray water filled my nostrils, but the only challenge was controlling my erection as I slurped it up. I wanted to save some in a bottle in a warm humid place, but I drank it all.
Not sure if I can do this again because of COVID. Sigh.
