My Wife Insists

My beautiful Asian wife is a clean freak. Every now and then she insists my penis needs to be 'maintained' which means cleaned. The hair has been lasered and I shower often, so I feel it's always fairly clean. She doesn't agree. We start in our bathtub. We are fortunate to have a tub big enough that we can both get in comfortably. Anyway, she gets soap and a cloth, and cleans the outside of my penis thoroughly. She clearns my scrotum as well. It doesn't take me but a minute to get hard. She claims that's just a side effect. Then she insists I must be cleaned from the inside out. I must get rid of the 'waste' material. She strokes my now almost bursting cock. It doesn't take long, before I'm ejaculating hard and heavy. She then washes that off her hand and my belly. She lets me know that in a few days, I'll have to undergo the whole treatment all over again - to stay clean, of course.
