I am my own portable self contained cum warmer. No batteries or cord required!

I used one of these at the portable sperm clinic I ran for my unvaxxed loads out of a closed down Walmart.

I am convinced people do this cum thing on purpose, I have never seen it used when there is no possible way to interpret it as meaning ejaculate, it's always cum restaurant or cum tourist or something
