What if there are people out there who cums at their wall crack

No, I'm not entirely trolling, it's an actual thought that struck me when the cashier lady was scanning my groceries.

I'm like ok what if a person thinks:
"I have nothing to blast my cum at nor can I find a human genital hole to jizz. Oh look, I see a crack at my wall that I haven't fixed yet, I'm gonna spurt at it with or without intentions."









(Um sidenote: I think the cashier lady was staring at me because I was laughing. Uh I hope she forgets about my existence °////°)
