Bonus creampie

When you have a wound on your dick that gets infected to the point where a blister/bubble of puss forms on your dick, during sex the bubble will explode inside of them. Of course i'll be more liquidy but, if it explodes early you can use it to

lubricate them!

"Broo, You know that infection I had on my dick?"}
"yeah why..?"
"Just had sex with your mom and it blew up inside of her, could say I gave her bonus creampie"
"fuck you, honestly"
"lol"
