oatmeal cream pie surprise
When you hold back your cum for so long it turns into a thick, gloppy mess, then you go at it like a madman up your butt or in your snatch until you finally blow your load.
I waited three hours just so I could slam my cock in her ass and let it all go like a fat kid at a buffet.
He held it in for so long his cum looked like cereal in milk, then he fucked her until he was screaming.
She didn't cum for two days, then she went at him like a beast and sploshed all over the bed.
