Impregnation on LetMeJizz
The fantasy of putting a baby in her does most of the work, and that devotion is why the category holds such a steady following. Dirty talk about filling her up and timing it right runs through nearly every scene, turning a plain creampie into something with stakes. Bare cocks, deep finishes and a man holding her hips down to keep every drop inside are the usual markers. None of it is real, of course, but the framing of consequence is exactly what people come back for.
