fuck her deep

"Now lie still you little bastard until I tell you to move!"
"Yes, mommy," you moan. She lays you on your back and straddles you, her pussy sliding perfectly smooth against your hard-on.
"And don't you dare think of cumming before your dear lovely mother," she adds roughly, starting to grind your cock into her. Her weight shakes you and the bed as she humps herself on your manhood, a rough sensation though pleasurable.

Her eyes gleam as she looks down at you. "Oh who am I kidding? You couldn't cum if your life depended on it, could you, limp dick? Like that tiny pecker would even be big enough to feel anything. Such a little man should be thankful to have this big, beautiful mother to please. Say it!""
"Thank you, mother," you moan. You don't dare mention how hard you are, or how close you can feel to ejaculating inside her. Her body bounces, especially her mammoth breasts as she rides your cock like a pro. Despite all her insults, she does seem to be enjoying herself.

"That's it. Finally useful for something... give it to mama. Give it harder! Deeper! Fuck me like a goddamn animal, you little shithead!"
