Unruly son comes in begging for an advance on his allowance

In this explicit scene, the ungrateful son bursts into his mom's room, pleading for an advance on his allowance. But, instead of listening to his mother's careful words and warnings about budgeting, his wayward desperation leads him to cross the boundary into more intimate territory. As the mother's patience wears thinner, she surrenders to his bold intentions, and her weak point is where he finally finds his cannibalistic satisfaction - not in the allowance but in a mind-blowing climax, which he forces into her advancing a son-mother-in-law creampie scenario.
