[Fry Dish (Jakko)] Loved and Dominated by the Abandoned Elves I Saved

A kindhearted young boy takes in two abandoned elves, never suspecting his good deed would come due as their ravenous, doting debt. The curvy pair repay him in shifts—the bubbly one rides him with breeding-mad hunger while her masked companion smothers him in deep kisses and grinds her huge ass down until morning. Between rounds of breast-smothering affection and teasing demands that he say "please" before they'll get any naughtier, the two sisters turn their rescuer into the most beloved boy in the house.
