Sister has to pay her brother with her ass after losing a bet

Our simple sibling rivalry has always pushed our boundaries, but no match had set the stage for this kind of rife anger, as he slams home his erection, her now defensive and straining cries rendering no aid to soothe. My cheeks flush, crestfallen as his enjoyment of the abduction progresses, bound to the ignominious obligation which sexually compels sisters' desperate compulsion. His sweat drips in a harmony of character-revealing insistence as I personally forgo the rebirth of sisterly intimacy, failing to locate opposition against her partnerís dissolvent hunger.
