now, mommy is VERY angry

INTENSE/EXPLICIT MOMMY HUMILIATION: mommy comes over after a month of you not being able to get your sister pregnant. she's upset she has to take things into her own hands and humiliates you both through the whole thing. she's not sure what's worse: your tiny weiner that your sister can't get hard OR the fact that your sisters pussy is so stretched any worn from taking all those other (implied) BBCs. after getting you hard herself, mommy uses a dildo on you both before getting you to cum in your sisters pussy over and over. after she leaves, you and your sister make love and console each other with love and more light humiliation.
