[Yamahata Rian] Marriage based on point system [Spirtohleb]

On their wedding anniversary, a woman in a polka-dot dress gleefully threatens her masked, bound husband with a whip, vowing to punish him extra hard. She insists he stay awake so he can cum tonight, warning that passing out means he won't get to cum, and declares she will continue the torture until he cums three more times without stopping. Finally, she presents a special 'humbler' device as an anniversary gift, affectionately calling him her 'slave husband' while he struggles in bondage.
