Brunette with mask is fucking her friend

Movie description: Bill is hanging out at the party, drinking water, because he's his wife's designated driver. He's sitting around all bored as his wife lives it up. Luckily, Sovereign Syre is around and she finds Bill kind of cute, so she leads him off to a quiet room in the house and seduces him. After all, it's not fair for Bill's wife to have all the fun at the party.
