Super busty young moms "Iori" and "Mizuki" come to celebrate the birthday of cool businessman Yuuki! I'm Yuuki's senior and not very popular, so I pop in to join the birthday party! The young moms are put off by my boring jokes, so I get them drunk and play some dirty games with them, and they're actually into it! They get drunk and spread their legs, exposing their anuses! A 4P orgy breaks out, and I cum deep into their uteruses! What a lucky day today is!
