Ikuta Atsushi is a private tutor who was assigned by his senpai to take on some of her clients as additional workload relief. He arrived at the first girl's house and was surprised by the nice surroundings, but even more so by the bombshell that greeted him when he opened the door. The girl's mother introduced herself and apologized for her daughter's behavior earlier. It turned out that the girl was cute too. To his surprise, the other client who needed tutoring was also attractive and had a beautiful mother as well. Additionally, all three of them were sexually frustrated. Ikuta Atsushi was excited to use his knowledge to help them satisfy their desires.
