Kota returns home with his mother for a memorial service, unaware that she brought him along to keep his aunts Yuka and Saki entertained. That night, adult nephew role-play puts him between the two women in the same bed. Their loose clothing and unguarded bodies tempt him into making a move. Instead of getting angry when they notice, the aunts smile knowingly and immediately grab his crotch. They tease and ride him relentlessly, using their sweaty adult nephew as a personal sex toy and repeatedly draining him to satisfy their pent-up desire.
