Miyu, a tough mother with a big voice, attitude, and even huge breasts, is always arguing with her rebellious son! However, her son has recently noticed that his mother, who his friends have been praising as "beautiful" and "sexy," has a sexy body when he looks closely. One day, while Miyu is taking a nap, he becomes fixated on her defenseless, big breasts and becomes aroused! Miyu, who teases her son, can no longer contain herself and forcefully attacks him, and despite her reluctance, she cums! The son comes to his senses and repents, but once Miyu cums, his attitude changes drastically! He turns into a spoiled mother, repeatedly asking with a sidelong glance, "Let me cum again..." and they end up having sex again and again!
