SPRD-928 My Son's Cock(Huge) Is Bigger Than My Husband's(Tiny) That's The Deal With My Family Mizuki Sakamoto

The so-called ordinary Sakamoto family. My husband and I are on good terms and our son is growing well. However, I was dissatisfied with sexual intercourse with my husband. Still, I was satisfied in the past, but Mizuki, who was in the prime of her life, was unsatisfactory and couldn't help it. After having sex with her husband for the first time in a long time, Mizuki, who is incompletely burned, noticed that there was a tremendously large thing in her son's crotch when he came home. A very big sausage that is different from my husband's. Mizuki was daydreaming and grinning. One day, Mizuki, who was consulted by her son about her first act, said that she did not want to let go of the gem, so it would be a good start to give her son a hand.
