"I like pine needle breakers. That shape pierces the deepest and stimulates Portio." Rieko Masaki, 48 years old, is a full-time housewife. A family of five with a husband who is in his 26th year of marriage and three children. The couple are still in good shape, and they have night activities once or twice a week, but Rieko seems not to be satisfied at all. "He may not mean that, but sex with his husband is a regular ritual to confirm the relationship between the couple ... There is no such thing as a hot thing that makes each other feel really good today! Maybe it's just that you're old ... "The quality of sex has clearly changed from when I first met. "I still remember how comfortable it was when I first got my vagina." I want to drown in pleasure like that day when I first learned the true joy. With that in mind, Rieko's first affair experience is the start.
