MADN-019 Forbidden hot spring trip with grandson Preventing aging by having grandson's raw in-and-out Wild River Todoko

Recently, Toke started living with her daughter and son-in-law. However, Toke had one concern: while she was highly sex-driven, there seemed to be no signs of nighttime activities between her daughter and son-in-law. One day, the family of four decided to go on a hot spring trip. Since it was a rare hot spring trip, Toke began encouraging her daughter and son-in-law to have sex. However, as she talked about it, Toke herself became excited. The couple was soaking in the hot spring. In the room were only Toke and her grandson Tatsuya. Toke reached out her tentacles towards Tatsuya.
