[BKD-356] Mother-son copulation – Marunuma Kogen Road – Iwasawa Kayo

Kayo lost her husband at an early age and lives with her son.

The mother was always kind and loving, so they built a very strong bond.

After the son gets a job and is leaving home, to make a final memory, the two go on a trip to a hot spring together, where things quickly get incestuous.
