Marie-san, the big-breasted fluffy older woman who lives next door. She always takes care of me, invites me to her house, and treats me to meals... In the first part, I was invited by Marie-san with J-cup huge breasts to a hot spring trip and finally graduated from virginity! In the inn's room and private family bath, they entangle, torment each other, and irresponsibly inseminate inside her vagina many times... And in the second part, in the sex life after the hot spring trip, her endless interest in the female body and youthful libido explode! In the kitchen, bedroom, and bathroom, the two intertwine their love and desire!
