I want to be enveloped by Mom's big breasts... Sakura Mom has nurturing, large breasts and raises Yuu-kun, a clingy, childish boy, tenderly dealing with his bedwetting. In the bathroom, she carefully washes his lower body and gently soothes his innocent little cock using her mouth and breasts. The warmth and softness comfort Yuu-kun completely. To help him understand relationships between men and women, the big-tits mom slowly imparts her maternal role alongside her allure as a woman, carefully teaching him about her fullness and tenderness. Each time they spend together, Yuu-kun feels deeply healed and discovers something new.
