i lost my virginity in a languid summer countryside... During summer vacation, i, a student, returned to my father's parents' house for the first time in a while. that night, after taking a bath, i peeked at the sex between my uncle and his wife, yuria-san. yuria-san, shaking her sweaty big breasts and shaking her hips violently, is unimaginable from her usual gentle appearance. that figure sticks in my mind even the next day. suddenly coming to my senses and looking up, yuria-san was smiling at me.
