My Cousin Who I Played With As A Child Came To Visit Me In The Countryside For The First Time In Five Years, And Her Boobs Had Grown So Much That I Had To Cum Inside Her For A Week During The Summer Vacation, All Sweaty. Suzu No Ie Rin

Due to her parents' work, my cousin Rin, who moved to Tokyo five years ago, came to stay at my relative Yuzuru's house for a week in the summer. Yuzuru is like an older brother, two years older than Rin. They used to play together often as kids, catching insects and such. With Yuzuru's parents also away at part-time jobs, he reunited with Rin after a long time, but Rin, whom he still thought of as a child, had become cute in the face and her breasts had grown unbelievably. Yuzuru, who usually masturbated all the time, caught a glimpse of Rin naked in the bath and couldn't suppress his erection.
