出会い系で知り合った優衣は結婚2年目の人妻。旦那はあまり家に帰ってこないらしい。そんな彼女の容姿はというと、乱れた黒髪にダサいメガネ、地味な私服でお世辞にもいいオンナとは言えない。しかし、メガネを外し全裸になった彼女には驚いた！まさしく原石美人だった…。Yui、 whom I met through a dating sight、 has been married for two years、 but、 her husband does not come home very often. She has messy black hair、 unfashionable glasses、 and plain clothes、 overall she is not very attractive. But when she took off her glasses and stripped naked、 I was surprised! She was truly a diamond in the rough!
