The sexy dental hygienist sister is the best, isn't it!! Hina-san, who I got close to at my regular drinking place, is just like that and is incredibly sexy. She's also interesting to talk to and her Hiroshima dialect is charming as hell!! But there's one big drawback... she's living with a man... and her boyfriend is a strict, big guy!! It's the worst, but you can't change your back for your stomach, so today I'm going to try my best to seduce this sexy beauty again, haha!!
