About half a year after starting to live together with her, we were spending happy days. One day, my sister from Fukuoka in Kyushu is coming up to Tokyo. She's staying for a week, so I can't get cozy with her during that time, but oh well, can't be helped. 'Hey! Nice to have you for a week.' Huh? What!? Those aren't small breasts!? 'How about we fuck?' The no-bra giant tits and cute Kyushu dialect dirty talk she has that my girlfriend doesn't, I was overwhelmed and ended up having an affair.
