the inverted Shotacon series cousin boin's sister, momosaki manami.

The main character's parents and children came to Tokyo from the countryside with their family. Originally a cousin living in Tokyo, Boin's 'Manami' sister gave us tourist information to the main character family. Moreover, because your sister lived in a place away from Tokyo, she is the same hotel as the main character and the same room! A big breasted sister who has long been in love is so close to here!? I try to bathe together and sweeten it in the boin. Two books with "Boin Family Teacher Manami-sensei"!
