This manga is like my personal addictive drug. Need moar. Need lots.
Everything in chapter 9,5 was SO perfect! I loved the beautifully drawn scenes of breast-sucking (both baby Chiaki with medieval Italian lady and teenage Chiaki playing baby), Harumi's constant tsukkomi (at one point she even gets breathless from yelling too much tsukkomi), Chiaki's adorable reactions -- like how how she falls to her knees in p127 panel 1...
I swear, if Chiaki was a real-life girl, she would be able to get anything from anyone with her totally natural, accidental, unwitting wiles.
And if Harumi was a real-life girl, their story would need a "rape" tag -- because Chiaki is TOO MUCH and can drive any woman to a lust frenzy. Nobody can resist that much adorableness! :P
