Coo-Ane! ~Cool na no ni Betabeta ni Aishite Kureru Onee-chan ni Mechakucha Amaete Kozukuri Zanmai♪~

Stepsister was known as the "Ice Cool Beauty" at school, charismatic but chilly. She melts with hot flushed love around you, though! "I'm only nice to the boys I like. If you want my soft breasts you just have to say... the... words... mmmmhm." "Your little man smells like sex... I want him in my p*ssy... I'm a bad girl." Onesan! Oppai! Big pregnant milky tits! Consequence-free sex (she's already knocked up)! Sayuki Aihara, older sister-in-law, embraces you with a gentle love deeper than family. But brother-sister love is forbidden by society. You can't be together. One day she sees you masturbating to her though, and you consummate a mutual love. You cum inside her... and the babymaking life begins!
