Imoten

1-3. Onegai Sister
Kid-sister Kana is always hanging onto her beloved onii-chan. But she's not a "kid" anymore, and it's not just "cute" anymore--not for her older brother. How can he tell this adorable girl to quit being so lovey-dovey...? But a tearful kid-sister comes to her reliable onii-chan and asks for help: she felt an itch and rubbed it--and couldn't stop! Is she sick? Oniichan decides he has to check her carefully to make she's all right...

4. BS-I
   Hazumi loves her onii-chan that is more than a mere brother complex. She will "punish" him when he talks to other girls. But her onii-chan doesn't seems to mind.

5. Benkyou Dokoro ja!
   Akito tutors his next door neighbour "imouto" Nao, getting tempted as she's only wearing a tank top and panties!

6. Kururu-chan's Melancholy
   Kururu-chan is in heat, and therefore went to consult her onii-chan at school, in which he (too) happily obliges.

7-8. Oniichan to wa Yobitakunai! (I'm Not Gonna call You Oniichan!)
Chika sees her brother masturbating, calling her name! She decides to tease him...

9. Blunder Sister
   Miku is a sweet imouto, but she's very clumsy. The onii-chan tries to kick her out of his apartment, how how could he, as his imouto is soo cute (not to mention, good at sex).
