From today, I'm the master! I'm lending 300,000 yen to my sister Hikari. If she doesn't repay it, she'll do "anything" I say. I'll make her do whatever I say as promised (laughs). Turning my tsundere older sister, who always looks down on me as a maid otaku and a creepy otaku, into an obedient maid! I can do whatever I want with her F-cup bouncy breasts! Anywhere! Anytime! I'll squeeze them! I'll lick them! And I'll fuck them too! Even while muttering, she serves my dick with a contemptuous face!
