Make Protagonist's Sister His Harem Memeber

Ryuki saw that he only needed to do some basic touching, and that was all for now.

Well, she had 100% trust in me, so I needed to show her I was interested in her romantically.

Ryuki thought. He asked for his gift to make Asuka his harem member, and the answer he got was to get physically connected as much as Ryuki could.

Ryuki came outside the house, pressed the bell, and after some seconds, Asuka opened the door and walked out.

She made her black hair in a ponytail, a black top, and white pants. Behind her, she carried a tennis bag.

Asuka came near Ryuki when Ryuki spread his arms and hugged her tightly, "Hello, Asuka. Good Afternoon."

"Well... Good afternoon," Asuka was confused as she returned the hug, and after two seconds of a hug, she looked at him, "What's with sudden hug?"

"I decided that I should hug everyone I meet, it is a positive practice."

"Okay," Asuka nodded, "Then let's go."
