Chapter 1

"Give me some from yours" Sana

Tzuyu almost had a heart attack because of the latter "Are you out of your mind!?"

Sana immediately cover Tzuyu's mouth with her hand "Keep it low! Mom and Dad might hear you"

Tzuyu remove Sana's hand, away from her mouth. Sana then handed the latter a test tube.

"Just put it there, I need it tomorrow" Sana said, and leave Tzuyu's room.

"She's insane" Tzuyu hissed, she then get up from the swivel chair and walk to the door to lock it.

Sana's a nursing student, while Tzuyu's taking up architecture. It's really weird to say but the two are really close despite of always bickering, they still treat each other as siblings.
That may be the reason why they always have a sibling's fight.

Tzuyu pull down her shorts and sat on her bed. She then started to masturbate, but half an hour had passed and her friend's not getting hard.

"Come on men! My evil sister needs to pass her subject" Tzuyu hissed

Another half an hour had passed, but nothing happened. That's when Tzuyu decided to go into Sana's room, which is beside her's.

Tzuyu stood and pull up her shorts, then went to Sana's room without knocking. She found the latter in front of her study table and reading biology book.

"I can't do it" Tzuyu said as she walked in and close the door behind her

Sana flinch out of surprise, and turn her chair to face the latter "What do you mean you can't do it?"

"No matter how hard I try, it's not getting hard" Tzuyu

"You're not getting hard?" Sana asked in disbelief.

Tzuyu nodded, she then look down feeling so shy.

"Just think of dirty thoughts" Sana

"But I can't even think of one" Tzuyu replied

"But I need that tomorrow" Sana

Tzuyu lift her head and protest "What can I do? I can't do it"

"Just try again" Sana

"I already did... Why don't you do it?" Tzuyu

"What!?" Sana exclaimed

"Why don't you do me?" Tzuyu suggested

"Are you out of your mind?!" Sana yelled in anger

"You're the one who needs it" Tzuyu

"But I won't do that!" Sana

"Then asked for someone else" Tzuyu replied "You can't get any from me, I can't really do it" She was about to turn around but Sana held her arm, which made her stop

"Yah! Tzuyu- yah! I'll fail if I can't get some" Sana

"Well it's not my problem" Tzuyu

"Please.... Try to watch porn" Sana suggested

"I don't like those" Tzuyu disagree

"Just try, maybe that can help" Sana pleaded

"Fine, but I don't have any" Tzuyu

"What are you? An innocent child?" Sana then get up from her seat and pull Tzuyu, she then made the latter sat on her bed "Do it here"
