In her.

"In... in me," Yuika panted as her pussy spasmed around the dildo.

"Interesting," Shoko noted. She pulled out of the schoolgirl's drenched snatch and removed the strap-on from her waist.

"I never had someone cum inside me before," Yuika said, taking her legs off of the chair's armrests and closed her thighs out of modesty. "It felt... different. Very hot and oozy when it leaked from my pussy."

"Are you on birth control?" the doctor asked her.

Yuika shook her head and glanced at her older sister. "I... we... I mean, the boys who I have sex with wore condoms."

"I will prescribe you Levonorgestrel as an emergency contraception," Shoko suggested. "Take it as soon as possible to avoid the possibility of getting pregnant."

"Pregnant?" Yuika gasped, finally realizing the consequences of her action the night before.

"I will also write a prescription for birth control if you decide to continue to have unprotected sex."

"Yes, doctor," Yuika nodded.

"Thank you, Dr. Sugimoto, for helping my sister," Mari nodded her head slightly.

"Is there anything else I can help you with?" the doctor asked.

Mari looked down at her hands on her lap.
