One day, Towa witnessed her brother trying to masturbate. She desperately tried to stop him, but her brother begged her, saying he didn't want to die like this and asked if she could let him practice sex. Reluctantly, Towa agreed under the condition that they wouldn't kiss. From the brother's request for pseudo-intercourse, Towa... It didn't end with just pseudo-intercourse; the forbidden sibling copulation escalated into a level of pleasure involving raw penetration, urination, and splashing!
