Because she is a new teacher, Karen always tries to work hard, as a result of which she suffers from sleep deprivation and frequent dizziness. Yuki is the class president, he is a good and cute student, so Karen has a very good impression of him. Today, on the way home from school, Yuki suddenly saw a woman falling on the side of the road. He hurriedly approached and asked, only to find out that it was his teacher Karen! Hurriedly took Karen to her house, and as soon as she got home, the teacher fell asleep as if she had fainted. Worried about Karen, he didn't come home, but sat and waited for her to wake up. Watching her beautiful body while sleeping makes Yuki's cock quickly stand up. When she woke up, she saw that Yuki was worried about her, so Karen felt extremely touched. She cooks food for Yuki and shares with him about her lover. It turns out that Karen's boyfriend is always busy, so the two haven't seen each other for a long time. Karen immediately asked about Yuki's girlfriend, he shared that it was difficult for him to have a girlfriend because... Sexual desire is too high! Having not been fucked for a week made Yuki feel extremely uncomfortable inside, the teacher hadn't seen her boyfriend for a long time, so he knew for sure that she was also extremely hot. And then he took the risk of fucking her. And as a result, he was right. At first, she refuses, but Karen quickly catches up with Yuki. Partly because she was touched by Yuki's kindness, and partly because she hadn't been fucked for a long time, Karen quickly followed him. The two continued to make love to each other throughout the night, each time Yuki was cumming inside Karen's uterus. The two are no longer teachers and students, but like a loving couple, enjoying happy moments together...
