Bernadetta x Byleth (tier 2 request) (Patreon)

The professor noticed that a student never attended class and went to her room to give her private lessons. But what he didn't know was that Bernie was a compulsive masturbator, and he caught her red-handed. So she locks herself in her room with the professor, having uncontrolled sex. In the end, the professor rewards her every night if she attends class.
