As a student taking exams, I was constantly getting masturbated by my super-sexual aunt who has had sex with my husband every night, and I became awakened to sexually...and forgotten everything and ended up falling in a series of creampie sex.

Yuu ends up staying at her aunt Ran's house for a while during the summer course. However, she is still living her life without learning because of her unconscious sex appeal... Ran, who was not satisfied with her husband alone, was in agony, but was attracted to Yu's young, strong cock, which he accidentally witnessed, and vented the sexual desire that had been accumulated in the air. Then, Yuu feels awakened from having sex with her, and as crazy as a monkey, he violates her. Ran, who has learned the pleasure that his husband cannot get from his intense rhythm, is also a little unattainable...
