When they meet again after a long time, the aunt still treats her nephew like a child, and when he is taking a bath, she comes into the bathroom to wash his back like she used to. However, the nephew can't resist the sight of her aunt's big breasts and gets an erection. When the aunt notices this, she becomes curious about the nephew's uncircumcised penis and starts touching it aggressively, and the nephew can't contain his excitement either, so he follows her lead and touches her body all over, and the two of them end up having sex.
