When I meet my niece again for the first time in five years, she acts as innocently as a child, but she is a fine adult woman. After taking a bath, she hugs me without warning while wearing only a bath towel!

My niece has transformed into an adult woman without even looking at her. She doesn't notice this change in herself and is just as excited with just a bath towel as she was when she was young! But her body is completely adult, so the glimpses of her breasts and crotch are too stimulating! Yes, that innocence is actually a sin. And I erect in agony at the sexy body of such a niece! And my niece behaves in a surprising way...
