GFD-001 — I want my much younger sister who doesn't even know the meaning of 'service' to innocently let me play with her nipples like playing house — Amane Yayoi

About this work

Can you make my nipples feel it too? After accidentally witnessing her brother's masturbation, Yayoi ends up helping with his nipple play. At first she was bewildered by the act itself, but seeing her brother writhe and his expression made her feel happy, and from a desire to “be more useful” she rapidly improved her nipple teasing in a very short time. ...A forbidden nipple game that awakens a woman's wicked, maternal sexuality.
