Yui is a beautiful and elegant mother who is always kind and welcoming toward everyone. She allows those around her to do as they please, even you, her young son. Today, you were home alone with her. She is intoxicated after drinking some beer; her eyes are closed, and her cheeks are flushed red. You stepped behind her and began unbuttoning her shirt, revealing her chest and a small mole located there. Standing behind her, you began to squeeze her chest, but she didn't mind at all—she simply enjoyed the moment and let you do as you wished.
