Inbo Rannyuu Soukan ~Boku no Seishi de, Mama o Ippai ni Shiteageru~

Once she drifted back down and emerged from her languid post-orgasmic haze, she went to send a type a reply.

He had already left the chatroom.
But then a voice came from directly behind her, in the bedroom.

"I'm here."

It was the voice of her son, Shinya.
