When I met my niece for the first time in a while, she suddenly hugged me and became strangely attached to me. So I decided to play doctor secretly (without my family finding out). When I started the examination with water guns and marshmallows, my niece's body was sensitive... and she made a strangely seductive sound. My niece's lower body was soaking wet, and before I knew it, things were escalating... and I gave her a thick injection in her little pussy! I prescribed a large amount of white medicine into my niece, who didn't know anything. Playing doctor is a man's dream after all.
