You have came to see your therapist sister about a problem you have. You tell her all about your panty fetish and how you like stealing HER panties! She is shocked and grossed out but tries to stay professional. She is reluctant to help at first as her method is a little hands on, and it wouldn't be right with her brother. She instructs you to get your hard cock out and masturbate, she takes her panties off and makes you sniff them while saying how gross it is, until... she sniffs them herself and then instantly gets turned on, she plays with her pussy sniffing her dirty panties until she cums!
