"....Mary's secret is that she has a dick."
Erika then realized that it was getting late and she was getting hungry. Believing that Mary would also be hungry she closed the book and went to the kitchen, where she made dinner.
When everything was ready Erika went to Mary's room to ask her to eat, but when she opened the door she found her housemate stroking a 7 inch hard cock that she had just above her pussy while smelling panties.
Mary quickly put a pillow on her lap and said "What do you think Erika is doing? Why did you come into my room without knocking on the door?"
"I've never knocked on the door before, since you lock the door when you want some privacy. But changing the subject, is that between your legs the real thing?" Erika said, pretending that she didn't know the secret before entering the room.
Mary looked away saying "What are you talking about? Of course, I have nothing between my legs."
"There's no use lying, I saw you stroking a dick that was attached to you. And now that I realize, aren't these panties you were smelling not mine?" Erika said
"OK, I admit, I have a dick and I was masturbating while smelling your panties." Mary said, since there was no way to hide her secret, that was never a secret for Erika, anymore.
"Can I watch while you finish this?" Erika asked
"Watch while I finish what?" Mary asked
"As you finish masturbating, of course. I want to see you cumming." Erika said
"Aren't you mad that I'm wearing panties that I stole from you to masturbate? Don't you think I'm weird?" Mary asked
"I must admit that it bothers me that you took my things without asking, but you know that I want to become a writer and I like to see different things, as they give me new ideas. You are different and I find that interesting." Erika said
