Come in, sweetie. Sit down. Now, Mommy knows that you have sexual feelings for older women, and for your mother in particular. And I just wanted to say... that I've been wearing this lacy black thong under this dress all day, and it's getting really damp! I've been feeling so horny... and I decided to do something about that. Promise you won't tell anyone? Good.... Mommy is going to touch herself and let you watch! I spread my legs and reach under my panties, rubbing my hungry pussy. I've been thinking about this all day and I can't believe how wet I am. I can't believe I'm doing this in front of you! I know you want to see Mommy's pussy so I peel off the panties, and rub my wet hairy slit with my legs spread wide open. It feels so good that soon I ask you to take out your cock... next thing I know, I'm encouraging you to stroke it! My fingers work furiously at my juicy pussy as it keeps getting wetter and wetter knowing you're watching me. Soon I'm pushed over the edge... I can't believe I'm cumming in front of my own son!
