Visiting My Step-aunt Part 1

I am with my step-aunt for the week, and I can't help but notice that my step-aunt is SEXY!  She went out for the evening, so I sneak into her closet to sniff her underwear, not realizing that she would be home so soon.  I am in her closet, her panties wrapped around my cock, jerking it while thinking about her wearing them, when my step-aunt comes into her room.  I freeze, panicked, as she starts taking off her dress, her heels, and then her bra and thong.  Once my step-aunt is totally nude, she lays back on her bed and starts rubbing her pussy, and I can't help but peep from her closet. She fingers her MILF pussy, spreading her pussy lips as she gets closer to cumming, getting ME closer and closer to cumming.  Then, amazingly, my step-aunt squirts - A TON - as she cums, and it drives me wild.  She takes out her vibrator to get herself off again, then squirts some more.  She is so sexy moaning and squirting all over her bed, and I feel so lucky to be spending the week with her.
