Seducing the babysitter

Mrs Windsor rang while I was babysitting for them. She's lost her notes and thinks they might be in her bedroom. I didn?t find them but I did find her vibrator and I've just used it to achieve my first ever orgasm. Now they're home and Mrs Windsor has just jokingly suggested a threesome, her hand sliding up my leg as I wonder whether to tell them I'm still just an innocent virgin.  For adults only. Contains oral sex, lesbian sex, straight sex, sex toys, a MFF threesome and masturbation.
