While sitting on the toilet Winnie thought about Cheryl's efforts to teach Winnie the art of auto-cunnilingus."If I let you out of the chastity pierci...ng you should be able to entertain me...We've had you rub your sad old clit on furniture with your hands cuffed...used cucumbers...let's see if you can jack your legs over your head and eat yourself out."
