Ooh hello Sir! I've brought you a cup of tea to enjoy while you're working in the professor's study for the afternoon, and I do hope you won't be disturbed if I quietly do a little bit of cleaning in the background? What's that? Oh, that's just my butt plug - the professor likes me to wear it as part of my uniform sometimes! You watch me provocatively cleaning the floor on my knees, with my tiny apron hiding nothing! And I can't help noticing that you seem to be getting rather - excited. Why don't you get your cock out? And I'll play with my pussy. OMG, do you want me to sit on your face? Oh wow that feels amazing! I soon cum from the attentions of your tongue, and naturally, I want to return the favour. Are you going to cum all over my face? I start sucking your wonderful cock, wondering how this adventure will end...
