No rest for the wicked...

And just as you were enjoying the serving girl's administrations, you hear a knock at the door!

Stacy jumps with a start, but you motion for her to hide beneath your desk, hidden from sight, and once covered you slide her head gently back over your pulsing erection.

She grins and as you call for the mysterious visitor to enter, you feel her slowly submerge your cock in her mouth. It is a warm succulent motion, and you play with her hair loosely with one hand, whilst arranging papers on your desk with the other.
