You were throat fucked on your back...

Professor Sarah was helped by more senior "student" over to the table. She cradled her full belly with one hand and rested her other arm against the table. It was crazy that she was still wearing those ridiculous high heels!

"Areli, why don't you go first?" She said causing your heart to sink into your chest.

You had hoped to learn from watching another girl. Bravely you had stood up and approached her at the table. You'd felt your large naked breasts bounced with each of your steps. The rubies dangling in strands from your nipple rings had tickled your sensitive skin. The click of your high heels had filled the silence as all of the other girl's watched you approach the table and lay down.

Professor Sarah positioned you on your back with your head hanging off the front of the table. Your wrist restraints were bound to either side of the table. The table had been short, even for your 5'2" form. Your legs hung over the back and your ankles were bound to each table leg causing you to painfully arch around the table.

Professor Sarah had another student check your restraints. In her very pregnant condition, walking around the table had been too much. She leaned heavily on the table and when you looked up at her you could see down her low-cut dress at her full breasts. Pregnancy suits her, you had thought.

You prepared yourself for what was to come. You had known you would be throat fucked in this position as it was Master's favorite. At the collaring ceremony you had seen why. Master's massive cock was a foot long and very thick. This was the only way a woman could take all of him down her throat!

Two things had given you hope:

1. First, training sessions were never permitted to use mock cocks that were equal to the size of Master. It had been explained that Master wanted to save something for his concubines to experience uniquely during his sessions with them. Additionally, Master wanted his females to remain tight for his enjoyment.
2. The other thing that gave you hope was that your throat's gag reflex had been removed. The process had been frighteningly unpleasant but it was an "investment" that you hope paid off now.
