You were trained in the art of oral stimulation...

Once your bodies had been augmented for Master and you had been retrained to Mistress Jade's satisfaction, Yoshino and you had been allowed to train at the harem's "finishing school". Other girls participated in different classes. Most of them were other lower harem concubines. Their age and experience hinted that they were likely only a few years ahead of you in training. Most of these girls were taking the "classes" as a refresher. Some were friendly, but you could tell that they had been instructed to keep you at a social distance. As the lowest members of the harem, Yoshino and you still shared a room and you were allowed minimal clothing (a g-string, nipple jewelry, wrist restraints, 6 inch heels, and neck collar). Mistress Jade still carefully monitored the two of you, but a few nights a week you were allowed to associate with a few of the lower harem girls.

Professor Sarah quickly became one of your favorite "professors" within your Master's training academy. She was your instructor for Oral 101 and Oral 201. Not only was she beautiful, but she had risen quickly up the ranks of the lower harem. She was only a few years older than you and was already a "professor" in Master's Harem.

When you started attending her classes she was sporting a massive belly courtesy of Master's seed. Over several weeks you watched it grow further as you progressed in your training. Two moments stand out in your mind...
