New toys

Professor Johnson opened the drawer of his desk and pulled out an inflatable anal plug along with a bottle of lube. He smiled to himself, as it was time to prepare Hannah for the next step in her training. Slowly, smearing the plug with lube, he turned Hannah around and bent her over his desk. "Spread your cheeks for me, slut." he asked, as the young girl put her hands around her buttocks and pulled outwards, revealing her tight asshole.

Slowly, Professor Johnson prodded her virgin hole with the tip of the plug. Hannah could feel the coldness of the lube against her ass as it slowly stretched open her butthole for the first time. Surprisingly, it Hannah didn't feel any pain, at least not yet. Of course, this was due to the design of the plug: it was about 7 inches long but only about a centimeter wide, but would expand to a much larger size and stretch the ass of the wearer once pumped up. Soon, all 7 inches were in Hannah's tight little asshole, with only the base of the plug and the pump poking out. Hannah felt like it was stuffed halfway through her intestine, the fullest feeling she had ever felt in her young virgin ass.

"Relax, Hannah." Professor Johnson said, and started pumping the inflatable plug. As the pump inflated, the fullness in Hannah's ass transitioned into pain as her ass was slowly stretched by the expanding plug. Hannah writhed on the desk whimpering, tears streaming down her face, as the sensation of her ass being torn open shot through her body. However, the harder she writhed and tensed her muscles, the worse the pain got. Finally, after 30 seconds of pure agony at getting her ass stretched for the first time, her rim finally gave way and the inflated plug popped out.

Professor Johnson slowly inspected her now opened hole which was now only slightly gaping, but only barely so, before shoving the plug back in her butt. After repeating the process a few times, and when he felt her ass was sufficiently stretched for the day, Professor Johnson finally let Hannah go home.
