Justin was pleased with the ease in which he had turned the pig boys into girls. For a moment, he looked across the orgy scene to see Mr. Hawkins watching him. Mr. Hawkins looked mildly impressed, but there was something in his expression that convinced Justin that he was expecting more.
Justin turned back to the sow girls and focused on his own transformation. His lower teeth grew into tusks and dark brown hair grew all over his arms, legs, and chest. His body grew and swelled until he had become a muscular, seven-foot-tall anthro boar.
Justin pounced the sow girl on his left and pressed his meat deep into her sex. As he exercised his power over her, he felt the mental link between himself and the two sow-girls. The second girl simply sat and absently stroked her pussy as she watched him fuck the first girl. Justin opened the mental defenses of both of them and absorbed their power into his own.
When Justin was finished with the first sow-girl, her body was softer, paler, and younger-looking, perhaps only 14 or 15. Justin slid his cock out of her and moved on to the next girl, doing the same thing.
"Time's up!" said Mr. Hawkins. "Prepare to be graded!"
Justin sat up and waited for Mr. Hawkins to reach him. The sow-girls leaned against the boar-boy's body meekly. Justin smiled, fairly confident that he was going to get a good grade.
