The second Keiko reached for her assignment, Vanessa stepped forward in one swooping motion and pushed the girl forward, setting her off balance so she fell over the desk. It had been cleared appropriately before, and all that fell astray was a single pencil. Vanessa quickly pressed up behind her, pushing her hips against Keiko’s and pinning her in place. The rope was already uncoiled and looped under her arms, and when she pulled, it tightened, drawing her arms tightly behind her at the elbows.<br/><br/>Expertly, she circled a few more strands around her elbows, and within moments a strong, impenetrable knot sealed the bindings. Vanessa pulled her up by the tie back to her feet, and still before Keiko knew what was really happening, she reached up her skirt and grabbed her panties, jerking the thin undergarments down her legs. They stretched as they caught on her shoes, but then came free, and in the next instant she was wadding them in her hand.<br/><br/>“I think these will do nicely.” She released her iron hold on her student’s arm to reach up and pinch her nose shut, then pressed the wad of cloth to her lips. “Open.”<br/><br/>Whether Keiko actually complied, or just opened her mouth in a breath of panic, Vanessa stuffed her own panties deep into her mouth. The garment was surprisingly filling. Before she could worm it out of her mouth, she picked up a roll of clear packing tape that had been sitting on her desk, a tab conveniently started and pressed it against the panties, then spun it around her head half a dozen times, sealing them in tightly.
