I caught a large-built female student. At first glance, she appeared to be a dull, insensitive girl, with every part of her body seemingly one size too big, far from sensitive—but when lightly caressed, she immediately writhed her body in sensitivity. Under relentless vibrator stimulation on her clitoris, Akiko writhed in agony, reaching climax while helplessly pissing herself. Standing there awkwardly, she seemed like the type who wouldn't flinch over minor things, yet this vulnerability reminded me she was still, after all, just a girl. Imagining her face in ways no one normally gets to see only made me want to torment her even more. I smirked from a distance, watching her squirm pathetically with the vibrator jammed between her legs. Let her fully taste the humiliation of screaming out on her own, convulsing uncontrollably.
