Shirouless Sakura
Sakura continued her desperate, clumsy ministrations, the agony worsening with each cycle of shocks as the intensity of the current gradually increased. Tears now filled her eyes as she screamed her throat hoarse from the torment being inflicted upon her most sensitive region.
In between the bouts of agony, Sakura noticed that he was clearly aroused, and that her suffering was arousing him further. However, despite that, it seemed like she was taking forever to bring him to orgasm, her ability to pleasure him hampered by the uncontrollable shaking brought on by the repeated and worsening shocks. She considered trying to use her mouth to speed up the process, but she was uncertain if she could keep control of herself and avoid biting down.
Finally, after several rounds of steadily-worsening shock torture, her tormentor, clearly frustrated with her progress, grabbed hold of her hair.
"How about you try using your mouth too?" he said, mockingly. "Maybe I'll actually feel it then."
Sakura could barely process what he was saying due to the agony she was in, until the current stopped once more and left her a brief respite. Panting loudly, she decided she had no choice but to obey him, despite the danger. If she did bite him out of reflex, then that was entirely his fault. Bending down, she took the head of his throbbing member into her mouth and began to lick and suck it as she continued to move up and down as before.
Then, suddenly, the torture device attached to her clit activated again, sending another jolt of agony through her. Sakura let out a loud scream before pulling back and gritting her teeth as the agony continued. She continued to move up and down shakily, as before and, once the pain stopped, she moved in once more, licking and sucking on the tip of his length before once again screaming and, then, pulling back when the pain came, this time managing to continue the licking for a little longer despite the increased current.
As the cycle continued, Sakura gradually became better at holding her mouth open during the torture, allowing her to continue clumsily licking for longer and longer.
