Yuri's tasks ranged from a wide variety of things. Her first one that she got during their dinner was to masturbate and send him pictures while doing so. But they weren't all like this. Sometimes he asked to forward him photos of how she was dressed that day. Other times, it was of her wearing something revealing or low cut, or just Yuri in her lingerie.
The more perverted requests were similar to her first. They involved showing her body during her private sessions, or to pose erotically for the camera. The tasks given to her occurred rather frequently and she got a few per day, depending on what they were. They were sent so often, that it seemed to be beyond the realm of blackmail at this point.
In the beginning, she thought he was using her to get to the other girls. The man did inform her that he was a fan of the group as well, and that he might feel the same way about the rest of the girls. She never let it get to that point, however, and in a way, doing this was protecting her closest friends.
But with how long they spent with one another, that quickly changed. Yuri thought he had a genuine affection to her, and that these pictures were for his own personal enjoyment. Knowing that, however, didn't make these tasks any easier. She was now in the middle of fulfilling her current mission, and she was panting and sweating in her room.
Yuri was sitting on her bed with her back against the wall for support, body completely naked with her legs spread apart. It was another case of masturbation pictures, but he wanted a photo of her pussy completely drenched in her cum after having a few orgasms. She was currently working on her third, and could hardly keep her eyes open.
With her hectic schedule, she already lacked sleep, and this much euphoria in a short time frame only made it more difficult to stay awake. But she had to carry them out as he regularly checked in on her during these lewd activities. She heard her phone buzz next to her on the bed and picked it up with her free hand.
"Have you cum yet?" The text from the man said, still labeled as "My Oppa." Using only one set of fingers, she quickly typed a response as he didn't like to be kept waiting.
"Not yet master." Yuri replied, turning her phone screen off afterwards.
Two of her fingers were still resting inside of her mushy pussy, wet from her juices and orgasms. The bed sheets were also wet as she's been sitting here for a while, plunging her fingers into her core the entire time. Yuri got in only a few thrusts before her phone vibrated again, and she promptly picked it back up.
"Don't call me that over the phone. Remember to call me your Oppa." It said. She typed back the same response as last time, but fixed the way she addressed him. After texting the message, she threw her phone onto the bed yet again to continue her mission.
Her two fingers were pruned down to the base of her hands and during the last hour, they spent more time inside of her pussy than out of it. She gripped her walls tightly around her digits as she thrust them inside furiously, wanting to end this. The first orgasm came quickly, the second took a while, and this third wasn't happening. Yuri's forehead dripping with sweat was an indicator of how long this has gone on.
Had she been doing this alone and uninterrupted, she might have already been finished. His incessant texting ruined her tempo and consequently pushed back her climax with each message sent. Whenever she tried to make herself cum by going quicker, it only delayed it further. Yuri was angered and she didn't realize she could just fake it. He would never know, but at the time of her arousal, she couldn't think clearly.
"Did you cum yet?" The next text message said, to which Yuri begrudgingly read and responded.
"No Oppa." Yuri typed back, now adding a third finger inside. Her index, middle and ring fingers were constantly prying into her core in attempts to reach her crescendo.
