Sakura and Shirou
Heeding the girl's words, Shirou stopped caning the beautiful captive and stepped backwards, drinking in the sight of his seed on her back and the welts from the harsh caning she had received on her ass. Instead, he simply watched on with interest and arousal as the woman began to rub his seed all over Sakura's body.
Sakura, meanwhile, felt throughly humiliated as her released his seed onto her back, leaving her covered in his stickiness. Then, Emily began to rub the sticky liquid all over her back and ass before, finally, rubbing some into her folds, leaving her feeling sticky, soiled and degraded. She remained bound and helpless in the stocks as she awaited the next move, whilst Shirou continued to admire her, his arousal beginning to grow once more.
After a few moments, she heard Emily speak.
"Well, as far as first steps go, this isn't all that bad", she said, beginning to grope the captive girl's ass as she spoke. "But we've got more planned, don't worry."
Sakura began to moan as the girl groped her, feeling humiliated and degraded. Shirou, meanwhile, was aroused by the sight, but not quite yet able to harden due to his previous exertion.
